Have Both in half ton.  Hemi has way more power but pulling anything gets 8-12.  5.4 less power by far IMO and way better at 15-18.  If you drive like an old lady one time I got 21 with the Hemi.  I willl never drive that slow again!

fisrt problem with my 5.7 was a broken valve spring at 240,000 miles. at 240,000 it was down 1 quart in 3000 miles gas millage is ok as long as you keep your foot off the floor.

Talk to a guy yesterday that has a 5.7 in his 9000lb service truck and he can't believe how much more power it has then his 5.4 half ton pickup. He said he was really impressed.

My mother has 06 Dodge 3/4 ton with Hemi, it has lots of power about, 14-16 miles to gallon, and my cousin has both the ford with 5.4 triton and dodge with Hemi and he always pulls the trailers with the Dodge so it must pull better, both are 3/4 tons. Terry

I like the 5.4 for a its flat torque curve. The triton has enough hp to do the job the 1/2 ton is designed to do, but definetly less then the Hemi. "Hemi" and "Fuel Mileage" should never be in the same sentence. The tritons are decent on fuel for a V8, I think the 5.3L chevy has a slight advantage in fuel mileage.

I have two 5.4's in 1/2 ton supercrews. One is an 04 and one is an 08; both are rated at 300 HP. The difference in the power between the two pickups is unreal. The 08 will walk away from the 04. Driving 60 mph and anticipating stops and bringing it up to speed slow, I've got 20 mpg many times with the 08. Of course this was country driving without a lot of big hills. Driving the 04 the same way. will result in 1 1/2 to 2 mpg less. Neither of these pickps pull much, but I once had 13,700 lbs behind the 08 for 100 miles. It pulled it all right, but for sure not like my 7.3 diesel.

As for the Hemi, I have no experience with it.

I take the Ford motor any day. Fords are well known for there low end torque , longevity an reliability. Hemis are over rated IMO.

Sounds to me like if someone changed the rear axle ratios the Hemi would get better mileage, maybe not as much power as it currently does. Might be a good compromise.

I just got back from a fishing trip. had an 06 ford 150 with the 5.4 pulling a 14 foot v nose wheel house and got 8 mpg on the nose. We have an 06 dodge 2500 with the hemi. last year I pulled an 18 foot steel livestock trailer to Fargo and back and averaged 10.5 mpg. Not completely comparable, but we do love our Hemi. Lots of power and the mpg is a lot better than the ford we had. Guess I've never been that impressed with Ford engines, but I did like the rest of the truck.

You are funny. Yea, it may outdo the 5.4 but it sure as heck isn't anything to brag about either.

There you go. My thoughts too. Like the rest of the pickup but that engine would make a nice boat anchor someday.

8mpg here with it with a flatbed loaded with tools and an empty fuel tank on the back. Power.......eh........ what power? I would like to also know what torque I was reading about above? They must of made some major improvements over the 01 model year. I can pull a hat off your head but thats about as far as I'd go with it.

24 foot stock trailer with 4 atvs in the back and it can't even maintain a hill climb at 55 mph? Sheesh..... I think the ole GM 305's would do that with a 4 barrel and they were a true blue boat anchor with rotten fuel mileage.

I'm on my 3rd 5.4 in a pickup and always thought they're a good balance between power any mileage. Avg is 15, maybe get 17 on a long trip in the summer. Not bad for a ¾ ton pickup.

The 5.4 is now out of production. Ford is working on the 2011 pickups. The new engine is around 400 cubes but nobody has one yet to try out.

Pa, If you would do me a favor. Would you please weigh your foot and then get back to me?

I am still trying to figure out why I have such rotten mpg with this pickup and alot of others have good.

Is yours a half ton? I'm using a 3/4 for comparison.

I still want to know how much your foot weighs. :-)

That's on a F-250 ¾ ton. I had a '99, a '02, and now a '10. All are/were the same on mileage.

All had the 6 speed manual transmission too. That fancy automatic shifter will cut them back.

First I would like to ask... Which one is bigger? Of course the 5.7 is going to have more power, its a bigger engine. However 5.4's are a pretty bullet proof engine I don't know much about the 5.7's pulling anything, everyone I know that has one just use it to get groceries. I always give them a hard time and say its because that is all the truck can handle for weight.
As for you Rich, ever change the air filter? or fuel filter? Maybe that's why you experience poor mileage and the lack in power...
