Well if my information is correct, Mopar Performance is discontinuing their ignition boxes. We are left with installation of a complete new ignition system or one of only a couple of aftermarket replacement plug in ICU boxes.
I have been testing every type of parts store replacement boxes I can get my hands on,and none of them are good for performance. I have tested a couple of boxes that are supposed to be performance replacement ICU's that I wouldn't run in a stock vehicle.
We are left with the Rev N Nator and the new FBO , or old stock.
Just letting you know while you can still get something

There are a few guys installing the 4 pin GM HEI ecu in a stock mopar ECU box, $20 bucks for a part store one and I think MSD and accel make some.

You have to remember the original HEI was designed back when Mopar ignition systems were designed. They weren't much better . An Accel module is an okay choice but current through it is still limited due to its size.
I have never been a fan of GM HEI because it dropped current at high rpm. Okay for a strock engine but thats about it.
I like and use the Rev N Nator the newest FBO box is a decent performance piece I just dont personally like the looks of it or how the Rev limiter his set.

What a surprise

Thanks for letting us know Keith

Kieth what would you suggest for my app: Circle track & heat races may be 15 minutes & feature races may be 30 minutes, mostly WOT reaching 6200 at the end of the straights. Some idling (5-10 minutes) in the pits & when setting up. Using a regular 70's electronic dist. Coil would need to be round stock appearing, any ECU & if it looks too outlandish I could hide it or camouflage it.

To bad the are dropping the ecu's. they had one hell of a long run! I am running a chrome box on the street right now it runs good I will pick up a spare chrome and try out either a rev or another fbo I have had the old style fbo before it was ok. don't know about the new stuff though.

The Revonator works great in my hemi car, that being said the MSD in my drag car also works excellent.
If you are doing a track car id go with the MSD.
Easy to install and you can hide it in the car or under the battery box.
Wiring it up is almost as simple as plugging in the stock ECU and you don't need the lousy ballast resister.

MSD for a performance build, pertronix to replace points .

And a suitable re-curve for all!

what are the EXACT coil requirements for a revanator?

There are no EXACT requirements for the coil on the Rev N Nator. But as a disclaimer I'm not the one of the people that designed it. The intent was to make a nice performance replacement that would work with all coils. To the best of my knowledge,the coil that FBO sold with his original system is the only one that doesn't work well with it.
I personally have tested many different coils and even a stock electronic ignition coil worked okay with it. Very high rpm is where coil selection gets a little pickier
I tested a different brand ICU recently that told you you had to use a certain resistance coil and a certain resistance ballast resistor. But you cant find that out until you order the ICU and read the enclosure
Keith

specifically what are the deficiencies your finding in the ICU's?

And which ones have you tested?

Have you tested it against a magneto?

Lets see,,,.....
Wells, Standard, no name parts store stamped " made in China", Old FBO,New FBO, Mopar Orange Chrome, and Gold, HiRev7500, 10 or 12 revisions of Rev N Nator, and a knockoff Orange Box from either ProForm or Jegs
Then test many of them with Accel Super Coil, Accel Super Stock coil, MSD Blaster 2 and 3, MSD HVC coils, Firecore coil,stock coil, generic replacement coil, Mallory Promaster coil, with and without .085 and 1.6 ohm ballast resistors.
Tested against an MSD6, Accel300 digital and Firecore ready to run distributor. Some on high compression and low compression engines.
I have several hundred dyno pulls on file. So its pretty hard to give a general answer on the downfalls
In most cases the ignition either pulled dwell or just did not perform well at peak torque where cylinder pressure is highest.

I bought a Rev-N-Nator box last year and ran it a short time. I've had detonation problems that prevented me from being able to take advantage of the dang thing. I'm working on lowering my compression ratio. I'm going to try the Rev box once my car is back together.

I'm curious if anyone has tried the Jeg's boxes. They have an "orange" one and a "chrome" one. The "chrome" one says Made in USA.
