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?
