[QUOTE="ModularSpeed, post: 8423666, member: 56332"] DOHC heads cost A LOT more. More material, twice the valves, twice the springs, twice the everything. The 2V head design is excellent. In the past the NPI / PI 2V heads were not designed very efficiently, so the power potential is not very good...in n/a form anyhow. You take a redesigned OHC 2V head, and the sky is the limit. 3V and 4V of course can even be more efficient, but the cost is crazy. Ford knows they have to be pushing ATLEAST 375 HP with their next platform on the GT's, and their best route is to stick with a smaller, high revving engine to accomplish it. There are a lot of downfalls to mass producing a 6.2L engine to put into many different vehicles. The OHC design is efficient enough to only utilize 300 or so CI to make "competitive" power (around 400hp) If and when the 5.0 DOHC engine comes out...it will probably be around 375HP (detuned) and 400HP with an "aggressive" tune (an aggressive tune to Ford, is seriously lame) If you follow the past results from almost any performance car(engine).....most will easily lay down the same amount of power they come rated at, at the rear tires with bolt-ons /tune. A 400rwhp bolt-on Mustang will be pretty serious with some gear. [/QUOTE]
