I haven't tried a Quick Fuel, but I have 2 FastEFI's on my 72 4x4 pickup and 72 blazer. I haven't had any issues, but I can tell you that the grounds are the most important aspect of the aftermarket kits.

Second, is using a good distributer. You need a really clean signal from the distributor to the computer.

I used the MSD digital set up and have been really happy. I hope someone else with more knowledge will chime in. Good luck!
