Oh man I love this car. I agree I think the price is a bit high but I'd venture to say if it's only 60-70 hrs left as you estimate, you should finish it yourself and then put it up for sale. A car that close to finished is better off finished than trying to sell as a "project" car IMO.
377 dry sump is boss!
P.S. you think that radiator/fan setup is gonna cool that thing on the street? I'm not so sure...
