what will my new compression ratio be?
I had a 330 now .30 over keith black pistons kb203 with a .104 dome and i thin it was ground down.
I am just about to purchace a new set of heads edelbrock oval port marine. 110 cc
mercruse marine o.e. head gasket
new cam I .544 Ex .547 dur I 226 ex 236 lobe 112
intake performer 2.0 oval.
carb 800 holly.
hunting for exhaust.! trs

I will check the cc volume of that piston at shop tomorow, will also need to know how much deck clearance you have and what head gskt or the cc volume of the gskt you are using, to get exact

I mic'd it with a digital @ .104 and kieth black does not offer one like that.??
I am not sure how to check the deck clearance.
stock head gasket seams like it is pretty close to the fel pro marine that was on there before.
I did not measure can do that tomorrow if it helps.

formula 31 i was unable to get that to work.
i talked to edelbrock about the compression and they said it would be aprox 9.5 : 1 ?
i don't wont to over do the cast crank.
The rods do have new arp bolts.
