Old hat...
As noted originally, the distributor has 20º in it now. No argument about a too-fast curve, but it is set to 20º. I'll check that curve again, too. I questioned the tach I used at the time, will use another.
I'm running a 17" Flex-a-lite aluminum with a 2" deep blade. An 18" would fit better. They do make a 7-blade that is 2-1/2" deep. It is stainless though, NOT aluminum...it's going to be heavy.
My fan has no t-stat. I manually switch it...don't use it often enough to worry about it.
I have a backwards mounted 5" Mopar Bracket style scoop on the car with a hole in the hood even. The pressure well at the cowl puts air INTO the engine up to around 100mph.
Having referred to syncing the transfer port, I assume you are of the ported vacuum group and not the manifold vacuum group? For the former, by 'sync' you are referring to the amount of slot exposed, correct? I would appreciate some expansion on where you want that to be.

....and I'm targeting 14*.
You are
NOT of the belief that 12º+ will build heat that leads to detonation? At
some point 'more' initial advance is going to heat the engine. OR, you are saying you want 14º and if that builds heat...just get rid of it!
Thanks for your help.
