New distributor

I've done the Weber conversion, haven't nuttered it. I'm thinking that my 22 year old distributor has spent it's life and wondering if I can change it out with a HEI and just eliminate the ECM completely. Anyone done this? It's time for new wires and cap anyway, and I'm thinking this couldn't hurt performance. Any and all suggestions and comments are greatly appreciated. The Weber swap out made a great difference in performance, making the 4.2 run smooth as ever.

Thanks to all responders...

The Nutter mod gets rid of the computer, just remove it from the Jeep.

Get a Cardone rebuilt distributor (about 50 bucks) from a 78 - 83 258 and your power and mileage increase will be very noticeable.

None of the HEIs have the correct advance curve built in for the 4.2. They can be made to work, but you will see little difference between the HEI dizzy and a new pre-smog Jeep dizzy.

You can make the Jeep pre-smog dizzy put out as good a spark or better by just wiring in the ICM from a GM HEI dizzy. Takes about 20 minutes once the Nutter is done. When I did mine, my idle improved and off idle power was noticeably better than with the Duraspark ICM (this is on the same ignition with a fresh Team Rush update).

I did the HEI years ago(and mc2100) and it made a huge improvement, I built my own from a GM 6cyl HEI and replaced the dist to cam gear with a gear from an AMC 304.
If you go HEI be carefull about the aftermarket distributers, some of them have hardened gears that will wear the gear on the cam.
I agree with old4x, the older dist is the way to go which I will be doing soon.
