HEI in Mopar ECU casing

Coming in way late to the game. My orange box is bad. Going to replace it with a cheapy from O'Reilly just to drive and looking into this. @TrailBeast are you still running this? It looks like it's not that hard to do, just wire the 4 pins on the HEI unit to the corresponding 4 pins in the Mopar box, right? I replaced my coil with one from Rev N Nator (originally planned on going that route). If I do HEI, can their coil be used or do I have to do something else?

5 years with the same 8 pin module replacing the Mopar box and the matching E core coil with ZERO issues.
Some of the canister coils (Like the Pertronics Flamethrower) can come close, but the E and C core coils are usually a hotter spark.
I have also put the HEI module inside a Mopar box and it works fine, but using the Mopar case as a heatsink is mandatory if the module doesn't already have one.
Heatsink compound (like computers use for the processor) is a REALLY good idea also.

Here's the one I did using an 8 pin module, (which has advantages over the four pin) and you will notice the screws for the diode stick up more than a stock unit, as I didn't want the screws to look modified.
This was to keep the look but the insides had to be removed to make room for the HEI module so the screws come though farther.
The second pic is not the one I did.
I just used that pic for the wire connection points.
Whoever did that one sucks at soldering.:D
