I compared it to a Holley Strip Dominator and it was a bit slower. But due to the higher limits of the combo (converter, gear, cam duration, etc.), I wasn't surprised.

If you do some tuning with the Stealth, try 2 #s difference between the left & right sides. The deeper side plenum liked to be 2 numbers richer than the shallower side. (...or 2 #s leaner in the shallow plenum, depending how close you are to optimum to start with.) This was with a 1" tapered 4-hole Canton phenolic spacer & Holley 750DP. Car ran several hundredths faster and plug color was more consistent. A-B-A-B testing same day.
