It would have been a bronze bushing originally.  A bearing can work.  I wouldn't recommend it as there is no benefit but if you must, use a  sealed, maintenance free bearing.  Reason being that you can't lubricate it regularly, as bearings require and if it seizes, it may damage the input shaft.  Been there, done that on another brand engine.

Since the inner diameter of the bearing doesn't turn on the input shaft it is prone to seize to the shaft, making removal of the transmission difficult. For this reason I prefer the bushing. Besides, there is no horsepower to gain from a bearing.

My preference is the bronze bushing.  I had a pilot bearing in my 427 Ford wtth a Top Loader and that bearing seized to the input shaft which made the transmission a bear to remove as the car had a scattershield.  The V10 in my truck came factory supplied with the pilot bearing and those were failing at 20K mile intervals.  The grease was essentially being cooked out of them.  I machined a bronze bushing to go in that spot and its now been over 80K miles without issue.
