Title: HEI MODULE
Post by: el mojado on August 05, 2014, 09:17:59 AM

I plan to use a stock Autozone HEI module with my MSD blasterII coil. Will that be ok? Which module will work? I already have the coil. I need suggestions on modules. Thanks.

I would rather see you use a USED G.M. module than any checkerzone/napaquest module. The ones that have failed on me weren't from G.M.

They might be cheap, but do you really want cheap?

Will it work fine with a Blaster II coil?

There are HEI module part numbers on the wiring diagram that I posted in your other thread

What HEI are you using?  If it's the old style it has a coil in the cap.  Not sure if maybe you're using a new small cap style.

Thanks Flusher. I just noticed the part numbers. I'm definitely gonna run my MSD dizzy with an HEI module wired in. Great idea!

Try them both and see which one runs better.  It is easy enough to swap them.

Don't forget to build the heat sink for the HEI module.

Good luck,

Joe

Sorry, but this begs the question  why?  Your original question as I remember was HEI or MSD.  So why build a morfidite?   Why not run either one system or the other?  What are the gains in re-inventing the wheel.   
Or am I miss reading this and the HEI module will be a back up to the MSD system?

I already have a billet MSD and box but they're used. I was considering a whole new HEI distributor. The reason I decided HEI is because If a part fails it would be easy to find replacement parts. Having an MSD box fail on me at the river would cost me a pretty penny. Its not expensive to carry a spare HEI module. So by just buying the module for about $25 I could have a reliable ignition and still be able to afford to buy a spare one. I had an HEI in my previous boat and ean with no issues and I had peace of mind that it was an easy fix if something went wrong. Previous to the HEI I had a full MSD (dizzy and box) and failure was always on my mind.

Both will be dependable if they are in good working order.  I have had both without problems.  At this time I have a MSD with no issues.
