Not Ranked
The Coyote will be a nice, reliable, street performer. It will have impressive performance in the upper rpm range and excellent mileage - if that's important to you.
It will not have the low speed torque of a 400+ inch engine, but it will also not buck and fart in fifth gear with 3.31 gears on the highway.
If you want all the drivability of the Coyote and the instantaneous response to your ever so slight movement of the accelerator you need to put a positive displacement blower (KB or Whipple) on the engine.
In blown format you will easily have 580+ ft/lbs of TQ from a very low rpm all the way to redline - table flat and you have 650 to 680 HP for fun and games. As long as you keep you foot out of it you will see low to middle 20's for mileage depending on your tune.

after thoughts; These engines are not inexpensive to build. For that matter none of the engines we use are inexpensive to build but some find ways to become more expensive than others. A blown version of this engine fits somewhere between a side oiler and a SOHC price-wise, if you do it correctly - something to think about
