Re: L78 Dyno
Thanks for the advice, yes the top ring is a 2 piece. The bores have been measured. they are 5 thou over from standard. The piston clearance is 11 thou and there is about 1 thou in taper. The bore is not out of round.
What pistons would you suggest running with in terms of brand and profile. Given the bore dimension and condition what oversize would you suggest.....there is the usual 30 thou over but I am lead to believe and as you say you can order just about anything. Interesting point about the honing proceedure, does this mean honing with the cylinder head on? what is the reason for this type of honing?
