The 460 flywheel had casting # RF-D9TE-6380-BB with a cast oval with a 253P in the center also on the flywheel surface.
It has some stamped letters that read
E7TR-AA D on a flat machined area near the outside edge.
If you have an 11" clutch you have a 351M flywheel, not a 400 flywheel.
And...if you have a 11" clutch, the engine may not be a 400, it could be a 351M.

not offer the 460 with a manual transmission or with 4WD until 1983.

400M / It's just plain 'ol 400.
