Np, could I get the centrifical advance cut back on the 383 one to 20 degrees. Would I save anything except on your parts and labor sending yo my distributor to redo. Reason for the confusion is I have 2/400’s and 2/440’s and not decided yet which one I’m putting in my 67 Cuda. I figured 20 degrees mechanical + 15-16 degrees initial + 10 degrees vacuum may be all mechanical in by 2500 rpm may be about right.
