Why would it be "better?

The inboard needle bearing was a mistake.

I'm with Cotten and Rammy why put another grenade in your motor. Also your present cam won't fit the needle bearing bushing it's journal will be about .002-.003 too small. The only advantage is you can run any aftermarket cam for a Pan as they are all sized for the needle bearing bushing which came out in 1957.
When I changed to my current aftermarket cam I just turned about .002 off the inboard journal and it fits fine in the solid bushing.

Well , I always seem to be diff. , but I had mine changed to the Torington bearing and have a lot of miles on it and no problems . Strange that these type of bearings are used on just about every thing now a days and you have pro's and con's for both systems, its your choice.

Needle bearings are much cheaper to produce than bushings, and need no skill to service.
The fact that a bushing won't frag on you means nothing to a beancounter.
