Motor that has been sitting 15 years

I found out last week that my 318 had a bad piston. Instead of rebuilding the motor, I took a chance and bought a used motor off of Craigslist. It’s a rebuilt 318 with about 5,000 miles on it. The problem is the motor has been sitting for about 15 years.
The motor came out of a truck so I have to change the motor mounts, water pump, timing cover, oil pan and oil pick up tube.
Any recommendations (besides a rebuild) on what I can do to get the best chance of success from this motor despite it sitting so long?

Thanks,
Kris
