HEI conversion Dodge ram truck coil

Hello Everyone,

I saw this post by TrailBeast: Installing a GM HEI Module

This intrigued me as to how I can get a really hot spark; I drive my car on propane, so strong ignition is very important.

I was wondering if this setup with the 94-97 Dodge Ram truck coil proved to be reliable. (I read that some coils are not suited for use because they make the GM module really hot)

Because I am debating the coil he suggested or the FD478 coil mentioned in this post on a different forum: HEI Electronic Ignition Retrofit How-To - Slant Six Forum.

I am already on the GM ignition module with a round 12v-rated coil.

Warm regards from the Netherlands,

Zip

I tried this ignition "upgrade" for my Slant 6 years ago. I used one of those brick-looking coils, but can't recall which one.(it was an Accel coil)

Another thing I did that paid off once was to mount a second HEI module right next to it. I could easily swap modules by swapping the plug. Use the gel and mount the modules on a small aluminum plate to act as a heat sink.
