Holley 750 backfire.

With that cam, I'd lower the total advance to all be in at 2200 & get as much initial as possible, That 3000 stall is abit tight too for the cam, at least a 9.5" 3800 would work much better. Good ignition is also key, I don't use Mopar ignitions or ECUs anymore, unless its on a mild engine, Get an MSD/Mallory 6 box & a MSD Distributor like this one, VERY simple to set the timing curve where you want it. Thats what i do anyways.
