Crisp, Clean, and no Caffiene. If you do not want to spend the money for the excellent FBO system, this is a strong second choice. The way to make a start stand ignition stsyem too. Works super. link page

How did you mount it? Are you using a heat sink?
Mount it on a piece of aluminum plate w some dielectric clear grease in between for the heat sink (required). Some one either on here or eGay sells a plate to mount it under the dist for twenty some dollars but just make your own & bolt it to the bottom of the dist & yes mounting it under the dist is the perfect place for it. The one I originally used was one from a '75 chebby 350 eng w the 4 identical 1/4" male terminals.
Mounting under the dizzy sounds perfect! Got any pics of yours?

Working on this, and have done a lot of research. Slantsix.org has a great page with lots of info. http://www.slantsix.org/forum/viewtopic.php?t=28732&highlight=heiUse the links in the first post for more info and parts list. I have about $80 invested and on my third design of a coil mounting bracket. I would like it to fit in the stock location. And might mount the HEI where the the ballast resistor was. I am tired of not being able to get parts at any parts store, (We have to order that). I want reliability so I can drive my cars any where. Adding relays for the head lights was the second best improvement To any old mopar in my opinion. First is having the steering box rebuilt by steer and gear.

Yea, slantsix.org has this fully covered. Here's the best page on that site. http://slantsix.org/forum/viewtopic.php?t=15779I made the unit below for my 73 Dart. It was wired like explained on slantsix including the relay. Notice the heatsink underneith and the electic grease under the module. Important stuff. Some guys just bolt the module to the inner fender to act as a heatsink, but I burned a few that way. This heatsink was adopted from a computer CPU heatsink. Worked great, if a little ugly (that can be fixed), and I've always copied it in every Mopar I've owned since.

Ok, now don't start hatin on me for thinkin it, but...I am fixing to install a GM HEI module on my truck *gasp* I was wondering if anybody else has done it, and do ya have pics? The wiring looks like it is very straightforward, and it will clear some clutter and simplify my wiring harness and hopefully ease the engines electrical needs.... don't be embarressed if you have GM parts on yer mopar! How did you mount it? Are you using a heat sink? Did you retain your original as a backup? Or did you remove your ECU system completely (which is what I'm thinking of doing)?
In 1984-85 when doing this mod,I simply mounted the HEI in a position to gain a little airflow,not a big deal really.

All the good information has been posted regarding the HEI swap. What I will post is that di-electric grease should not be used between the HEI module and the heatsink. Thermal paste should be.
I stand corrected as yes you are transfering heat not voltage (the 2 mounting screws ground it). Who/what/where can I get thermal paste for this one I'm doing and since I only need a wipe of it on this one module what kind of shop uses it so if need be I'll hit them up for a slight amt.
Here is a source for one of the "better" thermal pastes out there:
