Lovely truck you got there. If you haven't considered parting with the power-pack yet, I'm interested. Of course "free" is a good price. (I wouldn't even think of charging you to haul it off.) On the other hand negotiation is fun, too. (703-641-8940)
It would be a long way to tip a rarey like yours, even if it does start (which I understand, it does)! These old Chevys are strong, but in my limited experience, after a few years sitting in a field, they can get...moody? Either that or your mechanic is every bit as skilled as you say he is.
I'm green to this site (isn't it wonderful?) myself too, but I've yet to see anything but a positive and polite attitude by everyone. Nairy a troll has announced its ugly presence to stink up the pleasant atmosphere. Good people, here.
