I'm running a Performer RPM with a one inch spacer at the moment. I'll most likely end up swapping intakes later this summer as a test just to see how she works with a single plane intake.
The engine runs like a beast with the Performer RPM but I don't have 8 02 sensors so I can't tell you if I'm having distribution problems or not.
look at all eight spark plugs now before changing the intake, they will talk to you Isn't to much power almost just right
