Is connecting rod bushings needed?

Are there any advantages/disadvantages to running the pins like this without the bushings?
I mean, I guess it takes bushing failure outta the equation, anything else?

when i had my 440 done for my valiant my machinist said the reason he wasn't using a bushing is that a lot of guys think the connecting rod gets too thin when opening it enough for the bushing.

my 440 was in my valiant and then in my demon. both were street cars first and logged quite a bit of street miles and i never had an issue.

these days old school still works but then again there are a ton of off the shelf parts for this stuff that is light years stronger and lighter than the old school stuff..
