79 440 in a 67 dart?

I believe they made 440's in 79 but they only came in motor homes. Have you ever taken your car to the strip? And do you have any numbers on what kind of power and torque its making? Im just worried about getting a motor that even if I build it that its not going to make any power.

I installed a 440 in my 71 scamp, pump gas motor with 10.1 compression. Edlebrock RPM package. Makes 500 HP on the dyno with 535 FT torque with the Shumacher headers. Runs 12 flats with the mufflers on. Hope this helps you out.
