How do you know if have a small or large flywheel in your Chevy 350 engine?

To tell if you have a small or large flywheel in your Chevy 350 engine, you will need to remove the starter motor. Once you have removed the starter motor, you can look at the flexplate. The flexplate is also known as the flywheel, and it is connected to the crankshaft. The flexplate has a ring gear around the outside edge. The ring gear is what the starter motor engages to start the engine.

The small flywheel flexplate will have a ring gear that is 153 teeth. The large flywheel flexplate will have a ring gear that is 168 teeth.

Here is a table summarizing the differences between the small and large flywheels:

| Feature | Small Flywheel | Large Flywheel |

|---|---|---|

| Number of teeth on ring gear | 153 | 168 |

| Diameter of flexplate | 14 inches | 15.5 inches |

| Weight of flexplate | 17 pounds | 24 pounds |

Additional Information

The small flywheel is used with engines that have a higher compression ratio. The large flywheel is used with engines that have a lower compression ratio. The heavier the flywheel, the more energy it will store and release during each revolution. This results in a smoother running engine.

If you are not sure which flywheel you have, you can contact a Chevrolet dealer or engine specialist. They will be able to tell you which flywheel is in your engine by providing your engine serial number.
