The sound is also unique with a deep V-8 burble. Ford doesn't claim any more power for the Harley, but I think they are not telling us everything. This thing feels like it wants to fly. Nailing the go pedal from a dead stop will cause the F150 Harley to scramble from 0-60 in 8.02 seconds. I had two runs in the 7.7s, very quick for a nearly 5,000 pound sport truck.
Throttle response is immediate and the truck feels powerful and athletic.
And that's with a very low 3.55 limited slip axle. With 3.73 or 4.10 gears the Harley would run deep into the sevens to 60. But the 3.55 is the right choice for economy and flexibility giving the Harley the ability to run near fifity in first and an easy 80 in second. The sound emitted from the exhaust is sweet, but a 70 mph on the highway, the engine slows to a very relaxed 2,000 rpm with a very muted wonderful murmur. There is nothing like a smooth, great sounding V-8.
