I think there's a dynamic compression calculator floating around the internet somewhere... it depends greatly on the valve timing, cam duration, etc, unlike static compression which doesn't take that into effect. The only info that I can give is that I had a 396 LT1 with 11.8:1 static, but less than 9:1 dynamic.... I think that too much more than 9:1 dynamic would lead you into the world of race fuel
