No, this is a motor for SS/Modified. Pretty much all of the dome and smallest combustion chamber and still getting enough valve relief gets you in the 15:1 range. I currently run the 2.3 Ford single cam engine but am in the process of building a Duratec motor which is an Ecoboost without the turbo.
