Used 360 Value?

I went and looked at a disassembled used 360 last night for my Duster, as an option to building the core I currently have. The motor was disassembled (had a video of running) and had the 2380P "down in the hole" forged pistons (stock bore), used purple cam (lifters supposedly in order of removal), 340 X-Heads (2.02/1.60) with stock type rockers, M/T valve covers, Uni-lite distributor, performer intake and used Eddy carb (I'll discard these) and the E-body oil pan. Motor sounded good in the video, but intake valves are slightly sunk into the seat and the cam has some wear, but appears serviceable. What's the board consensus on a fair price? After looking at everything, I'm thinking $800 max, he's asking $1800. I realize I couldn't build this engine for that price, but it can't just go back together without at least a valve job and gasket set. What's the more realistic price before I decline?
