the Moroso slide rule shows 9.56 @ 140.2 for 775hp and 3650lbs.


to put it in persepctive, my buddies 3850lb 68 Charger made around 750hp on our dyno.
car has run 9.71 @ 139.5.

Moroso slide rule shows 778hp for the 9.71 ET, and 802hp for the 139.5 speed.

if the HP numbers are real, and the car is fairly well sorted out, and you're not running in crap air, the Moroso slide rule is generally pretty close.
