    Well, I didnt get to dyno my motor because it is below zero here and the cold air intake on the dyno here comes from outside. It is going on the dyno the 21st of this month if nothing else unexpected comes up.

    My guess is 410 uncorrected horsepower peak. The calculation is pounds of fuel per hour divided by the Brake specific fuel consumption right off your dyno sheet. That is the observed horsepower, before the sea level correction that the engine is NOT doing on the dyno.
