Strange erratic problem with 350 TBI engine.

Never did get a cable. Still need one.

As for the distributor. I pulled the one I had in there, to remove my intake manifold. THe gear was chewed up again. Bad.

How come I ran a GMPP LT4 Hot Cam for several years with no problems, and this LT1 cam is eating distributor gears?

I replaced it with an MSD Billet distributor I got for free. See how long it lasts.

Seems to me I recall some aftermarket cams required a bronze distributor gear,but I dont remember which ones in particular..
 
I am using a GM camshaft. It's a hydraulic roller out of a mid 90's Z28, so the second LT1.

What do you mean by "chewed up"?
Not being cute here, a description or picture might help diagnose what is going on. Any time any gear gets damaged, there are several things that can cause it.

Often by seeing the damage you can narrow down the problem. If you changed just the gear the last time, its possible it is something in the distributor causing it. Bushing that is seizing under speed and putting too much load on the gear, or too much slop that only shows up when its hot.

If you changed the whole assembly before, then its more likely something with the cam.
Either some fore and aft float, or a damaged gear.
 
It is chewing up the teeth on the gear. I am sitting in a tractor going back and forth across a field chewing up 17' feet of ground at a time a 4 miles an hour, so I can't really take a picture.

The first time I put a roller cam in this engine, it was a General Motors Performance Parts LT4 Hot Cam, and I reused the stock 1988 V10 distributor that was mated to a flat tappet camshaft. It worked fine for several years and thousands of miles. Then I installed a used "LT1" camshaft that General Motors installed in a mid 90's Camaro. John Ebke took it out if said Camaro and have it to me. I used it with same distributor that I had used with the LT4 Hot Cam. It chewed that gear up on short order. I replaced that entire distributor with one from a 1990 Camaro that had an L05 305 that came from the factory with a roller cam. I have since chewed that distributor gear up, in only a few thousand miles.

Man, I am envious. I am writing up the hydraulic change I did today in my little Mahindra 36 horse tractor.
I will be out tomorrow plowing with a dual point 14 inch plow after using a 5 foot disc harrow.
Just once I would love to run one of the big boys.

Since you have changed the whole thing before, it sounds like its either going to have to have the brass gear, or the gears on the cam have a problem.
 
Yep, since its tracked, it has to use braking for steering, and that can be problematic when you are trying to do small adjustments.
One of the advantages of switching to the synthetic fluid I just did, is that it says its designed for smooth operation of wet brakes and clutches.

Mine only has a wet clutch to switch on the PTO, but I like the idea of chatter elimination.
Yours might benefit from some slight friction modifiers to let the brakes apply a little more gradually and smoothly.

But, being as I just saw one of your models for sale used for $306,600, I would be real hesitant about putting any additives or off brand oils in it.......

And I agree about the IVT. That was why I wound up going with the brand I did. Kubota, the only other company that offered a tractor in the size I wanted with a cab, only offered it with the hydrostatic transmission.

They are nice on lawn mowers, but I don't like them for heavy duty farm equipment.
 
It's a rented tractor, I'm not doing anything to it besides fueling it up and driving it.

Not anymore. The last time I tried to buy it, you had to use paypal. I don't ever plan on using paypal.
