Description

The B and M AUTOMOTIVE Flexplate TF727 (383-440) is a precision-engineered flexplate designed for serious engine builders and transmission swaps involving big-block Mopar powerplants. If you're running a 383 or 440 cubic inch engine behind a TorqueFlite 727 transmission, this component is the critical link between your crankshaft and torque converter. Without a properly rated flexplate, you risk catastrophic drivetrain failure under load—making this upgrade essential for any high-performance or street/strip application.

This flexplate meets SFI 29.1 certification standards, ensuring it can safely handle the extreme rotational forces and shock loads generated by large-displacement Mopar engines. The TF727 designation confirms compatibility with the legendary TorqueFlite automatic transmission, which is legendary for durability but demands a flexplate engineered to match its torque capacity. At 3.56 lbs and compact dimensions (13.15 x 0.7 x 13.55 inches), B and M's design balances structural rigidity with minimal weight penalty. The flexplate's damping properties reduce vibration transmission to the converter while its bolt pattern and pilot diameter are precisely machined for 383-440 cranks, ensuring perfect alignment and zero runout during high-RPM operation.

Muscle car restorers, hot rod builders, and transmission specialists choose this flexplate when upgrading or rebuilding classic Mopar platforms. Installation is straightforward: bolt it to your crankshaft flange, check runout with a dial indicator, and confirm torque converter pilot fit before completing the transmission installation. Whether you're doing a 440 Magnum restomod, a 383 stroker build, or rebuilding an original driveline, the Flexplate TF727 (383-440) provides the reliability and OEM fit that discerning builders demand for long-term, hard-use performance.
