360 Interpretation

[ninet64]

I recently picked up a rebult 360. I was looking at the engine-stamping number on he drivers side,front of the block just below the head surface.
The numbers are 9W630 6651. I tried to identify these but it appears the engine series may have been stamped wrong as well as missing special information and production code. Can anyone shed some light on this, or point me in the right direction ?

Thank you for your time.

I'll take a stab at it:
9 = 1979
W = Windsor Ontario Engine plant
630 = 360 cubic inches either written down wrong, or Monday AM or Friday PM engine
6651 = production sequence
I don"t have my books near me right now so that is the best I can do HTH.

Looks like that casting day, Oct 21 1979 was a Sunday...
