1978 Motorhome 360 & Longshaft 727

I am considering purchasing a '78 360 out of a motorhome. It is located about 200 miles from me. The owner is willing to put it on a engine stand and fire it up when I get there. I am planning on rebuilding this motor. Also included is a longshaft 727. All this for $250.00. What do you think? Should I make the drive?
