The Quick Time RM-6023 bellhousing connects a small-block or big-block Chevy Engine to T56 Chevy LS, T56 Magnum and T56 Magnum-XL transmissions. This bellhousing is S.F.I. 6.1 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)
