My '69 427 is a stock 390 HP motor. I had it dynoed at Carlisle two years ago. It showed rear wheel :
248 HP and 350 FT.LBS. of torque.
I am led to believe that those numbers are fairly accurate due to the fact the 390 rating is a gross rating and you lose about 15-20 % to the fly wheel and another 15-20% through the drive train.
With that being said, my '93 LT1 (300 net) should actually have a higher rear wheel HP figure than my 427.
The 427 seems a heck of a lot faster due to the much higher torque.
