SBF To P/G Ultra-Bell 164 Tooth

The SBF To P/G Ultra-Bell 164 Tooth flexplate adapter is engineered for small block Ford engines transitioning to Powerglide automatic transmissions. This specialized bellhousing assembly bridges the gap between two incompatible platforms, enabling engine swaps and transmission conversions that would otherwise be impossible. Fabricators, hot rod builders, and performance shops rely on this adapter to maintain structural integrity and proper fitment when pairing classic Ford powerplants with the durability and simplicity of Powerglide architecture.

Constructed from aircraft-grade aluminum, the SBF To P/G Ultra-Bell features SFI 30.1 certification—a critical safety standard that ensures the bellhousing will contain internal engine components during catastrophic failure. The 164-tooth flexplate design accommodates high-revving small block Ford engines while maintaining proper balance and engagement with Powerglide transmission internals. The natural aluminum finish resists corrosion and allows for straightforward integration into custom engine bay layouts. At 23.15 pounds, this ultra-bell minimizes rotational mass without compromising durability or structural rigidity.

Street rod enthusiasts, drag racing teams, and professional engine builders benefit most from this adapter when executing small block Ford to Powerglide swaps in vintage vehicles or high-performance applications. Installation requires careful alignment with the transmission tail shaft and securing fasteners to manufacturer specifications. The SFI 30.1 certification makes this component mandatory for sanctioned racing events and insurance-protected builds. Compatibility is strictly limited to small block Ford engines with 164-tooth flexplate applications and Powerglide transmissions, ensuring proper torque delivery and longevity in both street and competition environments.
