6 cyl trans on v8?

Now this is just a hypothetical guess, but maybe the kid is identifying it by the pan shape and not by what it actually is. If it came off a V6 and has the same pan shape as a 727 then maybe it's actually an A518 overdrive trans and not a 727. I would get as much info as you can and pictures before making any sort of decision. I would personally consider it a good core until opened up and verified as rebuilt.
