Trading for another 74 Duster

I drive an 01 volvo c70 as a daily driver, but I'm tired of the high cost of driving a newer foreign car with maintainance, repairs and whatnot. I found another 74 Duster on craiglist the other day and it looks like the guy is excited about my trade offer. All of the exterier body work is done on the car and it's in primer. The only thing that's kinda bothering me is that the slant is missing the carb and the transmission is out. I have a great running slant and tranny under my shed, but I don't want to get wrapped up in too big of a project because I'm in college 3 hours from home. The guy said all of the wiring and interior is there, so I'm thinking that it'll be a good winter project to get a decent slant 6 driver fairly cheaply. He's sending me more pictures Sunday. What do y'all think?
