Honda and Clone Engines / Re: stock Predator 420 Head cc

For all a stock hemi 420 is about 35cc. After I cut .045 in the head for .030 pop out of piston I smoothed and polished the chamber I got 40cc. Now with a .030 pop out piston, .020 head gasket and 40 cc head I have 13.56 to 1. Let tell you the engine runs strong.
