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.
