    What's the % of loss between crank hp and wheel hp? Around 15%??

    Actually, no! I cracked 850° on the dyno, but usually stay around 750° on my daily use. I haven't had the pleasure of driving it since the new cam was installed.

    It was 686/7874 to the ground...so roughly 15-16% drivetrain loss.

    You don't think the OEM pistons will hold up?

    Honestly, I don't know. It was suggested to me to use PAI's high performance kits because it has coated monotherm pistons. But I haven't had the chance to do the research on them. I haven't heard anything bad. But my engine went back together because all the internals were in great shape.
