Phillyc, "Paritied" is the key word here for engines, they will all be dyno'd and made to conform to identical HP/Torque and delivery specs.

The thing we need to keep remembering is they will not allow ANY mechanical advantage to exist.

Simply there will be no advantage for choosing 1 engine over another other than build costs. Honestly i cant see a race ready Coyote costing less than the current OHV engines given the significant extra number of parts and virtually zero R+D to date.
