Reid Racing's bellhousings are cast from high-strength 6061 T6 aluminum and are heat-treated for additional toughness. These bellhousings pass stringent SFI 30.1 certification and are approved with no external shields required. The bellhousings feature 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. No special flexplate is required. They come available for the Reid Racing Superglide and Super Hydra 400 transmissions.
