Reid Racing’s Super Hydra 400 (SH400) case is a two-piece design, while the standard TH400 is one piece. The SH400 has a removable bellhousing to allow different engine/bellhousing bolt patterns. Reid offers bellhousings for GM, Ford, and Dodge small-block engines as well as Buick/Olds and various big-block versions. The case mounting bolt holes all have steel-threaded inserts for strength.
