Complete late 70's 360....worth?

Hey everyone. I picked up this 360 a few years back with the intent of building it for another car....my wife happened to get a 67' Mustang instead so I wont be needing this motor. Anyways is a late 70's (i think 1977) 360, 100% complete and ran great when it was pulled, and I wanted to know if its worth selling. If not i'll keep it. Let me know what you think.
