The Quick Time RM-6060LHS bellhousing connects small block Ford engines to a Ford TKO 500-600, TR3550 or T5 Mustang (standard length input shaft) transmission. This bellhousing is not S.F.I. certified which is required by many sanctioning bodies for cars running 11.49 or faster in the quarter mile. This bellhousing is a universal fit bellhousing and is not vehicle specific. The Quick Time bellhousings are produced using a unique spin forming process which results in a very high strength material. This high material strength allows the Quick Time bellhousings to be light weight while maintaining the protection you desire. Note: (Transmission Mounting Bolts Not Included)
