Buick/Olds/Pontiac bellhousing for the Reid Racing 2-piece Superglide and Super Hydra 400® is not a dual-pattern bell, which allows for a perfect fit to all Buick, Oldsmobile, and Pontiac V8's without unused bolt holes and awkward castings. Cast from high-strength aluminum and heat treated for additional toughness, the bellhousing passes the stringent SFI 30.1 certification* and is approved with no external shields required. The bell features an open bottom for easy converter access, a reduced diameter for better floorboard clearance, and a contoured mounting flange to properly match the rear of the engine block. Starter pockets on both sides allow for driver or passenger side starter locations. No special flexplate is required.
