greetings and help kind ladies and sirs...

the vacuum advance doesn't back off soon enough either.

Well thanks for the input fellas. Serious J. you have no idea how long I thought deep and hard about doing a TBI set up the second we bought the Jeep. But by the time we got out the door the cost of the TBI was just a hair or two more than we had at the time. So now that we went ahead this way that's not an option for now. As far as the rest of it the distributer was just set up during a dyno tuning. The EGR is new as well. Soo I guess unless somebody can think of something else, it's gotta be some kind of physical damage I guess. Man this truck is quite a nightmare so far!

I can almost guarantee that the engine shop did not do what is needed to the distributor. It is not just simple springs and weights like a GM. The advance limiter slots are way too big and must be swapped with a smaller Ford unit or welded up to make them narrower, thus limiting the amount of mechanical advance. Then changing springs to get it all in by 2800rpm or so.

Tuning the vacuum advance is as simple as sticking the proper size allen wrench in the vacuum nipple of the advance can and screwing it in a few turns, then testing with a hand vacuum pump. There was a thread on here within the last few years with all the steps and how to set it up right.

Thanks Chevelleguy. Maybe I'll look to set her up with a better ignition system then and try things from there. What a pain in the arse! I guess I have been a bit spoiled with the GM HEI's

Welcome to the madness!
I have a 88 GW w/401 and a 260H in it. It is running a stock dizzy set at 12* advanced. I am pretty happy with the way it runs. Some day I will get the rear axle put back together so I can enjoy it more.

Welcome from Chino Az

Welcome to the club. I'm up here just North of Prescott in Chino Valley. Sorry to hear your having so many problems with your rebuild. Just a suggestion. Have you thought of going to an HEI distributor and ditching the old unit?Don't know how much it would help.

Curious what gearing it has in it. Hate to state the obvious, but a tall gear will make any rig feel like a dog. 130 at the axles doesn't sound that far off from a stocker, but it should be higher with the upgrades.

Welcome! Now about those pics of the green '91 wag...

As for your issue with the 360- how many miles on it since the rebuild? Maybe it's still just tight? Lots of good advice here to help you sort it out, maybe time and a few miles will help some.

Are you running a catalytic converter? Could be plugged.
