formula is:
comb chamber cc's+gasket cc's+deck cl cc's+(displacement x 2.0483) divided by comb chamber cc's+gasket cc's+deck cl cc's= comp ratio


hope that helped BIOTCH!!

man you could have asked me that question. with a 347 depending on the thickness of head gaskets you use youre looking at somewhere around high 10s to11.1 give or take. in my 306 i had about 10.1 with those heads. man all this talk about building motors got me itching to get back to work asap and make money to build my 408 then get the car down here.

your looking at about a 11.1:1 with like a .030 head gasket thickness

well it all depends on his piston to deck clearance
