Replicaracer43 is correct , it was just thrown together with the parts I listed.
I obviously don't have much experience building engines like this. I was hoping to hear from somebody who has built something similar and hear about the results they have.
Just as a example, I had a customer with a steel crank 340, rebuilt back to stock specs, with the exception of a set of Keith black pistons, it had a vibration, and it had to have the assembly balanced to fix it.
