Remember that you're setting timing by the crank and the cam runs at 1/2 crank speed.
The spark would have to jump half the timing lead. Your 20* at the crank becomes 10* in the distributor.
Good point, that is what I was overlooking!
Goody, join fitech owners group on facebook. Decent amount of mopar guys on there that can help. As these mopars are trickier when using original equipment.
I am on there actually, but just lurking. It seems like a lot of complaining or people that haven't got a clue how an engine runs.
