If you were told that your small block Chevy engine was swapped or rebuilt, here’s a quick guide to help you identify exactly what is in your vehicle.
First, locate the driver’s side just behind the head where the bell housing or the transmission bolts to the block. You will find a numeric code like “14010207” that indicates the generic block and the area it came from.
On the passenger side, in the engine block area below the alternator and right above the water pump, there will be a flat surface with a casting number stamped on it. This number provides specific details about when and where the engine was built.
To get more information about your engine, you can simply use your preferred search engine as the information is widely available online. By using the casting numbers, you will be able to determine the exact specifications of your small block Chevy engine.
