A Super T-10 would be a good choice behind the Olds engine. You'll need a bellhousing, maybe could find and OEM one, or Lakewood still makes scattershields. Then, a flywheel, clutch, pressure plate, pedals and linkage, or a hydraulic clutch slave cylinder and pedal would probably be easier and cheaper in the long run. Oh yeah, and don't forget the pilot bearing for the end of the crankshaft.
