HEI Coil

Okay, when it comes to electronics I can be pretty ignorant, so bare with me. I am installing an HEI distributor on an engine that was previously points. I've already got it wired, the whole 12 volt continuous ignition power and a seperate ground, but what I'm wondering is this. I've got the MSD dust cap that allows you to run a remote canister type coil. Will the coil that I was using previously (a stock coil) work with the HEI, or do I need to get a different one, and if so, what do I need to be looking for? Thanks for the help guys.

Yes, the stock coil should get you up and running, but eventually you want to get a high voltage coil (40,000 to 45,000 volts output) You may need to close the spark gap on the plugs to around .035 with the stock coil.

I agree with Oddrodder. I would look at the MSD Blaster 2 coil ($30-$35) It has more voltage than stock coils, and is OIL filled rather than epoxy coated windings. There was quite a controversy on this subject a few years back oil vs epoxy.

Doesn't the HEI have a coil built in? Or can they be purchased seperately? I do a TON of business with these folks...they have a 50K volts coil built in..

- Complete distributor with cap, rotor, coil
- High performance module
- 50,000-volt coil
- Die-cast aluminum housing and brass terminals
- Hardened steel drive gear and polished shaft
- No rev limiter
- Performance curve
