Corvette engines have the last six digits of the VIN stamped on the block just ahead of the cylinder head on the right-hand side combined with a three-letter engine code suffix
Also cast into the top rear of the block is a four-symbol code indicating when the engine was built
The first letter of the date code shows the month the block was cast
The one or two numbers shows the month
The last digit shows the year
Engine suffixes: Code Engine Horsepower Compression Transmission Fuel Supply
