One is between 51.8 to 52.7 CC on all four chambers and the other one is between 58.2 CC to 58.8 CC, how many thousands per CC do I need to tell the machine shop to cut the large one to match the smaller one Thanks in advance for the help Mr.Cab Racing and winning with Mopars since 1964.

Alcohol for fuel. The CR is 13.5. They are on my sons 451 now in a SC dragster and they just keep going....
