I got everything back from the machine shop. The crank was a 1968 318 truck steel crank, notice the small harmonic balancer. Turns out that the new pistons with the 273 rods we put in were a little lighter than the crank was originally balanced for. Now that everything is balanced it is back together again. Crank was drilled at the rear to accept the converter prior to being balanced. Now that everything is bolted back together here is a shot of long block on the dolly with the K frame, trans, headers, steering box, dist and plug wires almost ready to go in. I have a few more odds and ends to finish before I bolt this in as I don't want to have to lean over the fenders any more than I have to. I posted some other pics on the restoration forum of the dolly and the engine. Thx to everyone for the advice.
