Rick is right, ahead of whether its a bearing or bushing, the bellhousing needs to be dialed in as close to 0 as possible. When I built my Hurricane I started with a brass bushing and it seemed a tad resistant to fast shifting. I had the engine/trans apart at 1500 miles to fix a rear main leak and decided to install a roller bearing. With no other changes it made an enormous difference in terms of smooth shifting. My notes show Federal Mogul 303SS. Check that before taking my word for it.
