Well, the R&R place 'should' have done the brake in procedure you're
speaking about. I gave them an outline from the machine shop and when I
questioned them about it they said they did it. However, one point I found
they did not do was to NOT put coolant into the radiator water for the first
50 miles. I asked the machine shop about this and he said (if I understand
correctly) that he wanted water to go to every nook and cranny in the engine
and that with coolant in the water it would be less likely for that to
happen. After the first 50 miles go ahead and put coolant. I'm going to
double check with him on the reasons when I see him again but that's how I
understand it.
Anyway, when I reviewed the R&R work before they were done I saw they put
coolant in. I again showed them the outline the machinist gave me which I
gave a copy from the git-go and they replied, strange, and took the coolant
out.
I think they had broken in many engines and just followed their method
without looking at the outline given to them.
The 'vibration' is felt only at idle. When I drive it I don't feel it.
Plus, I still have drive shaft vibration from the lift kit so at about 40
mph I get vibration from the drive shaft which is different from what I'm
talking about.
This engine was balanced with both the flywheel and clutch plate and
harmonic balancer as I understand it.

They sure aren't doing too bad. Like the others say check again and/or
it would still be a good time to make sure on those injectors.

Right, I'm definitely going to keep an eye on the plugs and I'm definitely
not going to forgo checking those injectors out for sure.
I'm going to take it to a local jeep shop for checkup ASAP.
Thanks for the input.

Re: Mike, here's the plugs after about a 10 to 15 mile run after new distributor and fresh rebuild
I always put water in first in case of leaks. After I run it for a very
short while & no leaks, I put in the antifreeze - friendlier to the earth &
(more important) friendlier to my wallet. don't know about the "nook &
cranny" thing.
