The original block was so broken and rusty it was beyond repair.
The block in it now is one of the last cast in the third batch and is a true 623 '61 block. Oddly enough, it has a VIN on it (which wasn't done in '61 production). The VIN belongs to an Atlanta '62 Chevy!
I interrogated the engine thoroughly through Butch after he bought it from Lamar Waldon.
The unique parts of a '61 409 are entirely interchangeable with the parts of later 409s, and vice-versa.
