340/360 Drivers Exhaust Manifold ID?

It’s a 68 340 motor, X heads and original intake. In the context of where I got it, it seems out of place with the exhaust manifold and spool mount motor mounts, there’s nothing like that there at all. The son I got it from has no clue where it came from or what it was in.
Greg the motor you showed has a car pan on it.
