I've been trying to do my homework and educate myself on EFI for my ZZ4, but thought I'd also ask those who have installed these systems how they like them. I'm looking at the FAST EZ EFI and the Edelbrock Pro Flo 2 at this point. Any comments regarding your satisfaction with these or other systems appreciated.

I have the fast ez efi on one of my old machines, the 68 pick up has a 454 with the fast kit on it. it works as advertised, its a warmed over engine and it starts like a modern injected truck, no more carb cold start, no more feathering throttles when cold, no more typical carb rich/lean conditions. its a kit i should have done years ago. The master kit comes with everything, not one extra item is needed, lots of fuel line, nice hardware kit as well. I have found that most times a "master" kit means your gonna buy something, not so here.
I followed the directions step by step with the exception of running the power wire right to the battery, that caused issues. As soon as i corrected that all was perfect. I have recommended this kit for my buddies as well, 3 other have bought it and love it too.

As KT said good system, easy to install and so far mine has performed as they advertise.

Thanks for the comments. Anyone have experience with the Edelbrock Pro Flo 2 that they'd like to share?

I went with the Holley Avenger EFI setup for my new 496. So far so good.
