Ford Updates 5.4L V8 In 2009 F-150
The 2009 Ford F-150 is getting a much needed update to the 5.4 liter V8 engine. Ford will be increasing the horsepower (if only by a little) of the V8 by using the ‘open valve technology’ fuel injection process. You can expect the truck now to punch 320 horsepower instead of 300 and from 365 lb-ft. of torque to 390.
The technology injects fuel into the cylinders while the intakes valves are open (normally they’re closed). In addition to the updated 5.4L V8, we also expect some Eco-boost powerplants to drop in the F-150 soon, though whether or not they debut with the new 2009 model isn’t known.
