360 Truck Motor

Guy I know has an 87 360 4 barrel rebuilder truck motor he's thinking of selling and he'd throw in a 360 car oil pan as well. Since it's a rebuilder, any guesses as to what it's worth? Any issues with those late 80s motors? It's already been pulled so easy to load up. I need another motor like a hole in the head as I've got 3 slants, 1 273, 1 318, 2 340s, and a 392 Hemi. I keep telling myself one can not have too many motors but am sure my wife sees it differently.
