Heads should be Std. '68 360, 390, 428 (68 to 71 CCV). Block is alot harder to identify C8ME indicates it could be a 428, '68-'70, but trucks also had the same ID. My book says 390 IDs don't have the ME with the prefix C8. The suffix A indicates it's a orginal design meaning no changes. If you can you need to look at the crank, flywheel or flexplate. 428s were externally blanced and they have a thicker flywheel/flexplate with a counter weight attached. A 390/352 flywheel don't have the weight. I think the 428 std crank forging number was IU. About all I can do for you.
