From another forum:

"The 1111263 is the highly prized “Ball Bearing” distributor. This was a heavy duty version initially released for the reverse-drive camshaft 427 big block racing engine. It has a special ball bearing on the upper part of the mainshaft instead of the usual bronze bushing. It also has an iron housing with a mechanical tach drive and a special reverse-drive distributor gear that permitted normal clockwise rotation of the distributor in this special 427 engine. It was specified not to have a vacuum advance. (The plate inside the distributor was fixed in position.) This distributor listed for $1,699.05 in the 1991 Chevrolet parts books! I know of several Corvette guys that would love to have a chat with you!!"
