DUI? It's junk.
Sometime's simplicity comes at a price. If you can't afford MSD, at least go with a Pertronix. It's not a glamourized chevy dizzy that has serious flaws directly from the manufacturer.

DUI is just a glorified version of GM's HEI, a very failure prone ignition. Having the module inside the distributor subjects it to excessive heat, which electronic devices absolutely hate, so they are prone to failure. Having the coil on top of the cap is a bad idea, too. Electricity actally will arc through the rotor, melting it until it grounds out and you have a no start condition. They are also prone to moisture damage, and in performance use prone to spark scatter above 4500 or so.When I was a GM tech in the '70s and '80, HEI repair was a daily task for me, at least it kept bread on my table.  ------------------

I have no experience with the DUI but I know people who like them. The GM type modules are prone to heat related failures.
I inagine if you have a hood scoop and a rigid fan, it won't get that hot under the hood..... [This message has been edited by Mpcoluv (edited 12-06-2003).]

Bottom line: the module belongs on the fender, not bolted to the engine, no matter how many scoops or fans you use.------------------

This is true. Chevy guys usually have more than one hei dist. If they can't figure out the problem with one they just try the others until they find one that works halfway decent. The advance mech. is a piece of crap too. They only work right for a few 1000 miles and have to be rebuilt. ------------------

If you cant afford the Msd then go to a junk yard and find a Ford Duraspark and box and coil. It is a very nice unit for about $25.00. Make sure the shaft only has a little play up and down and side to side. Bruce

Back when I drove a brand 'x', I carried a spare module, rotor, and cap-coil assembly as well  Sell the DUI to help fund the purchase of an MSD  BTW, the MSD distributor is only a two wire deal; plugs directly into the 6AL box that you've already got  ------------------

Just to add to what was already said:
Pertronix also make a Chevy style HEI distributor for fords. They have upgraded modules that are supposed to be better than the Stock GM parts. Im not keen on them based on the way things are so intergrated.However one more thing about chevy failures. Dont forget the small block chevy distributor is at the back, perhaps out of the cool air flow? Maybe that contributes to failures and certainly makes replacement hard in some applications because its so far back. If i had the money I would run a MSD probillet. For now I run a plain jane old distributor with crane XRi. I have a duraspark unit brand new on the shelf which I may put in come spring with an MSD module to drive it. I also use a "big cap" conversion and motorsport wires which together made a big difference to idle quality. The pertronix under the cap ignitor modules (both I and II) failed on my car so I steer clear of them now. http://www.geocities.com/ottouk_77/images/engine289.JPG ------------------
