Do you know anybody with one of those flexible bore cameras, or whatever they are called? Might be able to get a view through the drain plug to see if the parting lines in the crank are thin (cast) or wide & flat (forged). Maybe even find a number on it.
It might depend on just how it was balanced if rebuilt as well. Internally with mallory metal, with OEM weight parts or aftermarket, etc. Might need a counterweighted flexplate too if its all not "neutral". Bore scope - not a bad idea. I think I know someone who has one. It's a 4-speed and I'm told that the car should have a 10.5 inch flywheel with 2-holes drilled all the way through the flywheel next to one of the flex plate mounting bolts (thanks Wayne from Brewers!) since its a V code and should have the heavy rods. I will check for that also.
