The Quick Time RM-8023 bellhousing connects Holden 308 (Trimatic and Turbo Pattern) and 304 V8 engines to T56 Chevy LS, and T56 Magnum 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)
