Re: 85 GMC dirt cheap refresh

Not much progress on this one, as I have "Dads79gmc" in my shop getting some body work done on it right now. I have been driving it a bunch though getting the bugs worked out after the motor swap. The new parts store fuel pump was causing a bunch of problems, pressure was to high causing flooding, and about 8 mpg! After I figured out what the problem was, I installed a fuel pressure regulator, and have been fine tuning the quadrajet, and I'm getting a little over 16 mpg now. I can live with that till I can get a wide band o2 kit ordered up. This one has definitely grown on me though, I think I will do a nice build to keep on it.
