86-577: The first factory location was in Flint, Michigan at the corner of Wilcox (now Chevrolet Avenue) and Kearsley Street, now known as " Chevy Commons ", along the Flint River, across the street from Kettering University . It was commonly known as Chevy in the Hole. The current plant, at G 3100 Van Slyke Road, was built in 1947. In 1953 the first 300 Chevrolet Corvettes were hand built here before production

172-438: A Hewland 5-speed magnesium transaxle, and 10 in (254.0 mm) wide 13 in (330.2 mm) front/20 in (508.0 mm) wide 15 in (381.0 mm) rear magnesium wheels, it produced incredibly exciting racing. They ran 0–60 mph (0–97 km/h) in 2.8 seconds and over 180 mph (290 km/h). Reminiscing about the series, mid-70s Australian F5000 driver Bruce Allison said, "We never used first gear at

258-542: A brownfield . For numerous years before the idea of Chevy Commons took form in 2014, blight elimination at Chevy in the Hole was considered. In 2014, Mayor Dayne Walling announced two separate grants (of $ 1.6 million and $ 1.9 million, respectively) from the Environmental Protection Agency (EPA) to develop city-owned Chevy in the Hole into a park . Genesee County Historical Society president Dave White noted this represents

344-582: A crate engine for replacement and hot rodding purposes. In all, over 100,000,000 small-blocks had been built in carbureted and fuel injected forms since 1955 as of November 29, 2011. The small-block family line was honored as one of the 10 Best Engines of the 20th Century by automotive magazine Ward's AutoWorld . In February 2008, a Wisconsin businessman reported that his 1991 Chevrolet C1500 pickup had logged over one million miles without any major repairs to its small-block V8 engine. All first- and second-generation Chevrolet small-block V8 engines share

430-472: A $ 315,000 grant from the Michigan Department of Environmental Quality will be used to start work on the fifth and final phase. The fifth phase will feature additional walking trails, a parking lot, and possibly also a sledding hill. In 2021, the state announced plans to develop the site as the county's first state park. Chevy Commons is part of a broader, $ 36.8-million project to change

516-617: A $ 900 million new body shop at the Flint Truck Assembly complex. The project was first announced in 2015 and replaces the old body shop. The new body shop is a separate building that is connected to both the Flint Metal Center stamping plant to the south and the main assembly plant to the northeast. The new body shop was scheduled to open in 2018. GM has spent $ 2.8 billion on the complex since 2009. On October 12, 2017, GM announced it would invest $ 79 million to bring

602-464: A 2011 GMC Sierra Denali HD. The 13 million vehicles consist of 4 million cars and 9 million trucks. In January 2014, production began on the new K2XX generation of heavy-duty pickups for the 2015 model year. Some light-duty crew cab trucks were also built at the Flint plant. A new $ 600 million paint shop (Flint Assembly Paint Operations) was announced in December 2013 and opened in 2016, replacing

688-578: A SCCA Formula A open-wheel class designed for lower cost. The engine was also popular in Formula 5000 racing around the world, especially in Australia and New Zealand where it proved more powerful than the Repco -Holden V8. Weighing 1,350 lb (610 kg), with a 525–550 hp (391–410 kW) iron block and head engine positioned near the car's polar moment of inertia for responsive turn pivoting,

774-626: A bore of 4.00in and 3.25in stroke. The exact displacement is 326.7256 cu in (5,354 cc). Power ranged from 225 to 383 hp (168 to 286 kW) depending on the choice of carburetor or fuel injection, camshaft, cylinder heads , pistons and intake manifold. In 1962, the Duntov solid lifter cam versions produced 340 hp (254 kW), 344 lb⋅ft (466 N⋅m) with single Carter 4-barrel, and 360 hp (268 kW), 358 lb⋅ft (485 N⋅m) with Rochester fuel-injection. In 1964, horsepower increased to 366 hp (273 kW) for

860-531: A factory 'cross-ram' aluminum intake-manifold package using two Holley 600 cu ft/min (17 m /min) mechanical secondary carburetors for Trans-Am racing. It was available only as off-road service parts purchased over the Chevrolet dealership parts counter. With the Chevrolet `140 1st-design off-road cam, the package increased a stock 302's horsepower from 360 hp (268 kW) to approximately 400 hp (298 kW). Chevrolet went so far as to carry

946-583: A four-barrel Quadrajet carburetor and L46 hydraulic cam, dome piston (+0.16 cu in (2.6 cc)), 186 heads, and a four-bolt block. Years: 1967–1980 The L48 is the original 350 cu in (5.7 L) engine. It was introduced for 1967 in the Super Sport (SS) version of the Camaro (which used it until 1969) and for 1968 in the Chevy II/Nova (which used it until 1979). In 1969, it

1032-435: A high-lift camshaft. The 283 had a 3.875 in (98.43 mm) bore . The stroke of the 283 was 3 in (76.2 mm), like the 265. The 283, famous for being one of the first engines to make one hp per cubic inch, is also famous for being the evolutionary stepping stone that would later give rise to small-blocks and to the "W" blocks, ultimately culminating in the Chevrolet big-blocks. The last of this family

1118-711: A high-performance L-48 option for the 1967 Camaro . The exact displacement is 349.85 cu in (5,733 cc). One year later, it was made available in that form in the Chevrolet Nova , and in 1969 the lower-compression mainstream LM1 version became an option in the rest of the Chevrolet line. As had been the case with earlier versions of the small-block, the 350 was available in the Beaumont sold by Pontiac Canada, which unlike its U.S. counterparts, used Chevrolet chassis and drivelines. Many variants followed. Years: 1969–1970 The L46 became an optional engine for

1204-412: A lasting impact on the series' ability to conduct high car-count finishes and close competition events by the degree of mechanical success it provided to a series filled with star international Grand Prix drivers like Mario Andretti , Mark Donohue , David Hobbs , Graham McRae , Brian Redman , Jody Scheckter , and Al and Bobby Unser . The 327 cu in (5.4 L) V8, introduced in 1962, had

1290-618: A new product, the GMT480 , began at Flint the previous year. Additional versions of the GMT400 trucks were added to Flint from 1996-1998. The large commercial Chevrolet/GMC C3500HD chassis cab trucks began production in October 1997 for the 1998 model year. GM began production of GMT800 based Chevrolet Silverado and GMC Sierra HD pickup trucks and chassis cabs at the plant in August 2000 for

1376-622: A new trim shop to the complex. In June 2019, production began on the new T1XX generation of heavy-duty pickups for the 2020 model year. The refreshed 2024 model year T1XX heavy-duty pickups began production in March 2023. As of 2020, Flint Truck Assembly currently produces the Chevrolet Silverado HD and GMC Sierra HD Regular, Double, and Crew Cab models. The plant is the sole production facility for GMC Sierra HD and Chevrolet Silverado HD dual-rear-wheel (dually) models. It splits

1462-400: Is being redeveloped in phases, starting with the first phase: planting shrubs, building walking paths, and creating car parking on the southwestern end of the site. The second phase concentrated on connecting the site to county and regional trails, enhancing views of the Flint River, and improving access for fishing. By 2015, millions of dollars had been spent on cleaning up industrial waste on

1548-525: Is largely an improved version of the Generation I, having many interchangeable parts and dimensions. Later generation engines have only the rod bearings, transmission-to-block bolt pattern and bore spacing in common with the Generation I and II engines. Production of the original small-block began in late 1954 for the 1955 model year, with a displacement of 265 cu in (4.3 L), growing over time to 400 cu in (6.6 L) by 1970. Among

1634-574: Is part of a broader, $ 36.8-million project to change the landscape of the Flint River in Downtown Flint. The state of Michigan has committed to developing the site as a state park . Between downtown and Kettering University along the Flint River in Flint, Michigan , what is now Chevy Commons was the site of a sawmill and a paper mill before becoming the home of Flint Wagon Works in

1720-407: The 1969 Chevrolet Corvette . It was a higher-performance version of the base 350 cu in (5.7 L) V8 with casting number 186, 2.02 / 1.6 in (51.3 / 40.6 mm) valve heads and had an 11.0:1 compression ratio requiring high octane gas. This produced 350 hp (261 kW) (SAE gross power) and 380 lb⋅ft (515 N⋅m) torque. It was also available in 1970 with

1806-551: The trailhead for the Genesee Valley Trail that was constructed to connect it with Flint Township . Also that month, Chevy Commons entered phase two of its construction, as work on building the green cap continued. On September 24, 2016, Chevy Commons hosted its first event as a finished park: a children's biking event called Cycling Circles. In May 2017, a pedestrian bridge linking Chevy Commons with Carriage Town and connecting two already-existing segments of

In 1967, a new design high-rise cast-aluminum dual-plane intake manifold with larger smoother turn runners

2064-423: The 1880s. It is better known as the site of a former Chevrolet factory called Chevrolet Flint Manufacturing but widely known as "Chevy in the Hole". Automotive manufacturing at the factory began in 1904, and it employed 14,000 workers at its zenith. It was also the location of the Flint sit-down strike . The last buildings on the site were demolished in 2004 by automotive parts supplier Delphi , leaving it as

2150-462: The 1967 Z/28 before they used it on the L88 427 cu in (7.0 L) Corvette. It eliminated the production breaker-point ignition allowing greater spark energy and more stable ignition timing at all engine speeds including idle. This was one of the least talked about yet most transformative and comprehensive performance and durability upgrades of its time. Many of the 302s off-road service parts were

2236-710: The 2001 model year. The factory's next-generation product, the GMT900 -based trucks, began in February 2007. The factory also produced the GMT560 Chevrolet Kodiak/GMC TopKick medium-duty trucks, which were phased out in 2009 after GM discontinued that division. Starting in 2010, GM produced some light-duty crew cab pickups here, supplementing production in Silao, Mexico. On September 30, 2010, Flint Truck Assembly built its 13 millionth vehicle,

2322-420: The 265 / 283 cu in (4.3 / 4.6 L) small-block family. Of the three engines in this family, two of them, the 265 and the 283, made automotive history. The first of this family was the 265, introduced in 1954. The 265 had a 3.750 inches (95.25 mm) bore . The stroke of the 265 was 3 in (76.2 mm), like the 283. The 265 cu in (4.3 L) "Turbo-Fire" V8

2408-442: The 3.875 bore. Five different versions between 188 hp (140 kW) and 283 hp (211 kW) were available, depending on whether a single carb, twin carbs, or fuel injection was used. Horsepower was up a bit each year for 1958, 1959, 1960 (290hp), 1961 (315hp). The 1957 Rochester Ramjet mechanical fuel injection version produced an even one hp per one cu in (283 hp (211 kW), an impressive feat at

2494-700: The 327 and later versions of the small-block V8. The 327 was fitted in the English Gordon-Keeble . Ninety-nine cars were made between 1964 and 1967. It was also installed in many Isos , until 1972 when General Motors started demanding cash in advance and the Italian manufacturer switched to the Ford Cleveland V8 . In 1968, the 327 L73 developing 250 hp (186 kW) was part of the CKD packages exported to Australia from Canada for use in

2580-528: The 350 is the most widely-used small-block engine of all time. Though not offered in GM vehicles since 2003, the 350 series is still in production at a GM subsidiary in Springfield, Missouri, under the company's "GM Genuine Parts" brand, and is also manufactured as an industrial and marine engine by GM Powertrain under the " Vortec " name. All Chevrolet V8s, from the big-blocks to today's LS7 and LS9, evolved from

2666-670: The 4-bolt center-three main caps each fastened by two additional bolts which were supported by the addition of thicker crankcase main-web bulkheads. When the journal size increased to the standard large-journal size, the crankshaft for the 302 was specially built of tufftride -hardened forged 1053-steel and fitted with a high- rpm 8 in (203.2 mm) diameter harmonic balancer. It had a 3/4-length semi-circular windage tray, heat-treated, magnafluxed , shot-peened forged 1038-steel 'pink' connecting rods, floating-pin in 1969, forged- aluminum pistons with higher scuff-resistance and better sealing single-moly rings.

2752-488: The Bel Air sedan, the basic passenger car version produced 162 hp (121 kW) with a two-barrel carburetor. Upgraded to a four-barrel Rochester, dual exhaust "Power Pack" version, the engine was conservatively rated at 180 hp (134 kW), and with the "Super Power Pack," it was boosted up to the power level of the Corvette. A shortcoming of the 1955 265 was its lack of any provision for oil filtration built into

2838-470: The Pontiac division to share its valvetrain design in Chevrolet's new 265 V8 in 1955, so that both engines were introduced the same year with the same valve train design. A side note to Pontiac's V8 was that the engine was supposed to be introduced with 1953 cars, and all 1953 and 1954 Pontiac cars' chassis and suspensions were designed for the engine that did not make it into a Pontiac until late 1954. This

2924-522: The Q-jet carburetor returned in 1973. A 'divorced' exhaust crossover port heated well-choke thermostat coil was used to provide cleaner and faster engine warm-up. Its cast-aluminum distributor came in two styles, single-point had an ignition point cam designed to reduce point bounce at high rpm (Camaro) and transistorized (Corvette). Both distributors had a vacuum diaphragm to advance ignition timing at part- throttle for economy and emissions. Pulleys for

Another popular service-parts-only component used on the 302 was the magnetic-pulse Delco transistor - ignition ball bearing distributor. Introduced in 1963 on Pontiac's 389 and 421 cu in (6.4 and 6.9 L) drag racing engines, General Motors fitted it to

3096-473: The balancer, alternator , water- pump , as well as optional power steering , were deep- groove to retain the drive belt(s) at high rpm. In 1969, the 302 shared the finned cast aluminium valve covers with the LT1 350 Corvette engine. Conservatively rated at 290 hp (216 kW) ( SAE gross ) at 5800 rpm and 290 lb⋅ft (393 N⋅m) at 4800, actual output with its production 11.0:1 compression ratio

In spite of its novel green sand foundry construction, the lack of adequate oil filtration leaves it typically only desirable to period collectors. The 1956 Corvette introduced three versions of this engine—210 hp (157 kW) with a single 4-barrel carburetor, 225 hp (168 kW) with twin 4-barrels, and 240 hp (179 kW) with two four-barrel carburetors and

3268-416: The body was manufactured by Fisher and the chassis, suspension and engine assembly was performed by Chevrolet. The Fisher operations were halted on June 24, 1970, with the entire factory turned over to Chevrolet. Flint Assembly ended production of Chevrolet full-size cars in 1969. It last built passenger cars in 1970 with the mid-size Chevrolet Chevelle and Monte Carlo . The last car built at Flint Assembly

3354-401: The city officially celebrated the start of work on Chevy Commons with a groundbreaking ceremony. The former brownfield was redeveloped into restored grasslands , meadows , and woodlands while walking trails were created on the site. Its design features green spaces, low-maintenance native plants , and wetlands that are intended to control the cost of stormwater management . The site

From 1954 to 1974, the small-block engine was known as the "Turbo-Fire" or "High Torque" V8. However, it was the 350 cu in (5.7 L) series that became the best-known Chevrolet small-block. Installed in everything from station wagons and sports cars to commercial vehicles, boats, industrial equipment, and even (in highly modified form) in aircraft,

3698-467: The development work of racers like Roger Penske . Every part in a SCCA Trans-Am engine had to be available through local Chevrolet parts departments to encourage their use by anyone who wanted them. While the 302 became a strong Limited Sportsman oval track racing engine in the hands of racers like Bud Lunsford in his 1966 Chevy II, its bore/stroke and rod/stroke geometries made it a natural high-rpm road-racing engine and were responsible for its being among

3784-555: The end of the HQ series in 1973–74, due to US emissions regulations, the performance of these engines had dropped to the same or lower than Holden's locally manufactured 308 cu in (5.0 L) V8, which was not yet subject to similar regulations, so Holden discontinued using the engine. The L48 V8 was the standard engine in the 1975–1980 Chevrolet Corvette. The L48 V8 Corvette engine produced 165 hp (123 kW) in 1975. Power increased to 180 hp (134 kW) in 1976 and stayed

3956-509: The first time in almost 200 years that the site is not being used for manufacturing or commercial purposes. According to Walling, Chevy Commons was conceived to provide event space and recreational areas as well as recognize the site's automotive and Native American history . He conceived it as "an interesting, natural space right in the heart of the city". Christina Kelly, of the Genesee County Land Bank , noted that

4042-459: The intermediate displacements were the 283 cu in (4.6 L), 327 cu in (5.4 L), and numerous 350 cu in (5.7 L) versions. Introduced as a performance engine in 1967, the 350 went on to be employed in both high- and low-output variants across the entire Chevrolet product line. Although all of Chevrolet's siblings of the period ( Buick , Cadillac , Oldsmobile , Pontiac , and Holden ) designed their own V8s, it

The large-journal connecting rods were thicker (heavier) and used 3 ⁄ 8  in (9.5 mm) diameter cap-bolts to replace the small-journal's 11/32. 1968 blocks were made in 2-bolt and 4-bolt versions with

5246-629: The same basic engine block . Referred to as a "small-block" for its size relative to the physically much larger Chevrolet big-block engines , the small-block family spanned from 262 cu in (4.3 L) to 400 cu in (6.6 L) in displacement . Engineer Ed Cole is credited with leading the design for this engine. The engine block and cylinder heads were cast at Saginaw Metal Casting Operations in Saginaw, Michigan . The LT1 and LT2 engines are distinct from subsequent LS-based small-block engines. The Generation II small-block engine

5332-409: The same block dimensions and sometimes even the same casting number; the latter meaning engines were of the same block, but with different strokes (e.g., the casting number 3970010 was used by all three engines: 302, 327, and 350). This engine family was updated in 1968 for the use of 2.45 in (62.2 mm) medium-sized journals . The first engine in this family was the small journal 327 in 1962 and

5418-501: The same firing order of 1-8-4-3-6-5-7-2. The first generation of Chevrolet small-blocks began with the 1955 Chevrolet 265 cu in (4.3 L) V8 offered in the Corvette and Bel Air . The engine quickly gained popularity among stock car racers, and was nicknamed the " Mighty Mouse ," after the then-popular cartoon character, later abbreviated to "Mouse". By 1957 the engine had grown to 283 cu in (4.6 L). Fitted with

5504-530: The same in 1977. The 1978 saw 175 hp (130 kW) for California or high altitude areas and 185 hp (138 kW) everywhere else. Power increased to 195 hp (145 kW) in 1979 but decreased to 190 hp (142 kW) in 1980. The 1970 model year Camaro had a 250 hp (186 kW) high-performance two-barrel Rochester carburetor. In 1971, it dropped to 245 hp (183 kW), and net performance further dropped to 165 hp (123 kW) for 1972 and 145 hp (108 kW) for 1973–1976. It

5590-414: The site of a Chevrolet factory widely known as "Chevy in the Hole", it has been redeveloped and revitalized since 2015 as event space and recreational areas with restored grasslands , meadows , wetlands , and woodlands . It also features green spaces, low-maintenance native plants , and walking trails . In total, the creation of Chevy Commons is expected to cost approximately $ 17.3 million, and it

5676-402: The site, and the next phase of the project commenced: covering the concrete slabs of the site with 2 feet (0.61 m) to 10 feet (3.0 m) of topsoil , a total of 50,000 yards (46,000 m). Folliowing this, grass and trees were planted, and walking trails created. By June 2015, the first phase of construction of Chevy Commons was well underway. By "fortunate coincidence", it also became

5762-425: The start. We started in second, and even then there was so much torque , you'd get wheelspin through third and fourth gears." Prepared with a Lucas-McKay mechanically-timed individual-stack magnesium fuel-injection induction system that was paired with ported production car double-hump iron heads, a rev-kit fitted roller lifter camshaft, roller bearing rocker arms , and a virtually stock production crankshaft, it had

5848-472: The statewide Iron Belle Trail was planned. By that point, both the first and second phases of the project had been completed, with additional third and fourth phases planned as part of the broader Riverfront Restoration Project, which endeavors to naturalize the Flint River and make it more accessible, safer, and easier to use for recreation. The third phase concerns 9 acres (3.6 ha) of land along Kearsley Street (between Swartz Creek and Stevenson Street) and

5934-598: The time. This was the third U.S.-built production V8 to produce one horsepower per cubic inch, after the 1956 Chrysler 300B and Desoto adventure . Besides being available in the Chevrolet line, it was optional in Checker Taxis beginning in 1965. A version of it that was built by GM Canada was also available in Studebaker vehicles produced in Canada for 1965 and 1966. A 307 cu in (5.0 L) version

6020-471: The valve train design scheduled to be used at the time in the Pontiac V8 . Internal GM rules at the time stated that once an automotive division had introduced a technological innovation, no other GM division could use it for a period of two years. The stud-mounted independent ball rocker arm design patented by Pontiac engineer Clayton Leach, was scheduled for introduction in the Pontiac 1955 V8. GM forced

6106-656: Was a Monte Carlo on June 24, 1970. Since 1971, Flint Truck Assembly has only built full-size pickups, full-size SUVs, full-size vans, and medium-duty commercial trucks. During the 1970s, Flint was home to the full-size Chevrolet K5 Blazer and Chevrolet Suburban SUVs and the Chevrolet C/K pickup and their GMC counterparts with pickup truck production moved to Pontiac East Assembly in Pontiac, Michigan in May 1987 when Line #1, which made pickups, ceased production. However,

6192-412: Was around 376 hp (280 kW) with 1.625 in (41.3 mm) primary x 3 in (76.2 mm) collector Sanderson tubular headers that came in the trunk when ordered with a 1967 Z/28, and associated carburetor main jet and ignition timing tuning. In 1968, the last year for factory headers, they had 1.75 in (44.5 mm) primaries x 3 in (76.2 mm) collectors. A stock 1968 Z/28 with

6278-636: Was because the Buick division lobbied GM to postpone the release of Pontiac's engine, as it affected Buick's release of its new OHV V8 engine . A pushrod engine with hydraulic lifters , the small-block was available with an optional four-barrel Rochester carburetor , increasing engine output to 180 hp (134 kW), or 195 hp (145 kW) in the Corvette. The short-stroke 3.75 in × 3 in (95.25 mm × 76.20 mm) bore × stroke engine's 4.4 in (111.8 mm) bore spacing would continue in use for decades. Also available in

6364-572: Was built for GMH for the final run of the HK GTS327 by the Canadian McKinnon Industries. It was a lower compression version of the 1968 engine first used on the HK GTS327, and was dressed as a 1969 engine sporting all 1969 parts. The 327 was replaced in the mid-1969 HT Monaro by the 350 L48 developing 300 hp (224 kW). The 350 cu in (5.7 L), with a 3.48 in (88.39 mm) stroke, first appeared as

6450-456: Was expected to be completed by the end of 2017; the fourth phase deals with greening the area along the river on both sides of Stevenson Street in 2018. In total, the creation of Chevy Commons is expected to cost approximately $ 17.3 million. By July 2018, the third phase was complete, and the first three phases were open to the public. At that time, the fourth phase was expected to be complete by October 2018, at which point leftover funds and

6536-459: Was increased from 2.3 to 2.45 in (58.4 to 62.2 mm). In 1965, Chevrolet released the now-legendary L-79 , which was nothing more than an L-76 (11.0:1 forged pop-up pistons, forged steel rods and crank, 2.02 Corvette heads), but with the 30-30 Duntov cam replaced by the No. 151 hydraulic cam. In 1966, Checker began offering the 327 as an option. The Avanti II and its successors were powered by

6622-550: Was introduced for the Z/28 that the 350 cu in (5.7 L)/370 hp 1970 LT1 also used. Unlike the Corvette, the exhaust manifolds were the more restrictive rear outlet 'log' design to clear the Camaro chassis's front cross-member. It had a chrome oil filler tube in the front of the intake manifold next to the thermostat housing from 1967 to 1968. The first year had unique chrome valve covers with Chevrolet stamped into them without an engine displacement decal pad. In 1968,

6708-771: Was lowered to 8.5:1 in 1971. In 1972, the L48 (four-barrel V8) option for the Nova was part of the SS package. This is indicated by the fifth digit in the VIN being a K . 1972 was the only year the SS package could be verified by the VIN. The L48 engine was exported to Australia, where it appeared in the Holden Monaro from 1969 through 1974, and in the Statesman from 1971 through 1974. Towards

6794-483: Was moved to St. Louis in 1954. This factory also produced Chevrolet Bel Airs for the North American market. Encouraged to collaborate with the nearby Fake Pottery Company, GM shared some of the colors used for the car, such as sky blue, and as of 2020, the pottery manufacturer still makes ceramics using those colors, albeit in limited quantities. Production was split between Fisher Body and Chevrolet where

6880-436: Was previously part of Chevy in the Hole is being redeveloped into automotive proving grounds , including for autonomous vehicles , by Kettering University and General Motors . Chevrolet small-block engine (first- and second-generation) The Chevrolet small-block engine is a series of gasoline -powered V8 automobile engines , produced by the Chevrolet division of General Motors between 1954 and 2003, using

6966-567: Was produced from 1968 through 1973. Engine bore and stroke was 3.875 in × 3.25 in (98.4 mm × 82.6 mm). All 307s had large 2.45-inch (62.2 mm) journals to accept the 327's crankshaft . Pistons used with the 307 share the same pin height as the 327 but retaining the 283's bore size. Originally intended as the performance block, this engine family through the 350 cu in (5.7 L) became an all-purpose engine that saw use in many applications from Corvettes to commercial vehicles. All engines in this family share

7052-415: Was the 307 cu in (5.0 L), which was a stroked 283 with a medium journal. The 265 cu in (4.3 L) V8 engine was bored out to 3.875 in (98.43 mm) in 1957, giving it a 283 cu in (4.6 L) displacement . The first 283 motors used the stock 265 blocks. However, the overbore to these blocks resulted in thin cylinder walls. Future 283 blocks were cast to accept

7138-528: Was the Chevrolet 305 and 350 cu in (5.0 and 5.7 L) small-block that became the GM corporate standard. Over the years, every GM division in America, except Saturn and Geo , used it and its descendants in their vehicles. Finally superseded by the GM Generation III LS in 1997 and discontinued in 2003, the engine is still made by a General Motors subsidiary in Springfield, MO as

7224-431: Was the product of placing the 283 cu in (4.6 L) 3 in (76.2 mm) stroke crankshaft into a 4 in (101.6 mm) bore 327 cu in (5.4 L) cylinder-block. The 1967 302 used the same crankshaft stroke as the 283, but was forged steel for high-performance duty. This block is one of three displacements, 302/327/350, that underwent a crankshaft bearing diameter transformation for 1968 when

7310-463: Was the second Chevrolet small-block; the first Chevrolet V8 was produced in 1917. The 265 cu in Turbo Fire engine was designed by Ed Cole's group at Chevrolet to provide a more powerful engine for the 1955 Corvette than the model's original " Blue Flame" in-line six , the 162 hp (121 kW) 2-barrel debut version went from drawings to production in just 15 weeks. Cole's design borrowed

7396-402: Was used in almost all car lines—Camaros, Caprices, Impalas, El Caminos, Chevelles, and Novas. The 1969 L48s use a hydraulic cam, 4bbl Quadrajet carburetor, cast pistons, 4-bolt main casting number 010 blocks and casting number 041 or 186 heads. Power output was 300 hp (224 kW) SAE and 380 lb⋅ft (515 N⋅m) torque. Compression ratio was 10.25:1. The compression ratio of the L48
