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. It will spin the tires as long as I stay in the gas and that is with 13 inch tires out back and a 50/50 weight distribution.
