DUI install

Put in the DUI distributor yesterday in my '79 CJ7 with 304 v8. First time for me installing a distributor but everything went smoothly and it re-fired on the first crank. Noticeable increase in acceleration and power. Don't know if gas mileage will improve.
Only snag was having to grind on the hold down clamp to get it to fit the base of the distributor.
A bit expensive but worth it in my opinion. Went with Live Wires as well.
Set the plug gap at .50.

First off, nice work

I think you'll find that you blow through the rotor fairly quickly at that plug gap. You really don't need more than .040, IMHO. Got that bad boy on manifold vacuum?

Wanted to do this same upgrade. Glad it went well. Let me know if you have any pos/neg effects.
