Atomic EFI vs. FAST EZ-EFI 2.0

Aloha Gang!

Now that the brakes on my car are thoroughly sorted (many mahalos to Scott Bell for saving my okole), I'm looking into Major Project #2: Converting to EFI.

Since most of the runs we do over here take us up Haleakala (at a touch over 10K feet), the car nearly refuses to run at the summit. I've been doing some research, and I've narrowed it down to two systems: MSD's Atomic EFI and Fuel Air Spark Technology's EZ-EFI 2.0.

I'm leaning towards the MDS system, as it interfaces with my 6AL control box and distributor, plus it's a returnless design (no need to plumb a return fuel line to the tank).

One thing I do like about the EZ-EFI system, is that it's E85 capable (not that I want to run it, but could in a pinch).

Has anyone had any experience with these two systems? Recommendations?

Mahalo,

Scott
