LOL - OH! I’d NOT bet against that one. I’ve done it and have come across 7.8-1.

IF - Key word there! IF the heads get killed and/or a thin head gasket is used/used over again… whatever… a small gain could be made. IF - There’s that word again - a rebuilding is in order, I gave my opinion on ratio as seen above and think it’ll be good for 87 and the small Hughes cam.
