A727 Flexplate (360 Ci.)

The B and M AUTOMOTIVE A727 Flexplate for 360 cubic inch engines is a precision-engineered torque converter coupling designed for Mopar Torqueflite 727 automatic transmissions. This external balance flexplate accepts 6-bolt crankshaft configurations and meets SFI 29.1 safety certification, making it a critical component for high-performance and restoration builds where transmission reliability is non-negotiable.

Steel construction provides the rigidity and fatigue resistance necessary for sustained engine loads, particularly in modified applications where stock flexplates may fail under increased torque output. The external balance design requires matching with externally balanced crankshafts and converters—a critical specification that must align with your entire drivetrain assembly to prevent vibration, component damage, and catastrophic transmission failure. Weighing 3.8 pounds with compact dimensions (14.1 x 14.3 inches), this flexplate maintains OEM fitment while delivering verified durability through SFI certification.

This component is essential for builders, restorers, and performance enthusiasts working with 360 Mopar engines paired to A727 transmissions. Whether rebuilding a classic muscle car, upgrading a stock drivetrain, or replacing a failed flexplate, the A727 flexplate from B and M AUTOMOTIVE delivers OEM-comparable quality at competitive pricing. Verify your engine's balance type (external vs. internal) and crankshaft bolt pattern before purchase to ensure proper fitment and safe operation.
