Took a break from this and am now back at it. Trying to find out when the distributor bushing comes in to change the mechanical advance. One tuner swears by setting the mechanical advance as low as possible like 14 Degrees, others say Pontiacs like 20 or 24 degrees at the distributor. Total 34-36 Degrees, but that would to make initial at the crank 22 Degrees to end up with 36 total? I know they say don't pay attention to the initial, but what do you think? Have a new set of springs and will go at again this WE. That just is new territory to me.
