piston wall clearance for 10-15 pounds of boost.
im dropping a couple 400s off next week for some machine work, 1 of them i plan to throw some slightly used parts in and slap a blower on. the pistons are ross .030 pistons that normally would need .004-.005 pwc. right now they measure 4.145 -4.146 on the skirts. if i were to have the cylinders honed to 4.151, or even 4.152 would that hurt? or would it even be neccessary to go after that extra .001-.002 clearance?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
