valve relief help needed Uncharted water, help needed
I'm in the process of fly cutting my pistons and i was looking for some references to figure out how many cc i am cutting into my piston so i can calculate my compression ratio
if i'm cutting eyebrows for the lack of a better word, does any one know how many thousands equal 1cc in my stock ls1 pistion,
tried the search engine, no good references just vague and generalized, what i did find, i didn't know if it was a cubed measurment or measured by the depth of eyebrowed cut in the piston.

The issue is you go per se .015, the center of the "brow" is deeper than the outside, so you can't just say x = y... only true way is to cc it... otherwise your better off just calculating your CR w/o factoring in the cut's.. It'll get you a ball park..
