360 Tune Up

I'm running electric fan and that is all I can use.
Thanks for the link. I will read it later and experiment with the curves.This is what I needed as all my previous experience was with SBC's. The vacuum can on the unit I installed today is adjustable. The previous one was not.

I usually use manifold vacuum on SBC's. Why would ported be recommended on SB Mopars? My engine is idling fine.
