I am assuming a typo on the number. I think you are talking about a 3126B? If so, I would replace oil @ 5000 miles and have the oil tested. Repeat another 10,000 miles later. This will ensure the rebuild and sleeves were done properly. You will give up alittle in displacement but that is about it.
The other major item is to have the valves adjusted. Probably done at rebuild but check to make sure. Have them checked again @ 100,000 miles.
The only other item I personally would do is, run Lucas oil treatment. This will eliminate dry starts ect. If possible, run a block heater in the winter.
Thats about it.
Since this is a common engine, what did you pay for your rebuild?
We had one done last year and it was $6500

Yes.
They can rebuilt them now. Cheaper than replacing.
However, if your turbo blows and the fins go into the engine, forget about it.
We had a Fl 70 rebuilt.
Engine must be pulled to get to the back cylinders. Cylinder walls can't be too damaged for this type of rebuild.
The original engine was just short of 1,000,000 miles. We have since sold it to a friend and he has 150,000 on the rebuild and it is still going.
Who would've quessed?
