The distributor is bad, i can't get any service out of Holley, MSD, nor Mallory, and it seems that the model needed is no longer available. The old (2005) programmer is difficult, and old tech; so it was going to cost me $750 for a Dyno guy to tune it, and I'd have to wait until mid September.

On a positive note: Edelbrock has been great to deal with and I ordered a Pro Flo 4 last Friday. Since this is a self leaening system I am saving on both a new distributor (since it comes in the kit) and the tuning. I think i am only getting like 3 mpg currently so if I can double those numbers it should all pay off.

I can't wait for it to get here since this rig can't leave town the way its running now (low speed cruising has been fine, but higher 2600 rpm cruising has pinging). I'm not a programmer and don't want to mess up anything.

The old rotor was spining/shaking 15⁰ on the PLASTIC Mallory distributor shaft, so i glued it to get by. (I haven't found a new shaft or rotor yet, and doesn't look like they make a replacement)

Price difference is not that big given that you get new intake manifold and distributor with pro flo kit, but I can't find any serious comparison online. MPI should be better than TBI, just wondering how much better?

I have a 401 in my CJ7 and wanted MPI-EFI as opposed to TBI and was one of the earliest customers of the new system (bought from Bulltear). I ended up moving out of the country for my job and it sat for over 10 years before I finished the engine rebuild and by that time, Edelbrock no longer provided support for the Gen 1 system.
Frustrated and not wanting to spend more money than necessary to get it running (and wanting a more simplified wiring system), I decided to go with FiTech’s multi-port EFI and adapt it to the Edelbrock MPI intake manifold. Edelbrock’s intake has a unique base for the throttle body, so I had a machinist buddy make me an aluminum adapter using Edelbrock’s gasket as a template for the outside configuration and FiTech’s gasket for their mounting configuration. I also used the Edelbrock injectors. I did have to get a new distributor also-like others have said, the one Edelbrock used was crap (Mallory if I recall).
I’m so happy with it and it saved me a couple thousand $ over buying a complete kit again. I love how simple the wiring is and was happy to get back space under my dash by losing Edelbrock’s computer and wiring.
I recommend those of you that bought the Gen 1 Edelbrock system to hang on to the manifold and consider using it for the FiTech system. Or selling it to someone that wants to do the same.
