1972 Dodge 318 new rebuild. The original HB is 7.25" OD and the new one is 7.1" OD. Would this not affect the relationship to the timing marks on the timing cover? I know the groove on the HB is correct TDC at the -0- mark. I timed it by ear at first and seems to run well. It felt/sounded/performed the best to me when the mark went above the 10 degree BTDC mark at idle. I couldn't really see, but think its probably set around 15, 16 degrees initial.
How could I set the timing more accurately given the odd size of the new HB?
