LD340 or RPM Air Gap

A recent test of several Mopar intakes by a car magazine showed the LD340 to still be a very good performer, however the RPM Air Gap had better horsepower and torque numbers across the whole range.

Now the question is,,,
How well would your 340 respond to the intake swap? Most likely with the parts (cam, carb and heads) that your 340 has, the increase would be worth the cost and effort. An RPM Air Gap is a very nice performing intake.
