Factory ICM

Why not the Delphi, which I believe was the OE part?

Have you tried them?

While we're on the subject of ICM's and coils has anybody tried NGK coils? I'm thinking when I drop in the 355 to replace the 33 year old coil.

Other than the original I’m still using, no. But on my 96, I do believe the original is a Delphi. At least the new Delphi is made in USA. I have a NOS Delphi on deck if and when needed.

My truck was abandoned for 15 years and I've been wanting to change the ICM for piece of mind as I get it back on the road. I have a DUI distributor in my Trans Am that I am happy with so I will probably go with one of their ICMs. My experience with them has been good aside from their initial curve for my engine being way off which I understand is difficult to nail on built engines the first go around. Shipped it back to them for a recurve and waited a few weeks but all is well now.

I have a Delphi in my parts stash, as well. No idea when it was made, or where. It was a Rockauto closeout, I think, so it could be older stock. I had originally gotten a new ICM from Orielly's, but had to do a warranty exchange after about a year, TWICE.

Note, this is the later Vortec ICM, not the TBI ICM, if it makes a difference to anybody.

The new Delphi’s are still made in USA, whether or not they are as good as the original’s I can’t say.

Unfortunately the US has had to cut cost and quality to compete with the cheap imports but if you buy domestic you keep American workers in jobs.

…and why I buy NOS.

Check out this pricey piece! It's for a 1986 MB 560SEL.

It's why I buy Genuine GM original-equipment stuff from the Treasure Yard. Starters, alternators, coils, ignition modules, entire distributors or coil packs, various switches and control panels, etc. I get stuff for 1/10 the price of "new", and "good used" OEM parts when carefully selected tend to be better than "new, aftermarket" stuff at the parts stores. I save things from going into a landfill, I keep the Treasure Yard in business, my out-of-pocket costs are minimal, and with each part I recover from the Treasure Yard, I'm totally failing to provide the Communists with my dollars.

You're probably better-off with the original module than a brand-new one. Don't change it until it actually fails. But do test your ignition coil--primary resistance, secondary resistance, primary/secondary to ground, and verify output power with a spark-tester calibrated for HEI. Most ignition module failures are caused by faulty ignition coils.
