BB Head Volume Unknown
I need help in defineing my head volume (cc) to select the correct pistons for a LATE 69 BB rebuild at +.030. I want to stay close to the
original compression ratio 10.25:1. New pistons with domes are rated with the head volume for compression. My heads are #3964290 which is a 1970 454 head but was used on late 427's (same bore). Is there a place to find this info?? Dbabich11
