    pro x require a little more clearance, but work fine

    just get the biggest ones and hone the cylinders

    WFO,whats your thoughts on Pro-x with your cold fusion.For some reason I recall from the past Pro-x is a Hypertuectic style piston with higher silicone content.If this were the case would they tend to be a tad brittle and subject to pre ignition damage?Thanks for your input.

    I havent tried pro x in a nos application yet. I just completely tore down the motor a couple days ago, and the oems are holding up real good. Past experience with pro x was real good, but I had to go thru a few slugs to get the desired results
