it seems like you have enough gear for the little 340.
So I would change to the regular rpm intake. Don't get a rpm airgap, as they don't run well in cold climates. Your carb needs heat under it to run correctly. Just use the exhaust restrictor. Get a square flange intake.
what are the cam specs?
how is your ignition timing setup? initial, total mechanical, how much vacuum advance?

|daveh||The car runs great but I am changing over to a shaker hood and I'm not certain the hood will shut. It's a Tremec TKO600 5 speed. It a posi 3:27 gear. Weight would be an issue for the intake the stock one is heavy compared to the RPM. Which I like. If it won't give me any gain then I won't do it but even if it's a little I will do it. Thanks again|

sounds like it is heavy.
automatic? what gear ratio? (highway gears?)
how does it run now?
how about a 440?

The stock intake will make more torque under 3500 rpm.
If the car is heavy (4000 lbs +) and has a low numeric gear (less than 3.00) then you will be better off with the stock intake.

Stock 340 intake or Edelbrock Performer RPM
I'm finishing up assembling my engine and I want to get a new intake. It's a mild 340 in my 71 Dodge Challenger, 30 over, purple cam, forged crank, 2.02 1.94 heads, etc.
I have a stock intake. I am running a holley 650 double pumper and I am using the adapter plate on the stock intake for the square bore Holley. I want to get as much as I can out of the engine and don't know if the cost of the Performer RPM would be justified and be a better improvement. I am going with the Performer RPM because I think it will fit with the shaker hood. What do all of you guys think? Thanks for all of your help. Thanks
