Hy JimGnitecki, I'll probably get shot over this, but knowing what it costs to overhaul one of those engines, and what options it has, I would say a fair price for the engine would be between $2500.00 - $3000.00. For a perfectly functioning four speed hydramatic which requires no work, I would think $800.00 - $1000.00 would be fair, hope that helps. I'll start ducking now!
