  • .040 DOHC piston compression calculated

    Ok, well I did that all wrong. I used the calculator with the stock bore and got 11.7:1. Using the actual .040 over bore and having it calculate with the cc measurement, its actually 12.4:1. 12.2:1 with stock 3500 heads and 13.15:1 with stock 3400 heads.
