Although the high-performance 429 Cobra Jets were still rated at the same power as the 1970 models, Super Stock and Drag Illustrated had disappointing results from its test of a 1971 Torino Cobra. They tested a Cobra equipped with the 370 hp (280 kW), 429 CJ, C-6 automatic, 3.50:1 gears, and were only able to turn a best quarter-mile time of ...
Later in the season, the Boss 429 engine was used by many of the teams, after it had finally been declared "officially homologated" by NASCAR president Bill France. The Boss 429 engine was homologated in the 1969 Ford Mustang Boss 429. In a very unusual move, Ford homologated the engine separately from the car in which it was to race.

This was the start of a trend of rules slowing down NASCAR, because the races were exceeding the technology of tires and safety over 200 mph (320 km/h). Ford, in response, also designed the 1970 Torino King Cobra with an aerodynamic, superbird-style nose, but it was abandoned. [14] [15]
The only fuel injected first-generation engine, its sole application was the 1970-1973 Ford Capri RS 2600. It was replaced with the RS 3100. Weslake developed a racing version of the engine, bored to 96 mm (3.78 in) to give 3.0 L; 182.8 cu in (2,995 cc) of displacement and producing in excess of 320 PS (235 kW; 316 hp).
