I just picked up my 427 SO from Keith Craft. When I ordered the motor, I told him that I would not be racing the car and that I wanted my power before 6000 rpm. He installed a mild hydralic roller cam that gives me 560 hp at 5800 rpm and 594 lbs torque at 4700 rpm. I will be running a toploader tranny with a 3.54 rear end. When I was specing the motor with Keith, I gave him all this info and that helped him placing the right cam for the right application for me. Now just have to wait on the car to put it in! Although it would make a great snowblower!
My cam specs are 248/252 .635/.633 3170B/3151B 110+4, not sure what all that means, but that's it.
To watch the Dyno of my motor, click on this link.

A decent 427 - not the worst, not the best, will go from zero to 100 mph and back down again to zero in less than 14 seconds. All thing considered, you can put together a pretty good argument that the 427 Cobra is the ultimate performance car, judged on any basis you want to name."
