Hypereutectic.
Stock 502 with forged pistons runs about .005 inch, if I recall, maybe up to .006 but not sure how that translates to using a Hypereutectic piston which is going to expand at a different rate than a forged piston.

I will ask, though, why you chose hypereutectic pistons for a forced induction application? Forged would be better.

The engine came with them...But i read that some guys have them on small boost engines and work fine.When i go to summit racing page where i found som spec for the pistons it does not say how much they expand...I read some threads where people say that forged pistons exspand the least and stock pistons expande the most so i guess my are somwere in the midle
