I have used their entire drop in HEI which include something similar to and am happy with the unit. I doubt any HEI is going to 9 grand but having a limiter is nice.

I use that module and matching coil in the HEI in my blown Malibu.

Couple things:

1. The module doesn't do much all by itself. The matching MSD coil doesn't do anything all by itself. TOGETHER, they are and AWESOME setup. This should not be surprising.
MSD designed them to work together to fix ALL of the usual HEI power drop-off problems at high RPMs. In other words, buy them BOTH together. If you can't afford both at the same time, buy the module first. The factory modules have multiple known limitations as RPMs increase. None of this changes the fact that even if you fix those module limitations the stock coil simply recharges too slowly to reach full saturation much above ~5000 RPMs. That's the final link in the chain that the matching MSD coil fixes.

2. 9000 RPMs? Probably not. Maybe. I've run them a little past 7000 RPMs ON NITROUS with no issues. Never imagined this simple combo could do that but it has for me in multiple distributors in multiple applications. It's the "Clark Kent" of ignition solutions. Not much to look at with the dorky glasses and bow tie, but under that facade is still Superman. I run this setup currently on my Malibu's mild supercharged 383 and its run for YEARS now without the slightest hiccup. Truth be told, I stumbled across this combo when my ignition box died and I had to get the car running again quickly on the cheap. Chucked in the MSD module and coil, ditched the ignition box and.... it ran BETTER than it ever did on the box! So I left it like that. Flash forward X years.... still running it. No issues.

3. If you are running boost/nitrous, you need smaller plug gaps than most factory HEI applications call for. I wouldn't run anything much larger than .035". And I wouldn't run "projected nose" plugs. This isn't really specific to the MSD setup but more general advice for anything boosted/nitroused.

So.... yeah, it works just fine in my experience.

This is going in a somewhat cruiser daily driver Olds 307 Cutlass.

More for reliability than high reving.

If that was the case i would just loose the module completely.


Thanks for the reply!
