Opinion from some of you long time Mopar racers

After making some jet and valve lash changes ran a best of 10.49 @ 122 this past Saturday at New England Dragway. Finally seeing what the car is capable of!

Is that MPH correct? If so, that's barely over 400 HP.

If we use your ET (which I never do) that puts you at a paultry 450 HP.

Something isn't right. Your MPH is down for your ET and that tells me it's down on power.
