Quote: you could add some small domes to the pistons to push the CR up to 13 or 14:1. With that big stroke you only need a tiny dome to really crank up the compression.
On my 4.250" stroke, 4.375" bore engine, I calculated 13.2 CR just by milling the heads to 71cc. So, depending on your chamber cc, piston to deck, etc.; a small dome can get to 14 CR.
