I am trying to build up my stock 74 Monte's engine. I want to get Performer Intake, 4 bbl. But my Question is this: I was told that due to my stock dished pistons, any cam swap would not be worth much. Is this true? I was told by "73Malibu" that a Comp Cams XE-268H would work well with my stock heads, but are the pistons that much of a hinderance? I really want a cam, but if the dished pistons really are so bad, I don't want to waste money on cam! Help me!
