The 1967 Firebird is a muscle car designed by Pontiac. The two-door car is available as a sport coupe and as a convertible. The car comes in five models: the base model Firebird, the Firebird Sprint, the Firebird 326, the Firebird H.O. and the Firebird 400.
1967 Firebird 400
The Firebird 400 is named after its 400 cubic inch displacement. The V-8 engine has a bore of 4.12 and the piston’s stroke is 3.75 inches. The compression ratio is 10.75:1. This engine can produce 325 horsepower at 4,800 rpm and 410 foot-pounds of torque at 3,400 rpm. To keep speeds down, Pontiac had installed a device that did not allow full throttle. Performance enthusiasts quickly learned that this could easily be removed, instantly adding 25 hp to their new Firebird, creating 350 horsepower.
