The moroso chart shows about 355hp based on ET.
Speed is a better indicator for power, but you didn’t say what that was.
For a typical bracket type car, unless there is something pretty far off on the combo....... the car should run within 10% of the dyno numbers.
So, if you were in the 90% efficiency range......about 395 STP corrected hp to go 11.70@3250lbs.
If the car is really good, the numbers will show better than 90% efficiency.
And if the car is really really good...... it can actually run better than what the moroso chart predicts.
Even in pretty mediocre air my friends Stocker shows better than 100% efficiency.
