The 6 cyl. hydra-matic actually has sort of an adapter plate between engine and trans. I know that there were some hydramatics in Oldlmobile, Pontiac, Rolls Royce, Cadillac, and others. I don't have any idea if a bellhousing is available for a modern smallblock bolt pattern. The other problem might be a flywheel that is actually front part of torrus housing as well as a starter. If you decide to do away with the trans for something more modern, I may be interested in picking up a spare hydramatic if it is for a torque tube driveshaft. Actually even the 261 if same circumstances you decide you need a more modern driveline.
