Value of 1969 340?

I wont give numbers but take into consideration if it is ready to go back together or if it needs machined etc. I have one now, but i need to send the crank out, and have the heads gone over, and I haven't even checked the bore yet to see if the block needs to go overbore. so in my case I will sink money in it, and who knows what it will be worth in the end I may just break even:) its the numbers matching block for my car though. so there's that. I do think though value varies and it depends on "whats in it" so to speak. is it forged crank, 2.02 valves etc. X heads etc.
