Flywheel ID help

[dgswinger]

Can anyone help me ID this flywheel. It was sold to me as a 10.5” 360 car flywheel. I’m starting to have my doubts that it is for a 360. I know the number on it is the casting # Any help is appreciated.

Considering a 360 didnt come out until 71/72 and based on the casting numbers I’d guess it’s a 225/273 internal balance flywheel.
