Intake Manifold Q & A


Ken Westerlund: Anyone running a Edelbrock Performer RPM manifold? I am thinking about changing from a stock four barrel to the Performer RPM and I want to know if I am going to loose any bottom-end torque or MPGs. The engine is a stock 440 with dual exhaust and a mild cam.


Bruce Blum: You may lose some low end and idle smoothness with a Performer RPM...its power band starts at about 1500 rpm's. You will gain top end with it. With a 440's natural torque you may not notice any change with the new manifold.

I have a 383 with a standard Edelbrock Performer and Edelbrock carburetor. It's essentially a stock intake made of lighter aluminum. I'm quite pleased with how it runs, but I don't run it for competition, just smooth running.
