this isnt about truck performance just a general question so i put it here hope its right sorry if its not

Q: why is it that the SS and TA can use such huge **** cams even with the same size motors like 408 and that kind of thing but ours have to be so small (the cams that is ) you would think since it was the same motor it would all be the same. does weight and all play a part or drivetrain or what

A: still to come.......
