help decoding trans and rebuild

he told me over ther phone it was a lock-up type and I need to find a 440-727 from 70 or 71 to use as a donor to make mine worth a crap, I was just trying to verify that it was indeed a lock-up. Do you guys think this trans I have now would work with a 3000 stall and a tci complete overhaul kit would hold up to the occasional burnout/holeshot but no drag racing?


thanks
