Stop in for a cup of coffee

Neighbor called me today asking if I still want to buy his 1968 340 engine and 727 tranny. Was a few years ago that I checked out the engine that is in a shed all torn apart but with X heads that looked good. The guy is a basket case and not trying to take advantage of him but told him not knowing what it needs if I can check out all the parts again I might be able to go $500 because that's all I can afford.
Waiting for him to decide what next.
