72 duster resto
Lol well Ill do my best to build two motors next time and try all the disparate advice. For now I’ll leave it be. I do understand the premise of the offset in theory.
Now hunting down a proper ring file and wishing id found a machinist to just build the full bottom end for me. Lol
So with a .020 overbore. Does that mean bore is 4.020
4.020 bore x .0065" gap factor = 0.026”
Brian at Imm engines suggested .028” for these KB107s
We will see how close I can get for the top ring. Currently gap is .017” and my largest feeler is .023
