Both cars are competing in the Pure Stock Drags, so modifications are limited to porting, blue printing and minor weight reduction without altering the stock appearance. That means stock intake manifold, stock exhaust manifolds and street tires (see below for more information about rules). The 1972 455 HO GTO is very rare as only 310 were built. The GTO is powered by Pontiac's 455 Cubic Inch (7.5 Liter) High Output V8 which was rated at 300 Net horsepower and 415 lb-ft of torque due to a drop in compression ration which occurred in 1971. The 1968 Firebird 400 racing the 455 HO GTO is also is very rare (only 110 built) since it's optioned with Pontiac's potent Ram Air II 400 cubic inch (6.6 L) which was rated at 340 horsepower and 430 lb-ft of torque. The Ram Air II 400 was the predecessor to the Ram Air IV and had round port heads. The Ram Air II 400 was no joke. This particular Ram Air Firebird is from high performance dealership, Royal Pontiac. The 455 HO GTO is a 4 Speed manual and the Firebird 400 is equipped with GM's Turbo 400 automatic transmission. So WHO WINs? Watch the video and see what happens.
