There were two Ram Air 400 cu in (6.6 L) engines for 1970: the 335 hp (250 kW) L74 Ram Air III (366 hp (273 kW) in GTO) and the 345 hp (257 kW) LS1 Ram Air IV (370 hp (280 kW) in GTO) that were carried over from 1969. The difference between the GTO and Firebird engines was that the secondary carburetor’s throttle linkage had a restrictor which prevented the rear barrels from opening completely, adjusting the linkage could allow full carburetor operation resulting in identical engine performance.
