About this part

Product Details

If you're swapping a modern LT1 T56 transmission into a classic Chevy with a small block V8, you'll need the right flywheel to make it all connect. This aluminum flywheel from SPEC is designed specifically for that popular conversion, allowing you to mate your V8 engine to the LT1 T56 gearbox. It's a crucial piece for getting that project car running smoothly with a more modern drivetrain.

This flywheel is built from strong, lightweight aluminum, which helps reduce rotational mass. Less mass means the engine can rev up and down more quickly, giving you a snappier throttle response. It's designed to work with a 2-piece rear main seal small block Chevy engine and the LT1 version of the T56 transmission. SPEC makes sure these flywheels are well-balanced and machined to tight tolerances so you get a solid connection between your engine and the transmission, which is key for smooth shifting and long clutch life. You'll want to make sure you have the correct clutch kit that matches this flywheel and your transmission for a complete setup.

When you're putting together a custom swap like this, getting the right components is essential. This flywheel is a well-built piece that addresses a specific need for Chevy enthusiasts looking to modernize their classic vehicles. Make sure to consult your transmission swap guide for any specific installation notes or hardware requirements to ensure a successful build.
