As modern OHV V-8s became available and affordable in salvage yards, the Ford flathead V-8 rapidly disappeared from the hot-rodding scene. Hot-rodding in general moved away from the salvage-yard car builds as parts and labor became more expensive and many hot-rod shops priced themselves out of business.
Allen Johnson's Mopar Dodge Avenger Pro Stock. Pro stock is a class of drag racing featuring "factory hot rods".The class is often described as "all motor", due to the cars not using any form of forced induction such as turbocharging or supercharging, or other enhancements, like nitrous oxide, along with regulations governing the modifications allowed to the engines and the types of bodies used.
Even with the benefit of today's technology (aftermarket rods and stroker cranks), the upper limit of a Y-block is about 348 cu in (5.7 L), while the Chevrolet could be modified well past the factory limit of 400 cu in (6.6 L). The result was the introduction in 1958 of the 332 CID "big block" Ford FE engine which ultimately grew to 428 cu in
The 303-cubic-inch (5.0 L) ... hot rodders discovered the 215 could be stretched to as much as 305 cu in ... A 1969 "Ram Rod 400" with the W-30 package. 4-4-2 Rocket
The 430 was replaced by the 462 cu in (7.6 L; 7,565 cc) engine in 1966. Bore and stroke were entirely different at 4.38 and 3.83 inches (111.3 and 97.3 mm) and the 462 MEL engine produced 340 hp (254 kW) and as much as 485 lb⋅ft (658 N⋅m) of torque. This engine was fitted with hydraulic lifters and a four-barrel Carter AFB carburetor.
The design was soon bored to 260 cu in (4.3 L) and again to 289 cu in (4.7 L), then stroked to 302 cu in (4.9 L), settling on the most common displacement offered until the engine's retirement in 2001, nearly 40 years after the basic block design debuted. Two additional displacements were produced during the engine's history.
A gasser is a type of hot rod originally used for drag racing. This type of car originated in United States in the late 1950s and continued until the early 1970s. [1] [2] In the days before Pro Stock, the A/Gas cars were the fastest stock-appearing racers around. [3]
A NASCAR Cup Series engine with the maximum bore of 4.185 inches (106 millimeters) and stroke of 3.25 inches (83 millimeters) at 9,000 rpm has a mean piston speed of 80.44 fps (24.75 m/s). Contemporary Cup engines run 9,800 rpm, 87.59 fps (26.95 m/s), at the road course events, on Pocono Raceway 's long front stretch, and at Martinsville ...
