Has anyone ever tried one of these brand new dui hei type distributors? I need a distributor for my ic-392 and although I have several cores lying around, all of them are pretty beat up and from 345s. I noted from michael's post that 392 distributors have different specs, so even if I used one of my 345 distributors, I should have it recurved for a 392.

If you have tried one of these duis, are you happy with it? Were there any clearance or other issues with it? If you had another Scout, would you buy another one for it? Thanks,
 
Jesse,

I probably sell one to two of these distributors a month. I have received good feedback on the performance results with the only negative feedback being that it's a tight fit to install.
 
When an order is placed for the dui distributor, it is custom curved for the application based upon the data provided at the time of the order.

And a data sheet accompanies the dui unit when it is shipped to the end user.

This is why I do not stock any. Each distributor is ordered according to the vehicle it is going in to.
 
I bought one for my Scout about four or five years ago. It came with a modified thermostat housing and only took about 45minutes to install, including the plug wires. It made a huge difference in hot and cold starts, and improved the mileage, and gave my 345 alot more seat of the pants torque. The only thing I would recomend is carry a spare module (stock Chevy type, about 15.00 at napa), I left the ignition switch on once over night and had to replace it. Other then that I am very happy with it.
 
My dui has been the most reliable part of my engine.... All three of them....:mad5:

seriously best thing I ever did. The modified water neck and tstat housing it came with didn't help me at all and I wound up making my own. That would be because the waterpump housing on my 1980 Scout is different than the 1979 and earlier models. At least as far as I can tell.
 
What information is needed when ordering one?

I have a 1976 loadstar 1700 with the 345 engine. I have no idea if the truck has a governor...
 
Look in post #3 of this thread (I see you May have already visited that thread) and determine which of those two distributors you have currently. One of 'em has a mechanical tachometer drive, the other one does not.

Both are Holley governor distributors, both of those have been converted to a pertronix trigger. The segment added below the main body contains the "spinner valve" portion of the governor mechanism.

If you currently have a governor distributor, then you must also have a governor-operated carburetor. If it's a 345, that should be a Holley 2300g carb. A 392 inna medium duty would be running a Holley 4v carb, a 4150g. Typical governor setpoint on these motors is 2800>3200rpm though it could have been bumped considerably.

It is possible to disable the governor setup by disconnecting the vacuum plumbing and making some changes in the throttle setup on the carb. The governor plumbing on the distributor is simply blocked off.

Look at post #3 in this thread and you will see a freshly reconditioned 2300g used onna bc170 backcountry fire fighting rig.
