The Filthy Forty is a gasser from the early 1960s.[2]

Filthy Forty is a Chevrolet 283-powered 1940 Willys entered by the team of Hill & Zartman. It won the NHRA C/G national title at the 1963 Nationals, at Indianapolis Raceway Park, with a pass of 12.70 seconds at 110.42 mph (177.70 km/h),[3] and would win the 1964 Nationals with a pass at 11.95 seconds at 116.82 mph (188.00 km/h). The car would end up sold to a racing team in Wisconsin, where it would be destroyed in a crash in 1965.[1]

The Chevrolet 283 V8 used in the car would be modified with JE Pistons, Crane Engineering Headers and a Isky Racing Camshaft. The engine would run a Compression ratio of 14:1, and a maximum Horsepower and RPM up from 310 bhp (314.3 PS; 231.2 kW) @ 5,500 rpm to 435 bhp (441.0 PS; 324.4 kW) @ 9,500 rpm. The engine would be fit to a BorgWarner 4-speed, with a 6.58 Gear Ratio. The new Small-Block engine, significantly larger than the 2,199 cc (134.2 cu in; 2.2 L) Go-Devil I4, would mean that even with the significant weight reduction, it would only lose around 385 lb (174.6 kg) from the standard Willys.
