The engine code designation was marked on the block to aid the builders and stampers. They used this code to as a guide to assemble and stamp the blocks. I have a 16,000 mile 65 Corvette that clearly has the engine designation on both sides of the block by where the mounts are. You can read them through the exhaust manifolds.
