    From what I've read, there's not a great difference in performance between them, but it depends on what you're looking for. If you want better take offs and more low-end torque, get the Performer. If you want more high-end torque, like for passing other cars, get the Performer RPM.

    Hope this helps.

    I have the RPM and I really like it. It has plenty of low-end for me and the better breathing up high is great on the highway. That's what you'll need for dune-running and highway stuff. Go with the RPM.

    I've got my dream truck and it's a 72 K-5 that is getting there!!

    I've used both on my trucks before. If you tow a lot or have dead gears use the performer. If you have tall gears and a stick or rev a lot use the RPM. there really isn't that much of a difference though. Both will work, for either application.........js

    The boys at Car Craft magazine have done some dyno tests to see how different manifolds compare. Even though it goes against all the other advice out there, they found that the single plane Edelbrock Victor Jr. gave up very little on the bottom end and had much more on the top end when compared to the Performer RPM. You might want to chat with the folks at Edelbrock to be sure you get exactly what will be right for your needs.
