if you are not looking for more performance I would just clean and regasket the motor or maybe just new timing chain, valve cover and oil pan gaskets. if it runs well, there is no need to rebuild. I would never spend that much money on a motor I was going to rebuild, I would get a $100 junkyard mystery motor for that. put a new timing chain/gears on no matter what you do. I reringed a 93k mile junkyard motorhome 360 2 years ago for a friend, it runs great in he 72 fury wagon. put a new filter in the trans and shorten the drive shaft to fit your truck.
