It's 53-55 Chevrolet 235 maybe truck maybe car, I have the same block in my shop right now. Just above GM on Mine is 10 , The Cast date on the rear of the block by CON 4 or Con 3 . My Block is H 16 4 which is August 16 54

Yours is Nov 30 53, It would have been in a 1954 production car or truck. It's more than likely a truck block, If it was in a Corvette you will never know as someone has changed the build code on the dist ramp.
