5.4 vs 6.2?
Hey guys. I have a 2008 f250 with the 5.4. Love my truck, but considering getting a 2011 with the 6.2. Is there a noticeable amout of power difference? Anything to be aware of with the 6.2? Any input would be great!

Huge power difference for sure as well as a couple more gears in the transmission. The 99-07's are by far my favorites when it comes to styling, but the 11 will definitely give you more power.

I liked my 2000 5.4 when I had it.
It did everything I needed it to.
My 2015 6.2 though....no comparison. Pulls much harder for the same or less fuel.
I wouldn't sell a perfectly good running 5.4 just to get a 6.2, but if the 5.4 is tired, I wouldn't buy another one as long as I could afford a newer 6.2 truck.

I have not driven a 6.2 but after reading a lot about them I'm hesitant about getting out of my 08 5.4 as well. To me it seems that the horsepower increase comes from a loss of low rpm torque. The 5.4 won't win any drag races but one thing it does well is pull anything you put behind it.

At no point do they cross.
The VCT is different. The modular engines use a dual equal oil pressure actuated VCT mechanism, while the new 6.2L uses a dual equal cam torque actuated VCT mechanism.
