4V technology is superior if fully implemented.
With a SOHC engine like the 4.6L, 3V the same cam runs both the intake and exhaust valves. This means that when you vary the cam timing you are changing both the intake and exhaust timing together.
With DOHC engines that have separate cams for both the intake and exhaust valves you can independently vary the intake and exhaust valve timing. This allows you to vary the intake and exhaust valve overlap which can be used to dramatically reduce emissions and also to really improve the torque curve.
Ford is way behind on this. BMW, Porsche, etc. have been selling DOHC 4V engines for years that have independent variable timing on both the intake and exhaust valves for years. If Ford implements this on the 4.6L, 4V engine they'll have something. But I'm not holding my breath as from what I've read the Duratec35 does not have dual variable valve timing.

DEARBORN, Mich., Dec. 12, 2005 – For the second consecutive year, the 4.6-liter 3-valve V-8 that powers the Mustang GT has been named a "10 Best Engine" by Ward's Auto World. Ward's testers again praised Ford for creating a refined V-8 that produces 300 hp at an affordable price and called it “a convincing modern-day interpretation of a muscle-car V-8."
"Going into its second year on the market, the new Mustang still is the hottest car on the market, thanks in no small part to the 4.6-liter V-8." said Barb Samardzich, vice president, Ford Motor Company, Powertrain Operations. "We are quite pleased that, for the second year in a row, Ward's has chosen to recognize Ford Motor Company for this engine."
For 2006, the Ford Explorer and Mercury Mountaineer are also available with a 4.6-liter 3-valve V-8 engine. The 3-valve technology in the 4.6-liter V-8 offers improved power coupled with better fuel efficiency and reduced emissions. Other 3-valve engines in Ford’s modular V-engine series include the 5.4-liter V-8 in the Ford F-series, Ford Expedition and Lincoln Navigator and the 6.8-liter V-10 in the F-series Super Duty.
The 4.6-liter 3-valve V-8 is built at Ford's Essex Engine Plant in Windsor, Ontario, Canada, and at its Romeo Engine Plant in Romeo, Michigan.

Probably too much $ for too little performance.

Unless plans have changed, there is only going to be a minimal h.p. increase with the Bullitt. I would love to see 400hp, but I doubt it will happen. I think we will have to wait til 2009 or 2010 before we start seeing those increases.
