The Ford 2005 F-150 series of pickup is a favorite choice for those wanting a truck with not only a powerful engine, but also a reliable one. Reliability is what Ford always strives to maintain and the pickup's F-150 engine has proved its dependability.　

The F-150 engine has been produced in different sizes and installed in the different models of the 2005 Ford F-150 series. F-150 engine sizes produced are the 4.6 liter V8, the 5.4 liter V8, and the 4.2 liter V6. Both V8s have automatic transmissions, while the V6 model has automatic or a five-speed manual. The power differences between these three engines are quite remarkable.

The F-150 engine for the 5.4 liter V8 is equipped with three valves per cylinder, a unique variable cam system, as well as a slew of other add-ons designed to give the engine the power needed for an array of different heavy tasks. At low speeds this 5.4 liter V8 engine is very powerful, seemingly taking advantage of its state-of-the-art engine design and extras.

The F-150 engine has been ...
... improved over the years & is now a lot quieter and a great deal more fuel efficient. This 5.4 liter engine is capable of punching out 300 horsepower at 5000 rpms and also has a 365 pound/feet of torque at 3,730 rpm. That's a lot of power and proves the engine is capable of a variety of heavy jobs.

If we now compare the F-150 engine for the 4.6 liter V8, then the difference is clear. The engine comes with the same bells and whistles as its big brother, namely cams and valves; however it only manages 231 horsepower at 4,750 rpms. Not to be totally outbeaten, the 4.6 liter V8 F-150 engine is capable of delivering a 293 pound/feet of torque at 3,500 rpm. This kind of torque coupled with strong acceleration, is ideal for towing heavy loads. This vehicle with its fuel saving features, would be the perfect farm hand. The powerful F-150 engine runs on standard unleaded gasoline and because of the aforementioned fuel efficiencies won't have you pulling into a gas station every time you head out from home.

Let's move to the next F-150 engine within this group of quality pickups and learn about the 4.2 liter V6 F-150 engine. Again this engine, like the V8's, has an array of cost saving extras added. As mentioned above, Ford, for the first time, has given the buyer a choice of transmissions - either manual for those who love four on the floor, (in this case, five on the floor) or an automatic. This smaller cubic capacity engine is capable of thumping out 202 horsepower at 4,350 rpms and will impress you with its 260 pound/feet of torque 3,750 rpm. Again the V6 model of the Ford F-150 engine pickup truck is a vehicle to be worked. The Ford Motor Company gave great thought to the design of the F-150 engine for the V6 model, as the pickup lives up to its reputation as a workhorse, albeit reliability.

These three different engines were designed for different jobs in different environments. The V8s are no doubt capable of doing almost any task with vehicle gusto. One must remember, however, that although both vehicles have the same F-150 engine, their cubic capacities are different and thus the type of workload differs.

About: The junior V6 with its F-150 engine is a vehicle that I would recommend for the home handyman or gardener; its lighter V6 engine is more than likely more cost saving and thus cheaper.
