We run .016" on a 4 inch bore and would guess you'll need .020" ??

I hate water if you have sleeves it leaks somehow.
Takes up valuable room under the hood.
You would never believe me if i told you what you need to do.

I ran my 525 ih dry almost all year made no difference to performance just takes longer to cool it off if your hooks are close together might not be a great idea for you

So the clearance would go on all the pistons side as well as up near the rings or is it just extra around the skirt?
