Qwk, are you talking about the KB167? I did the calculation with that piston, puts me at .012 under stock deck height w/ CR of 9.45 to 1. I think that is what I am going to do, change out the pistons. That should be cheaper than milling the block or heads. That should put me right where I want to be.
If I were to either mill the block or head, does the intake need to be milled some? Also, what about pushrod length?
I would take .040 and that would take 8 cc out of the equation put you at .055 quench. Intake Should be mocked up before milling either the head or intake. Same with the pushrods. Mock it up for the correct geometry. I assume that you haven't checked the deck, so even with new pistons it could require decking.
Or
Run it. However low compression 318's don't like very much cam if you require driveability. Stock cams were what I recall some thing like 250* so your cam your looking at is maybe 4 steps bigger than stock.
