187,000 miles, just replace it, with that mileage rebuilding could get expensive if you need machine work.
The ready availability of remanned and crate engines has made rebuilding financially questionable after adding new parts, machining, and man hours.
The only real issue would be numbers matching.

Looks great, now your ready for another 200,000 plus miles of good memories.
I enjoy seeing older trucks go back on the road vs end up rusting away behind the barn or getting disassembled in a yard.

Yea it just gained about a 100 ponies over factory, besides better throttle response you might notice better fuel mileage.
The downside is all these extra ponies in front of an OEM trans can spell trouble.
I suspect you dont hotrod the truck, but just be ware the trans has some miles on it and may act out for attention in the future.
