I also had great results with the MSD Blaster II coil at 40,000 volts. Now I have a fresh engine I've gone back to the stock 20,000 volt coil.

Basicly a high output coil is pretty simple in design any should be sufficient thru most any manufacturer MSD and Accel are good products and coils alone are not overly pricey. May also want to look into there ignition sytems can double shoot a spark usualy up to 3000 rpm.

Just as a point of information, I just ripped off a Brand New Accel Super Coil from my '72 AMC 360 and put on a stock coil from NAPA, and it runs much better now. For some reason, the coil was causing 3 of my cylinders to misfire, as I found out with a timing light, and at many times any given cylinder of those particular three would not fire at all for several minutes.

I'm sure it was defective, and not all of them are like that, but it is yet another "non-success" story of my experience with Accel. I would personally stick with quality names like MSD or Jacobs, etc. if you want good quality and reliability.

Once I isolated the coil problem, I also went and changed the Brand New 8mm Accel wires the previous owner had installed and went back to plain old 7mm Beldens from NAPA. I have used Beldens for many years, and have never had to replace a set on any vehicle due to wear/tear or being defective.

Just a point of info.

I totally agree. Accel was once the superpower in performance ignition. Now they are less than desirable. I have an Accel coil on one of my rigs, but only because it came that way. Mallory, Belden, MSD... all good!

Hell, yeah, HEI is a great easy conversion. You can also go with Mallory DUI, designed for use with AMC motors. A bit pricey for the new distributor setup, but a simple one-wire hookup, and parts are interchangeable with GM HEI, as I understand. Check out

I know one or both of these guys carries the systems. <img border="0" title="" alt="[Wink]" src="wink.gif" />

I have the D.U.I. (Davis unified ignition)H.E.I, It Works great! and a snap to install!
My only Question, Is it compatible with those aftermarket fuel injection systems? does anyone run a howell or holley projection?

Best $130 I ever spent on my Jeep. high quality, easy installation. Gives as much zap as you'll ever need unless you're running a hi-po cam and/or some other goodies.

An MSD Blaster 2F is a good choice too since it uses the same horseshoe connecter as a stock coil.
