Power Steering and B/RB in a '72 Duster?

How much motor are you throwing at it? We've never had the 440 on the strip, but my best guess is that it will run a high 13-sec 1/4 mile. It COULD be quicker, but it has limited traction and 3.23 gears. That's plenty fast for a fun street car. By comparison my older son's 383/4sp/3.55 geared Barracuda has run a best of 14.08 in the 1/4 mile while being completely setup for handling.

Would they both be quicker with headers? Probably, but the cast iron manifolds fit better, leak less, and cause less heat in the engine compartment. It's really all in what you want out of the car and for me it's lots of torque in a driver. I really don't care what 1/4 mile numbers it will put up because it will likely never see the strip.
