on some of the dyno's you guys run on,it probably is,,for others w/ more accurate ones,not so.I just did a 600 w/ 357 afrs and got to 740hp,of course I kept the lift .675" so the valve and springs weren't getting changed every other year.and the engine idles at 800rpm.

I work in an engine manufacturing facility with 8 certified engine dynos capable of handling a lot more horsepower than anybody on this board is making. With that being said, I can tell you from first hand real world experience that no two dynos are the same. Even from day to day things change.
