Cobra Make, Engine: Keith Craft built my monster 527 Shelby, Rob Camp @ KCM in Plano, TX installed, tested & tuned it and Dean Rosen @ Dynamic was magnificent in delivering my dream SPF #1857. Without these guys, I'd never have realized my dream.

A 10-20 horsepower or foot pounds difference is certainly understandable.
Maybe a shootout in the future would be a good thing, but I surely would think a fairly quick run of the same motor on two different calibrated dynos would resolve any doubts in the near term.

I'll certainly agree that the differences should be minimal and calibrated dynos should provide like results. However, there are lots of different dynos and different ways to do a dyno pull. A set of restrictive headers on a dyno can make a 40+ hp/tq difference. If everyone is not 100% certain of the legitimacy of the environment, the outcome will be meaningless.
Kudos to Brent who I think put the whole sorry subject in perspective.
