Welcome back!! Thank you for your service!!!!
A pulled motor no matter how complete and good running you say it is, is only a core (maybe $200) to the buyer unless you have first documented it running. The most used and biggest cliche' in the world is "It ran great before it was pulled. . ."
Before pulling it, take digital video of it running in the car and be sure to pan down to the engine number as it's running so that you can prove it's the motor you have out. Also, if possible, advertise it for sale BEFORE you pull it and allow the perspective buyer to see it run and if possible, drive the car with the motor before it's pulled. A god running and properly documented motor could be worth up to maybe $1000 for a guy who wants his car on the road while he builds his big motor.
Good Luck!!
