Is there a big difference between the Edlebrock Performer and the Edelbrock LD4B?

Apperance wise,
a Lot, the LD4B looks like a stock intake.

The Performer has a lot of extra threaded holes.

The Performer is Not suggested for use on a 273,

I think the Performer will not flow well at low cfm,
speeds,whereas the LD4B is a Chrysler approved,and sold part,
that was made for the 273,and 318.
