Single Plane or Dual Plane? The Great debate!

Have you ever tried a Stealth to see how they do on the dyno Mike? Particularly on strokers since you said they have larger runners

My Classic Cruiser 360's use them, they make good power 380/410. I have used them on strokers before, last one made 560/550 with a mild comp solid roller cam and a set of RPM's with a stage 2 port job.
