I was just watching Motorweek (great show!) and was wondering something. I owned a 1997 Ford F-150 with the 4.6L V8 a few years back. Motoweek was covering the 2010 F-150. This year, it has the following engines: 4.6L V8 (2V per cylinder) 4.6L V8 (3V per cylinder) 5.4L V8 (3V per cylinder) Ford had a 4V version of the 4.6L and 5.4L in some a few car applications (Mercury Marauder, Mustang, Lincoln Aviator, Lincoln Continental, Lincoln Mark VIII). Why not the truck engine? I would think this would be an easy way to implement a power bump and MPG bump in a new model.
