You will need to change out the bellhousing, as the bolt pattern is different. The 292 uses the same bellhousing as the V8. You'll need a bellhousing from a '55-'72 V8 or '63-'72 6 cylinder. The front mounts will have to added as well. There are kits available to mount a V8 on th side mounts to the frame (not the crossmember style) that could be adapted to this fitment. You should be able to use your existing trans just fine.
