Edelbrock Performer RPM

I am the original owner of a 71 340 Duster, 4-speed. The car is street driven with just over 50k miles.
Currently, I have a Edelbrock LD340 manifold with a Quick Fuel carb.
What do you think the benefits of replacing the LD340 with a Performer RPM.
I am quite sure I'd have to find a bit lower air cleaned for hood clearance.

The performer RPM is a great intake, the best all around intake. You see an improve across the spectrum.

Your QF carb, the RPM intake and stock air cleaner will fit. Keep the hold down stud to the minimum length though. It will be a tight fit with the stock hood.
