    Rated 3 out of 5 by from Works but! The flywheel works great for the application I am using it with but seems like you might have to shim the flywheel for the starter to work but over all it's a nice flywheel and is preforming great!

    I have a Chevrolet 350 HO crate rated at 333 hp. It ha a one piece rear main and requires an externally balanced flywheel. Is this flywheel made for the 305 only?

    Asked by: In need of a Flywheel
    Yes, we have other flywheels for the 350 engine with a 157 tooth bellhousing - https://www.jegs.com/i/JEGS/555/601250/10002/-1

    It appears from the backside that it is concentric. What I mean is, I can't tell where it was offset balanced. All the other "external balanced" flywheels I've seen have material off to one side. Am I missing something here?

    Asked by: Camaro Bob
    It may be hard to tell from photos but the left side of the flywheel has more material removed than the other. It is for an external balance application.
