Life is soooo good again. Worked that Holley system every way imaginable and in the end happily tossed it. Talking to some guys that are big FI users on alcohol motors the cam we have has too much overlap which was blowing the fuel out as they put it. At idle it was rich and at high speed it was super lean and being a non programmable software system, it was never to be.
So I looked at some of the manufactures of carbs Barry Grant, Holley, Edelbrock, and Quardrajet and talking to the guys whom each collectively have 50 years a piece in racing, the conclusion was to go to Holley. Called Holley for their input and given this truck is 99% highway driven they where adamant against the Truck Avenger due to fuel mileage and vacuum issues. The suggested the Street Avenger version 570cfm and after discussing with the boys, we had reached a conclusion.
I installed a Jegs return pressure regulator, set the lbs at 7.5, made up all my new stainless lines, new filters and WHAM, fired off first click and is damn near tuned perfect out of the box. Very happy with its drive ability and the exhaust cleaned up and the the plugs are burning a nice medium brown...oh happy days!
All that is left is to rip all the FI wiring out, computer and modify the kickdown..
