454 Flexplate

The B and M AUTOMOTIVE 454 Flexplate is a heavy-duty torque converter mounting component specifically engineered for big-block Chevrolet engines with 454 cubic-inch displacements. This flexplate is essential for those building street machines, restoring classic muscle cars, or upgrading existing drivetrains, ensuring reliable power delivery and longevity.

Designed to absorb shock loads and compensate for minor misalignment during power transfer, this flexplate employs precision engineering to handle the extreme torque output characteristic of 454 big-block engines. Its structural rigidity balances minimal rotating mass, which helps reduce parasitic inertial losses in the drivetrain.

Ideal for anyone upgrading or replacing a worn factory component in 454-powered vehicles, this flexplate accommodates standard torque converter bolt patterns, ensuring repeatable installation and minimizing vibration or transmission shudder under load.
