That's pretty awesome! I had seen this listed on some of the FB Mustang pages for a few weeks. Nice to have the pictures for us Boss 302 fans to reference. The same seller has/had an Acapulco Blue 1969 Boss 302 for sale, also. He's apparently a well-regarded engine builder in the NW.
Here's another Boss 302 engine he has for sale: https://www.facebook.com/marketplac...wse_serp:f58fa9c6-3a82-4ac7-8993-cdb98acb5a1e
The $50K is a pipe dream. $15K for the rebuilt one, if the parts are ALL correct, is within reason. Original parts for Boss 302 parts are eye watering. Prices are even higher for 1969 Boss 302 unique parts. Chuck
