Which EFI to use
I have the Fast EZ EFI system...I like it alot....I looked at the MSD system, nice system, but after doing a little research found out that most people still ended up having to run a return line for fuel....Also I looked at the fact that the Fast system uses GM style sensors so they're readily available at parts stores (very high priority to me cause I don't live in the U.S ) as oppose to MSD you would have to send the whole throttle body back to get any repairs if need be, but you can control timing if you're running a MSD ignition system...I didn't do much research into the Holley system.....Also if you run the FAST system make sure you hook up the switch +12v wire, pink I think, to a good source!!!! Found out the hard way when I didn't , so I hook mine to a toggle switch.....
