SBF Flexplate - SFI- 164 Tooth- 50.5oz.

The SBF Flexplate - SFI- 164 Tooth - 50.5oz is a precision-engineered flexplate designed for Small Block Ford engines paired with automatic transmissions. Built by SCAT Enterprises, a trusted name in high-performance engine components, this flexplate serves as the critical link between your engine's crankshaft and torque converter. Whether you're building a street machine, resto-mod, or high-revving race engine, a quality flexplate is non-negotiable for smooth power delivery and transmission longevity.

This 164-tooth flexplate features a 50.5oz weight rating, optimized for balanced power transmission without excessive inertia that could affect throttle response. The SFI certification ensures this component meets Society of Automotive Engineers safety standards for rotating components, a critical requirement for engines running 10-second quarter-miles or faster. The two-piece construction typical of quality flexplates reduces vibration and accommodates the slight flex needed to absorb engine harmonics while maintaining precise torque converter engagement with your automatic transmission's pump.

SBF (Small Block Ford) platform builders—whether upgrading a 289, 302, 351W, or similar displacement engine—will find this flexplate essential for any automatic transmission swap or engine rebuild. The 164-tooth configuration is standard for Small Block Ford applications and ensures proper starter engagement and ignition timing accuracy. Installation requires engine removal to access the crankshaft flange; torque specifications and proper alignment are critical to avoid vibration, noise, or transmission damage.
