smokin_powerstroke

Right now I have a 11.1:1 forged 408 and decided nitrous is not the way I want to go. So if I were to swap out my 62cc dart heads to the AFR's with 72cc chambers; what would my compression drop to assuming I kept my gaskets the same? I really have an itch to throw on either a larger procharger or possibly wait until Magnuson comes out with their tvs 2300. I realize that if I could get e85 I probably could run some meth and not change the compression but I can only get 91.

nothing?

Here is a link to a compression ratio calculator, should give you the answer your after, just need to know , bore, stroke, deck height, piston valve releif cc, head gasket thickness, and chamber volumn.
