68 F4 ....on rear of block not sure about the 68, but the concensus is F4 would be the form number for the casting.
35M121464 .... below head on drivers side it's a 1975 engine that came out of a car manufacutred on the Lansing MI assembly line.
396021Fa GST .... on front of motor 455 casting number. The "a" indicates that it's the revised block used from 1973-1976.

Any help is appreciated!

yeah, I figured its just a smogger motor which is ok, as It's just going to be a cruiser, motor runs good and doesn't smoke at all so I think I'm going to drop it in my 68 ragtop. Should still make some good torque though. Thanks for the info.
