I grew up around old school guys and no one says it better, "you can have 2k horsepower, but if you cant hook up why bother?"

How much compression would a 10cc dome with .040 head gasket and 62cc chambers give me?

Depends on CI and how far the piston is out the hole but I can tell you that is over 12 to 1 already

408CI with 14:1-14:5 compression with a 400 hit on ALKYHAUL

I wouldn't go 383. Check out coachs high compression 347CI, now that thing LEAVES. The 383 will limit you on heads IMO.
