I'm confused. How many miles does this truck have on it, and how many TOTAL miles on the engine?
If the body and drivetrain really only have 50K miles on them, I'm impressed. OTOH, if it has more and you tore it down to do the headjob and didn't replace the camshaft, I think I hear a ticking time bomb.
Otherwise, sounds like a great truck and a great starting point for someone to get most of what you'd need to either wheel the piss out of it, or build it the rest of the way, the way you wanted it.
Good luck with the life changes.
