2. Engine casting number: The casting number is a series of numbers stamped into the engine block. This number can be used to identify the specific engine model, including its displacement. The casting number for a 327 engine is typically "3918370," while the casting number for a 350 engine is usually "3970010."
3. Engine displacement: The engine displacement can also be determined by physically measuring the engine's cubic inch (CID) displacement. The CID of a 327 engine is 327 cubic inches, while the CID of a 350 engine is 350 cubic inches.
4. Cylinder head design: The cylinder heads of a 327 engine have a small combustion chamber, while the cylinder heads of a 350 engine have a larger combustion chamber.
5. Spark plug location: The spark plugs on a 327 engine are located on the side of the cylinder heads, while the spark plugs on a 350 engine are located on top of the cylinder heads.
6. Distributor cap: The distributor cap on a 327 engine has seven terminals, while the distributor cap on a 350 engine has eight terminals.
