Thanks. Got an answer on the Engine forum finally that shed a little more light on it also. It re-confirmed that it is a 305. And yes, the date code is Oct 7, 1977.

Tells you just can't trust any seller what so ever. He told me it was a 350 out of a 87 Chevy C20 4x4. Funny how GM used 10 year old engines in the new 1987 Trucks. Also didn't think too many '87 C20 4x4's came with a 305. I might want to save this engine/ truck combination. It might be a pretty rare production number.
