Did anyone make the jump from the old 5.4 to the current 4.6 3v with 6 speed? I'm wondering how comparable the power is when towing and get-up-and-go. What about mpg?

I'm really wanting a Ecoboost, but it will be a while before I can afford one of those, so I'm looking for something to get me by for a few years. I'm currently looking for something in the sub-$20k range and I can't find any 5.4's for that price that aren't completely stripped down models.

 

I went from a 2007 5.4 F150 to a 2010 4.6 F150. The 6spd tranny is great and the power seems to be about the same. You will not regret the 4.6, the only reason I would get the 5.4 would be maybe if I towed BIG loads all the time but even then I would look at an SD. mpg's are a little improved. Get up and go is about the same.

 

The 4.6 3v puts a stock 5.4 2v to shame, the only thing that keeps the 5.4 competitive is the lighter body.

 

I went from a 2005 short box / regular cab with the 5.4 liter 3 valve automatic (4 speed) and a 3.55 LS rear to an identical 2010 except it has the 4.6 liter 3 valve and the 6 speed automatic with a 3.73 LS rear. The new truck will flat out run away and hide from the old one. I'm perfectly happy.

BTW: The 5. 4 liter 2 valve motor? Not even close.

 

I'd LOVE to see a drag race between a 09+ 4.6L 3V and a 04-08 5.4L 3V (with the same cab/bed/drivetrains to keep weight/comparisons as close as possible).

Next year I'll be purchasing a truck so I am curious. My thought is the 09+ 4.6L would win.

I'm also curious how much (if any) a 09+ 5.4L would pull away from a 09+ 4.6L 3V.

 

Like I stated, from my personal experience with two virtually identical trucks, it wouldn't even be close. I like my 4.6 so much better than my 5.4 for many, many reasons. And yes, I do tow with it. The difference in towing a 4,500 pound boat and trailer is almost insignificant.

 

I had a 2007 F-150 Supercab 4X4 5.4 3V,4 Speed auto,3.55 LS axle all stock it ran a best of a 16.653 at 83.231 mph in the 1/4 mile.I now have a 2010 F-150 Supercab 4X4 4.6 3V,6 Speed auto,3.73 LS axle all stock also and to my suprise with only 750 miles on it ran a 16.257 at 84.89 mph in the 1/4 mile

 

Interesting Mark... while the 4.6 in my truck has noticeably less torque than my old 5.4l it sure does spin out better. Feels like it has a wider powerband.

 

X2,Less torque but seems to pull harder and higher in the rpm range.

Later Mark.

 

The two extra gears make a huge difference.
