GM HEI conversion

I just put in a GM HEI into my I6 cj7 it works great but i have one question the hot wire i used to go to the distrubuter has a voltage reducer on it. it is a little white box on the firewall right above the valve cover. Ther are 14 something volts going into it and 12 something going out. Can i bypass the reducer? and if i do will it create a hotter spark for my ignition?

Any help would be appreciated

Yes.
It isn't needed on the HEI. [img]images/graemlins/40BEER.gif[/img]

I'll second that. You don't need it, and you're probably better off without it. [img]images/graemlins/grin.gif[/img]

Re: GM HEI conversion

In order for the HEI to be High Energy, it needs a full unrestricted 12 volts to it. Those readings were taken key on, engine off. Running the voltage is even less through the ignition resistor.
Toss the resistor.

Re: GM HEI conversion

1. The ballast resistor (that little sand colored boxy thingiee..) is there to limit the voltage to the OEM coil,
2. If it weren't there the coil would overheat and fail.
3. But since you've got the GM HEI installed,
4. It runs on full system voltage,
5. So hook 'er up direct to the full battery/alternator voltage,
6. And have fun....
7. You've gotten good advice in the previous post. [img]images/graemlins/40BEER.gif[/img] <--- Root-Beer
