Why go all out for a daily driver with a stick shift? A stock engine will handle 500 Hp just fine. No need to spend the cash on P&P, Cam, HP Coatings, etc. Better off to spend the money on a sweet set of twin turbos. Fast spooling, better egt control, and better resell value when you decide to get into a different truck.
With only 88K, why mess with new bearings, rings, etc? An abused motor with 88K will last another 300K if you keep up on the oil changes.
Your money, your truck, but in my opinion, if not going for a full out purpose built truck, no need to go that deep. That's why you, me, and my neighbor bought a cummins, it's already built right from the factory!
