That number shows up as '61-'66 car or truck 283.
What you want is the suffix code
that was stamped into a boss at the front passenger side of the block where the head meets the block. This can give some indication of what the engine was originally installed in.
There were no differences in blocks used in 'Vettes, trucks or passenger cars, other than the suffix in MANY cases.
