would anyone know what the cr is?


I think with that dome it was marketed as a 12.5:1. Not sure if anyone ever really measured it to see.

2valve, I'll check an Action Fours piston as soon as I can manage to clear my garage enough to reach the kit, hopefully tonight.  I'll see if your piston crown looks like mine; it's a 12:1.  RR
