Well for now, I need to run the Stealths that I have. I spent my motor building budget on a 451 that blew up because of an incompetent machine shop.
"incompetent machine shop"? Lord forbid! we know they're all motor messiah's! on a non-sarcastic note, I did some math on compression ratio vs cc's some years back and basically one cc will change the compression ratio about a tenth of a point. having a compression ratio lower than 9:1 will need just a little more than one cc for a tenth of a point, and compression ratios at around 10:1 will need slightly less than one cc for a tenth of a point in change. you'll never know the "exact" change without measuring everything but you can get close using the one cc/ tenth of a point thing.
