What do I need to put an hei in my truck?

[DT1]

I put an Ac Delco HEI distributor in mine a few years back. Like WIDESIDE72 said, make sure you get a good module. I had a problem burning modules out for some time. It seemed like I was changing them out about every three months. The problem always occurred after I shut the truck down. The module soaks up latent heat from the distributor body and dies. I tried Mallory, Delco, Accel, Davis Unified and Pertronix modules with the same results. Also tried different heat sink compounds to remedy the problem. I finally tried a Pertronix racing module, part number D2070 that only draws 7.2 amps and it has been working fine for almost five years now.

When you have an HEI that eats modules, change the coil. A bad coil will kill them. Some shops won't install a new module without doing the coil also for this reason. A lesson I learned when I was younger from a much wiser old mechanic.

Yup, I tried that already. The only one that will work in my Delco unit is the Pertronix D2070.
