I see by the vin it was assembled at Hamtrack so I also posted the info on B-Bodies only site. It would be cool to find the original owner but I know that's high hopes
Found 340 block, casting numbers 2780930 340 3
Serial number GW340P33980190
Partial Vin 1B310745
I also have the heads from this motor, 1 J head and 1 Z head
Just throwing it out there in case it can find it’s way to the original owner
