The choice between AS amd AM is kind of dictated by your choice of body style. In AS the min weight is 3350# with a 5% deduct for auto trans so min is 3180# need a bigger car engine size would be 394ci [3350@ 8.5# per ci ] single 4150 style 850 carb AM is 2650# min @ 7.5 # per ci so around 375 ci with any size dual carbs this works with the smaller cars ( Cobalt, Cavalier, Sunfire, or ??? dont be afraid to ask alot of questions first , It will be a challenge !!! good luck Bob
