Learned the weak point in any GM HEI is the module. Failures are so frequent with many that some carry spares!!! Choose wisely

Forget about RPM claims unless you're a racer. A bone stock HEI will work to at least 6,000 RPM.

And as others have said, don't cheap out on an HEI. I've had good service from stock GM, stock GM with MSD internals, and MSD Street Fire.

I did have a flaky ProForm HEI that had too much paint between coil and ground wire ring terminal. Drove me nuts for a while, but scraping off some paint fixed the problem. It worked great after that.

Just remembered I had an MSD E-curve distributor for several years, but being stupid, I left it in a car that I sold. It's set up with DIP switches, but tricky to do until you understand the concept. I watched a TV show where the guys were installing one and they were totally clueless! Made me feel really smart! Unfortunately those suckers cost >$600 now. :oops:

FWIW, I've had at least 5 different HEIs and installed another 3-4 in friend's vehicles over the last 30 years, and have NEVER had a module failure. Carrying a spare isn't a bad idea, but but why not go all the way and carry a spare coil? And then a fuel pump, alternator, headlight, flat fix...

Yep GM modules are good modules most of the after market ones are Luck of the draw. And I 100 percent agree well if we're going to carry a module m8ght as well Carry an alternator, harmonic balancer,flex plate,starter,carb kit. Etc. Etc.

Ditch the modules and by an MSD 6AL box. This gets rid of the coil under the cap the module, built in rev limiter, and built in anti-theft. You can even by the adjustable timing control and adjust your timing on the fly. I haven't bought one yet. I don't see a need for it on my truck at this time. I went with a FAST dizzy. I had an Accell one that failed. It ran one day and not the next. I trouble shot the MSD box and I think the pickup on the dizzy died. I have had several parts fail like this on this truck during this last round of upgrades. A Jeg's brand fuel pump left me stranded in the middle of the road heading to work. I bought an Edelbrock one. It was expensive. So far so good. Sometimes I think these old trucks are haunted. :rolleyes:

I took my failed pump apart and the diaphragm has a metal tab(button) that the arm pushes on. It had some how moved out of position, thus no pump action. The MSD comes with good directions. I ran a hot, and a ground from the battery to the box. I used an external coil so you need a wire and ground to it. It comes with a new plug in connecter to the dizzy for the pick up signal.

Since we are fuel issues be aware many clear plastic filters are coming apart inside allowing debris to either go right to pump or carb or the filter itself to block outlet. Even the ones that may still be supplied by edelbrock have failed.

FWIW, I purchased this distributor for $83 based on the good reviews but wouldn't recommend it. https://www.amazon.com/dp/B08TB5KGNX/ The wire connections are cheap and fit rather loosely. I wish I would have bought a better one but it works for now, especially after new springs.
