You've got enough converter to run a single plane like an M1 or Weiand X-cellerator but I'll bet the car/combo will still et better using a performer RPM or RPM air gap intake. Your right on the cusp but the cam lift duration is fairly mild so I''d stick with the dual plane WIZE World's Quickest Diahatsu Rocky (??) 414" Stroker Small block Mopar Powered. 10.84 @ 123...and gettin' quicker! https://www.youtube.com/watch?v=-mWzLma3YGI In Car: https://www.youtube.com/watch?v=PjXcf95e6v0
