Well, my crate motor is in the sub, and the old block is out, and waiting to go back for the core charge. The only thing is, the engine I took out, is better than the one I put in. Cast # is 959(its a 4 bolt), and the heads are #781's. From what I've come to understand,(thanks to this site mostly!!), those are pretty desirable #'s for a BBC. I guess what I am asking is what do you think its worth? The core charge is just under 700 bucks. Do you think I could get more selling outright? I guess what I'm asking is whats it worth?
