When I installed a ProJection system on a '78 Regal with a Chevy 350 many moons ago, the biggest problem was the return line to the gas tank. I had to drop the tank and enlarge a vapor fitting on top to ensure proper flow back to the tank; I assume the return line is still required so you need to plan for it.

Very easy, and it was a cinch to tune with the adjustments on the control box. Sure was nice to throw that 2bbl carb in the trash can!!! This was in SoCal at the time and is probably illegal as hell now.

Looks like a nice kit. Reasonable price and even has a fuel pump block off plate. I've been pondering the Powerjection 3 or the FAST EZ-EFI. I'll take a closer look at the Pro-jection as well.
