With a 400 cubic inch (6.6L) engine, the Pontiac Firebird Trans Am kicked ass and lived up to the expectations set by the massive artwork on the hood.

There were two Ram Air 400 cu in (6.6 L) engines for 1970: the 335 hp (250 kW) Ram Air III (366 hp (273 kW) in GTO) and the 345 hp (257 kW) Ram Air IV (370 hp (280 kW) in GTO) that were carried over from 1969. The difference between the GTO and Firebird engines was the secondary carburetor linkage which prevented the rear barrels from opening. Bending the linkage to allow full carburator operation resulted in identical engines.
