This is a warranty replacement engine. There are several decoders for the block numbers for these engine on the web and all require the block serial # as well as this code.
The block casting numbers are on the top driver side of the bellhousing flange at the back of the engine. The engine code is stamped into a pad on the block deck in front of the passenger side cylinder head.
Chevy small block V8 engine numbers can be found on a flat surface area on the front passenger side of the engine block just below the passenger side cylinder head.
on the right side of the block where the head meets the block in the front is a small flat shelf and have numbers stamped there and a salvage yard could help you out with numbers
