70 RR clone price expectancy

what kind of dollars would you guys think about paying for an original 225 slant six car that now only has a 440 block with heads and intake, (intake not bolted down with only like 3 ports covered) looks like springs are gone on front because it is practically dragging the ground. quarters appear bondo'd (didnt have a magnet to make sure) because the paint is all cracked looking. not priced or marketed for sale, but it's at the guy's sister-in-law's house i think. i've been passing by it nearly everyday for almost a year thinking about taking a minute to check it out, i was thinking about 1000-1500 since the block was essentially just a block lol. anyways, heres a pic i snapped of it
