Thanks for all the feedback, everyone. Here are a few pictures if it helps. Unfortunately, I didn't take any of the Engine compartment and I didn't have time to check the partial vin on the radiator support. But I'll do that and try to get a vin off the motor itself when I go back. If it is a clone (which it sounds like is the case), it would be nice to know if the motor is at least a real, period correct 340.
Any thoughts on what a fair price would be for a clone, assuming it's has a real 340, A833, and 3.23 posi?
