Ok , thanks Jerry.I have the 4.3 injectors so I should be good then running at 12 PSI.The only thing I didn't do is bump the timing.I think I am at the stock timing of 10 degrees, not the 13-14 like a lot of people are running.This engine with the way I have it setup is not the easiest to adjust the timing on with the electric fan and shroud in there.
