An overhead valve engine , abbreviated ( OHV ) and sometimes called a pushrod engine , is a piston engine whose valves are located in the cylinder head above the combustion chamber . This contrasts with flathead (or "sidevalve") engines , where the valves were located below the combustion chamber in the engine block .
77-580: Allard Motor Company Limited was a London-based low-volume car manufacturer founded in 1945 by Sydney Allard in small premises in Clapham, south-west London. Car manufacture almost ceased within a decade. It produced approximately 1900 cars before it became insolvent and ceased trading in 1958. Before the war, Allard supplied some replicas of a Bugatti-tailed special of his own design from Adlards Motors in Putney . Allards featured large American V8 engines in
154-430: A 112-inch wheelbase and was offered with 3.6-litre Ford Pilot V8 and 4.4-litre Mercury V8 engines. 11 were built. In an attempt to further extend its line, Allard adapted its P1 saloon to produce the 8-seater, wood-sided , V8-engined, P2 Safari Estate. It too found weak sales, with 13 examples being built in total. The M appeared in 1948, remaining in production until 1950. It was a drophead coupé. The 1953 Clipper
231-465: A camshaft, but were located in the engine block as with side-valve engines. The 1894 prototype Diesel engine used overhead poppet valves actuated by a camshaft , pushrods and rocker arms , therefore becoming the first OHV engines. In 1896, U.S. patent 563,140 was taken out by William F. Davis for an OHV engine with liquid coolant used to cool the cylinder head, but no working model was built. In 1898, bicycle manufacturer Walter Lorenzo Marr in

In 1961 Sydney Allard, considered by many to be the father of British drag racing, built the Allard dragster, a supercharged Chrysler-powered slingshot. Constructed in 23 weeks between January and June 1961 at Adlards Garage, Clapham, in London, the car featured a 354-cubic inch Chrysler motor with front-mounted 6-71 GMC blower. Some speed equipment for
385-507: A light British chassis and body, giving a high power-to-weight ratio and foreshadowing the Sunbeam Tiger and AC Cobra of the early 1960s. Cobra designer Carroll Shelby and Chevrolet Corvette chief engineer Zora Arkus-Duntov both drove Allards in the early 1950s. The first Allard cars were built to compete in "trials" events – timed rally-like events on terrain almost impassable by wheeled vehicles. Built in under three weeks,
462-537: A light chassis inspired the development of the Chevrolet Corvette and the A.C. Shelby Cobra. An article on page 140 of the book Eagle Special Investigator by Macdonald Hastings , features Sydney Allard in "Special Investigator Drives a Racing Car", published by Michael Joseph in 1953. In 1958 Allard built a Steyr-engined sports car for sprints and hillclimbs, the motor purchased from Dennis Poore : "This Allard Special can certainly step off. It covered
539-474: A line growing obsolete in the face of advances in sports car design, Allard introduced an 'improved' model in late 1951, the J2X (extended). The chassis remained unchanged from the previous J2, but in an attempt to improve handling, the front suspension's rear attaching radius rods were redesigned with forward ones, which required a forward cross member and extending the nose past the front wheels. This, in turn, allowed
616-503: A loophole in the rules, the pushrod engine was allowed to use a larger displacement and higher boost pressure, significantly increasing its power output compared to the OHC engines used by other teams. Team Penske qualified in pole position and won the race by a large margin. In the early 21st century, several pushrod V8 engines from General Motors and Chrysler used cylinder deactivation to reduce fuel consumption and exhaust emissions. In 2008,
693-443: A low-volume car, and demand was high for cars in general, which led to the introduction of several larger models, the drophead coupe M and P . Allard used "J" for the short-wheelbase two-seaters, "K" for two- or three-seat tourers or roadsters, "L" for four-seat tourers, "M" for drophead (convertible) coupes, and "P" for fixed-head cars. As models were replaced, subsequent models were numbered sequentially. Built from 1946 to 1947,
770-522: A new record at the Prescott hillclimb . In 1937, Allard began producing modified Fords (in much the same way as the Chevrolet brothers had in the U.S.), selling them for £ 450 each. By the outbreak of war in 1939, twelve Allard Specials had been built. Sydney Allard's planned volume production was pre-empted by work on Ford-based trucks during the conflict. By the war's end , Allard had built up

Today the exceptionally rare automobile can fetch the better part of US$ 250,000 at auction. 62 examples were built, of which 57 were delivered to the United States. The L is a 4-seat roadster, produced from 1946 to 1950. It was on a 112-inch (2.8 m) wheelbase and available with a choice of 3622 cc (221.0 cu in) Ford V8 or 4375 cc (267.0 cu in) Mercury engines.

In 1963 the Allard put two rods through the block on Madeira Drive in Brighton. The car turned out to be a fifties-style dragster at a time when dragster design was rapidly evolving. Tire technology, with wider purpose-built drag slicks,
1001-514: A substantial inventory of Ford parts. The Allard Motor Company was founded in 1945, setting up in Clapham High Street, London. Using its inventory of easy-to-service Ford mechanicals built up during World War II and bodywork of Allard's own design, three post-war models were introduced with a newly designed steel chassis and lightweight body shells: the J, a competition sports car; the K, a slightly larger car intended for road use, and
1078-554: A time when sports racing car design was developing rapidly, the J2X was not as successful in international racing as the J2, as it was not as competitive compared to more advanced C- and D-type Jaguars, alongside Mercedes, Ferrari, and Maserati works entries. Thus, it headlined less often in major international races and of 199 documented major race starts in the 9 years between 1952 and 1960, J2X's garnered 12 first-place finishes; 11 seconds; 17 thirds; 14 fourths; and 10 fifths.

Allard then turned his attention to a twin-engined Steyr four-wheel-drive prototype, of great complexity. "All this leads to 9 litres of motor car and a very brave Sydney Allard surrounded by chains, shafts and engines." The car featured a solidly-mounted rear axle to which he planned to mount American-type dragster slick tyres. This

The Allard Special was put into limited production with Ford V8 and Lincoln V12 motors. A Ford-based special was supplied to a Mr. Gilson in 1937, while a four-seater was offered the following year. In 1937 Allard attempted to climb Ben Nevis , a mountain in Scotland, in his Allard car. The car crashed and rolled but Allard emerged with only bruising. Sydney Allard set

Sydney Allard was awarded the SEMA trophy for his performances at the races. In January 1964 Sydney Allard launched the Dragstar Dragon, a low-cost dragster designed by John Hume, powered by a Shorrock-supercharged 1,500 c.c. Ford engine, costing under £500 in kit form. Several cars of this type were produced. Among

OHC engines slowly became more common from the 1950s to the 1990s, and by the start of the 21st century, the majority of automotive engines (except for some North American V8 engines) used an OHC design. At the 1994 Indianapolis 500 motor race, Team Penske entered a car powered by the custom-built Mercedes-Benz 500I pushrod engine. Due to

It utilised a wood frame with aluminium panels on
2541-543: The OHV engine has powered almost all Buick automobiles since then. Several other manufacturers began to produce OHV engines, such as the 1906–1912 Wright Brothers Vertical 4-Cylinder Engine . In 1911, Chevrolet joined Buick in almost exclusive use of OHV engines. However, flathead "side-valve" engines remained commonplace in the U.S. until the mid-to-late 1950s, when they began to be phased out for OHV engines. The first overhead camshaft (OHC) engine dates back to 1902, in
2618-549: The P4 did little to help the J2X-C program, which collapsed after the car failed to meet its performance targets and the company itself liquidating during development. Insufficient research and development meant that Allard failed to keep up with cheaper and more technically advanced cars. The Palm Beach was essentially a year behind its competitors, the K3 failed to live up to expectations, and

By the mid-1950s Allard was struggling to remain solvent, and with the market weak due to a late-1950s US recession, the company went into administration in 1957, when manufacture of cars came to an end. The company also offered disc brake conversions for the Ford Anglia . In 1961, the company offered a dragster , the Dragon, powered by a Shorrock - supercharged 1.5 liter Ford, and

In the austerity period after the Second World War Allard struggled to source the raw materials for car construction, where the emphasis was on 'export or die.' It made no sense to import American engines and gearboxes only to turn round and export them again to the United States. Allard preparations for Le Mans in 1951 were delayed as Cadillac engines were in short supply, due to GM concentrating on production for
2926-413: The United States built a motorised tricycle powered by a single-cylinder OHV engine. Marr was hired by Buick (then named Buick Auto-Vim and Power Company ) from 1899–1902, where the overhead valve engine design was further refined. This engine employed pushrod-actuated rocker arms, which in turn opened poppet valves parallel to the pistons. Marr returned to Buick in 1904 (having built a small quantity of

At the end of the war Allard soon returned to competition, taking part in the Filton Speed Trials on 28 October 1945. He restarted his car company, coping with petrol rationing , material shortages and export quotas. A 1947 Allard-dealer advertisement stated: "Vacancies still exist on

The first competitive appearance was at the Brighton Speed Trials on 2 September 1961. There was talk of a new track record over the kilometre from
3157-412: The common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. However, some designs have the camshaft in the cylinder head but still sit below or alongside

The exterior styling still retained a robust Lexus flavor. Still, Allard designers tried to make it somewhat different thanks to a revised front and rear fascia, basketweave wheels, and a red and black interior. Unfortunately,

Allard founded the British Drag Racing Association, launched in June 1964, and served as its President. He followed this with the International Drag Festivals held in England in 1964 and 1965, featuring US dragsters and drivers. In 1964 Don Garlits , Tommy Ivo , Tony Nancy and Dante Duce participated in

Available both in street trim and stripped down for racing, the J2 proved successful in competition on both sides of the Atlantic, including a third place overall at Le Mans in 1950 (co-driven by Tom Cole and Allard himself) at an average 87.74 mph (141.20 km/h), powered by a Cadillac V8. J2s returned to Le Mans in 1951, one co-driven again by Cole and Allard,
3619-556: The first Allard was powered by a Ford flathead V8 in a body mainly pirated from a Bugatti. The V8 was moved backward in the chassis to improve traction. The car used the American engine's high torque to great effect in slow-speed competition. It debuted at the Gloucester Cup Trials, and later won the 100 miles (160 km) event at Southport Sands. After a time the front beam axle was converted to independent front suspension . Leslie Ballamy 's rather crude method

All three were based on the Ford Pilot chassis and powered by a fairly stock 85 hp (63 kW; 86 PS) 3,622 cc (221.0 cu in) sidevalve V8 with a single carburettor and 6:1 compression, driving a three-speed transmission and low-geared rearend, for superior acceleration. Front suspension was Ballamy swing axle, rear Ford solid axle. They were bodied in aluminium by Allard's friend Godfrey Imhof . Sales were fairly brisk for

An advertisement from 1950 for the Allard J2 stated: "Some overseas purchasers have preferred to fit the more powerful engines suitable for this chassis such as American Ford, Mercury, Cadillac, Ardun , Grancor etc." Sydney Allard raced an Allard J2 Chrysler in the Tourist Trophy at Dundrod Circuit in 1951. Allards were exported to

By 1933 he was competing in trials, retiring from the London-Exeter Trial that year in his Allard special, the Morgan converted by Allard to four wheels. He also retired in the London to Land's End trial. In 1935 he won his class, for unlimited unsupercharged sports cars, at
4235-719: The option of an Ardun hemi conversion . The J2 had a disturbing tendency to catch fire when started. Importing American engines just to ship them back across the Atlantic proved problematic, so U.S.-bound Allards were soon shipped engineless and fitted out in the States variously with newer overhead valve engines by Cadillac, Chrysler, Buick, and Oldsmobile. In that form, the J2 proved a highly competitive international race car for 1950, most frequently powered by 331 cu in (5.4 L) Cadillac engines. Domestic versions for England came equipped with Ford or Mercury flatheads. Zora Duntov worked for Allard from 1950 to 1952 and raced for

Both Zora Duntov and Carroll Shelby raced J2s in the early 1950s. Ninety J2s were produced between 1950 and 1952. In an effort to extend

The new roadster, weighing just 2,072 pounds (940 kg), was a potent combination of a lightweight, hand-formed aluminium body fitted with new coil spring front suspension, fitted with inclined telescopic dampers , and de Dion -type rear axle, inboard rear brakes, and 110 hp (82 kW), 267 cu in (4,375 cc) Mercury flathead V8, with
4466-406: The race at the end of the first lap, but on lap four he was the first to retire with collapsed rear suspension and a severed brake pipe. In 1952 and 1953 a sister car was driven at Le Mans by Zora Arkus-Duntov , a one-time Allard employee. Carroll Shelby also raced an Allard-Cadillac J2 in the United States early in his driving career. Thus the successful Allard formula of an American V8 engine in
4543-670: The runway disappeared through the timing traps. Time : 10.841 sec., which made the motorcycle riders whistle a bit. There were no arguments about the dragster's performance this time and "sack-cloth and ashes" were handed out to all dis-believers and certain Editors! [Congratulations, Sydney Allard- but a kilometre is a long quarter-mile and I still maintain that the dragster didn't live up to Allard high pressure pre-Brighton publicity.- ED .]" Sadly few spectators witnessed this achievement. According to Jenkinson: "Allard's temperamental machine eventually did 10.48 sec on its best run," for
4620-493: The sports car record at the inaugural Prescott Hill Climb on 15 May 1938, driving Hutchison's V12 Lincoln-engined Allard Special in a time of 54.35 seconds. That year Allard, with Ken Hutchison and Guy Warburton in the "Tailwaggers" Allard-Special team, competed successfully in trials, sprints, rallies and races. On 15 July 1939, Allard took a class win at the Lewes Speed Trials in a time of 22.12 secs. Allard won
4697-496: The standing-start quarter mile, which took place at Debden, Essex on 14 April 1962. This was the fastest quarter-mile time ever recorded in the U.K. The car was demonstrated at the Festival of Motoring at Goodwood on 14 July 1962. At Brighton on 15 September 1962 the Allard dragster clocked two runs at 22.30 and 22.04 seconds. A respectable performance but no outright win or record. Motor Sport reported: "It appears that before
SECTION 60
#17327982308114774-704: The team prize in the Monte Carlo Rally (L. Potter 4th overall, A.A.C. Godsall 8th, A.G. Imhof 11th) with Sydney Allard finishing in 24th place. In 1950 Allard finished eighth in the Monte Carlo Rally, then raced in the Targa Florio in Sicily where his Allard car crashed and burned. He bounced back with a third place at the 24 Hours of Le Mans that year , partnered with Tom Cole Jr. A gearbox failure left Allard and Cole driving for hours with top gear only. "Allard's determination and fearless driving captured
4851-536: The top section of the Brighton kilometre at 125 m.p.h. and won its class at Shelsley Walsh and Prescott, and two classes at Stapleford." He finished third in the unlimited sports car class at the Brighton Speed Trials that year, covering the standing kilometre in 25.99 sec. "Allard's air-cooled Steyr-Allard with Lotus front wheels and very compact body was third - although a sports car, it was started by means of an external battery." The car appeared at
4928-460: The valves (the Ford CVH and Opel CIH are good examples), so they can essentially be considered overhead valve designs. Some early intake-over-exhaust engines used a hybrid design combining elements of both side-valves and overhead valves. The first internal combustion engines were based on steam engines and therefore used slide valves . This was the case for the first Otto engine , which
5005-462: Was an attempt to cash in on the era's burgeoning microcar market. A tiny glass-fibre-bodied car powered by a rear-mounted 346 cc Villiers twin-cylinder motorcycle engine, it claimed to seat three people abreast with room for two children in an optional Dicky seat . About 20 were made. Allard introduced the Palm Beach roadster in 1952. It had a 96 in (2,400 mm) wheelbase, it
5082-414: Was an early indication of the influence of American drag racing on his designs. The car was never successfully run and soon abandoned. In the sixties Sydney Allard continued to compete in rallies mostly accompanied by Australian navigator Tom Fisk. They won their class in the 1963 Monte Carlo Rally in a Ford Allardette. Starting from Glasgow they reached Monte Carlo unpenalised. In the 1964 Monte Allard hit
5159-493: Was appointed a director of Adlard's on leaving school. He married Eleanor May in 1936. Their son, Alan, drove Allard's first British-designed dragster with such success Sydney was made first president of the British Drag Racing Association . "Allard commenced racing in 1929 with a Morgan three-wheeler , later converted to four wheels," which he ran at Brooklands and elsewhere. On 31 August 1929
5236-613: Was beyond doubt as hundreds turned up at Blackbushe Airport on 25 September 1966, to see a non-existent race. In 1991 Sydney Allard was posthumously inducted into the International Drag Racing Hall of Fame. In 2007 Sydney Allard was posthumously inducted into the British Drag Racing Hall of Fame. There is a part of the course at Prescott Hill Climb known as Allard's Gap, sometimes shortened to Allard's. This resulted from an incident at
5313-548: Was distributor of the superchargers, later also taking over production of them. Allard's son, Alan, marketed the Allardette 105, 109, and 116, using the straight-four-cylinder engine from the Ford Anglia and other Ford models. In 1966 Sydney Allard died on the same night a fire destroyed the Clapham factory and some of the Allard Motor Company factory records. The factory site in Clapham, South West London,
5390-438: Was first successfully run in 1876. As internal combustion engines began to develop separately to steam engines, poppet valves became increasingly common. Beginning with the 1885 Daimler Reitwagen , several cars and motorcycles used inlet valve(s) located in the cylinder head, however these valves were vacuum-actuated ("atmospheric") rather than driven by a camshaft as with typical OHV engines. The exhaust valve(s) were driven by
5467-568: Was given custom magnesium-alloy bodywork by Essex Aero . This 1953 car was a lightweight specialist racer, powered by a Cadillac engine claimed to produce 300 hp (220 kW; 300 PS). Entered at Le Mans that year, the Allard/Fotheringham-Parker car suffered a broken rear suspension, while the Duntov/Merrick car also retired. This was the marque's last effort at Le Mans. Seven cars were built in total, with
5544-477: Was held at Blackbushe Airport, Sat/Sun 25/26 September 1965, and RAF Woodvale, Sun 3 October 1965. The Blackbushe event was affected by torrential rain: "Unfortunately, the Blackbushe weekend was a financial catastrophe, and though Woodvale reduced the losses considerably, it was not enough to save Drag Festivals Ltd., who were forced to go into liquidation." A second Allard-Chrysler dragster "was constructed for
5621-485: Was powered by either a 1,508 cc (92.0 cu in) Ford Consul inline four or 2,622 cc (160.0 cu in) Ford Zephyr inline six. Priced under £1200, the MkI was built until 1958. It sold poorly. A Mark II was introduced in 1956, with more modern bodywork. It could be had with 2,553 cc (155.8 cu in) Zephyr or 3,442 cc (210.0 cu in) Jaguar XK120 inline six. The split front axle
5698-551: Was pushing speeds ever higher in the U.S. By the time Mickey Thompson showed up at Brighton in 1963 with his Ford-powered Harvey Aluminum Special the Allard dragster was looking distinctly dated. But this charismatic car was the true pioneer of British drag racing and a game-changer as UK racers adopted American methods and style. Allard was instrumental in bringing Dante Duce and Mickey Thompson to England in 1963 to demonstrate their dragsters. Duce appeared at Silverstone on 10 September (press demonstration); with Thompson joining in at
5775-419: Was replaced by torsion bars and coil springs were fitted in the back. Car designer Chris Humberstone licensed the Allard name from Sydney's son Alan Allard in the 1990s. He developed the J2X-C prototype racer, powered by a 3.5 liter Cosworth V8 engine and a transmission also grafted from an F1 car. Short of money, Humberstone allegedly attempted to work a deal with Toyota, which would have seen examples of
5852-684: Was the founder of the Allard car company and a successful rally driver and hillclimb driver in cars of his own manufacture. Born in London, England, Sydney grew up a member of a family owning a substantial Ford dealership, Adlard Motor, in Acre Lane Clapham . Educated at Ardingly College in Sussex he became a staunch member of the Streatham & District Motor Cycle Club followed by his brothers Leslie and Dennis and their sister Mary. He
5929-453: Was to cut the beam in half and mount the halves as swing axles and these swing axles were used on nearly all later Allard specials. Further Allards were soon built to order. Allard's brother, Leslie, was a customer, while racer Ken Hutchinson purchased a 4.4-litre (270 cu in) Lincoln-Zephyr V12 -powered version. It led to the pair forming a team, dubbed Tail Waggers, to race the car, which proved quite successful, including setting
