The assembly code would be stamped completly on a long block just as it would be on an engine to be used in a vehicle. There were a number of crate engines with the assembly code and date code that were sold that did not have CE stamped on them. The red/red 1967 L88 Corvette coupe that is a well known car has a correct L88 long block with an assembly code perfect for the car. This engine was found at a Chevrolet dealership with no CE, just the engine code and engine designation stamped on it. It could have just as easily gone into an L88 Corvette but it went to a dealer parts inventory. In this case, the owner chose to install the engine in the car that needed it and not stamp the VIN portion of the number. He wanted to leave the original L88 crate motor undisturbed.
