Alright you gear heads, im looking or some opinions on something. looking at pistons for my car, I have a choice of getting cast pistons, and aluminum alloy pistons. both are hyperteutetic. the cast have that skirt coating and are made by sealed power, and the aluminum alloys are made by AE Clevite, and do not have the coating. The aluminum ones are chaper, and are the only ones that come in a set as to where the cast ones only come indivdual. also im looking to go .30. any opininos guys? would there be any gains and such?
