If you have the 4.8" large register hole big block 1970 bellhousing you can use it. You will need the input shaft bearing retainer off a heavy duty "308" bearing A833. The O/D A833 uses the same "308" bearing for the input shaft but the register size is 5.125" and there is no factory big block bellhousing in that size. You can also use a quicktime bell or other aftermarket with the 5.125" register hole.
