The Quick Time RM-6074 bellhousing connects Mopar big block engines (383, 413, 426 wedge, 426 Hemi, and 440) to Ford TKO 500-600, TR3550, and T5 Mustang transmissions. This bellhousing is 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.
