A833 OD or 727 behind a 440. Suggestions and questions

There may be a way to do it with a bearing in the torque converter snout recess and shorten up the input shaft accordingly. I don't think the factory ever put a manual trans on a cast crank big block. All the cast 400 and 440 cranks I have, and all the other ones I've seen are not drilled, but I have never seen a 318 crank that wasn't... cast or forged.
