I have time to decide, but it will be at least 12.5:1. Just got off the phone with Chuck, he suggested a Callie's crank as well. The compstar crank they like better than Molnar and the Compstar is less money than the Molnar as well. Sounds like a no brainer. Called Callies as well and they agree, the compstar rods and crank are good enough for what i'm doing. At this point it is also looking like i will need a CP custom piston as well. Adding up fast, but still will be way less money than Tim had me spending. Not a dig on him, just a fact.
