HEI in Mopar

ken5124 said

I run both the mopar and the hei.. A flip of the switch and I can go back and forth between the 2... Found a wiring diagram on redneck fabrication website and then installed it on my 65 valiant..

I had previously run a straight hei system, but found it would not start consistently.. Now I start with the Mopar and flip in over to Hei for the hotter spark. Using an MSD BLaster 2 coil.

Works great so far..

And you point out the flaw in the system with HEI that sometimes gets overlooked: the module itself. As unreliable as some claim the ballast to be (I've never had a problem with one, guess I've been one of the few) the GM guys will cuss the module. If it's not treated correctly or installed properly it will give you fits.

Seriously, I'm not trying to bad mouth the swap. The HEI does have it's purpose. But since the hot ticket in Ford circles is to set the Duraspark up with the Chrysler ECU, and not the straight up HEI system, it should tell you something about the Chrysler set up.

Yeah, I guess you can make the claim that anything is better than the Duraspark system and we're talking a good ignition system for Chrysler, not Ford, but I say this makes a damned good claim on the Chrysler system itself.




Yes, this system has the HEI coil. But notice the resistor?
