GM did not build a stage II
stage II was a bolt on that could be had form the dealer
mainly was the heads I never heard of a 72 stage II but I guess
that someone could have install a stageII package but no factory
stage IIs were ever built [img]/ubbthreads/images/graemlins/scholar.gif[/img] StageII was a over the counter package only No production cars built as a stageII The heart of the stage II was the cam 455 in 480 ex with 455 in and 480 ex duration An aluminum intake with a 850 cfm Holley on top The big thing was the heads
With redesigned ports good for an extra 50hp
