what about this one tubed 69 cuda ?

Ok, with the information provided now, I would lean more towards the $3K-5k range, and could possibly go higher with answers to some of the other questions. I don't bother to take into consideration what it might sell for once you finish it; you are buying it as an unfinished project and the price should reflect that. It's probably just me, but I usually try to figure out what I believe I could part it out for and offer a little more than that.

One other question I forgot to ask; is it set up for small or big block?
