need help decoding a 455

Hi All,

I've got a chance to pick up a 455 block with 4 bolt caps
and HO 197 heads, but can't figure out some of the numbers on the block.

Cast is 485428 which I understand to be a 455 anywhere
from '71 to '74. The code is a YC which could be '70 or '73?
Above the code is C(or 0)087535. Number down the side of
the timing cover is 220(orD)3(or8)10800.

The date code is indistinguishable.

Any help from the decode detectives would be immensely appreciated.
