I have been loseing power over the years on the truck. The cat has never been replaced and the moter never rebuilt. Could the cat be backed up?

Is the check engine light on? With that amount of mileage I would do a compression test to make sure the engine still has good compression. 120 to 140 psi.

The engine light is not on, and a compression test sound like a good test
