The one I mentioned was on the stingiest of three dynos in the area, and the 2bbl Sportmod motors are going on the same dyno. You haven't seen any difference in power output with different fuels, carburetors, timing, or headers? Believe it, don't believe it, whatever works. Maybe all the dynos need to be checked.
