Re: piston everbore question.

this is one of those questions that you should probably figure out for yourself... otherwise your missing out on some key concepts. do some piston to wall clearance research.

LMAO this is the question of the year lol

self explanatory!

but why are your going overbore and not just a hone?? are the walls scored? if not just clean them up with a hone job and reuse the pistons if there still good with new rings installed.
