'79 440 Motorhome short block - Should I buy it?

Thanks guys. I'm going to get the chassis like I want it and get it good and road worthy before I pull the 318. If funds are still tight when I'm ready (if I don't win the lotery - I guess I should play...) then I think I'll just get a valve job on those '67 heads and put my Edelbrock dual plane intake on it and hopefully have a solid tourque motor driver. I appreciate the help.
