The Quick Time RM-6060 bellhousing connects small block Ford engines to a Ford TKX, TKO 500 or600, 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 lightweight while maintaining the protection you desire. Note: (Transmission Mounting Bolts Not Included)
