Compression help ratio needed Just doing a little checking. I have a buddy with an LS2 and I have a set of ported 5.3 heads. I was wondering what the compression ratio would be on it if they have a 62cc combustion chamber on the stock bottom end.
Trying to make sure it still runs on 93 pump without an issue (tuned by a really good tuner of course). The one site I was looking at, it said 11.5, but I cannot remember how far out of the hole these pistons come out, or how thick the MLS gaskets are.
I'm also trying to get him into an ASA cam for the mere fact he isn't very knowledgable about the mechanics of cars, and the ASA cam is a put it in and be done cam. It can actually use his stock LS2 springs if I remember correctly (he's looking for more bark and a bit more bite) so that will give an idea of the dynamic CR.
Input?

stock MLS gaskets are .053 i beleive, and the piston sticks .005 out of the hole. let me run out to the truck and get the formula's and ill figure em out for you mike.
