Give me your opinion 4.6 vs 5.4 F-150

[HidalgoGT]

mike just to give you a heads up my 02 f-250 crew 7.3 only gets 21 empty driving around town, it might not be as much over kill as you think and the turbo sound makes it all worth while.

My brothers 00 F250 with a 5.4 gets 13 highway lol. Diesel power .

I haven't thrown out the F-250 yet, I'm on a short timeframe though as my cobalt has to be turned in 10 days. I would love me a turbo. Thanks for all the help homies.

I have an F250 superduty with a 5.4 in it. I am very happy with it, decent power and I have managed a best of 17.5 MPG in it with 33" procomp xterrains on it. It's is no race car, but it isn't a turd either.

Drove an '09 STX 4.6 3V with 3.73's today and I'll tell ya what it was pretty damn close the the 5.4 with 3.55's

My 08 F-150 has the 5.4 w/3.55. I get 12.5-16.5 MPG. Winter mileage sucks. Its in the 15.5-16.5 range now. I think the 5.4 is the best option. Better torque/hp. Mileage is rated about the same/

The Lincoln has the 3V 5.4L and it won't get out of its own way, although it does tow very well. Can't imagine how much of a pig it would be with a 4.6L.

I've got an 05 reg cab/long bed with a 4.6. I've loaded this thing down with building material, rocks, scrap, moved everything from one house to the next and it's been fine. My biggest complaint is the 3.55's, great for the highway but horrible on hills. I've thought about doing 3.73's, I'd rather go 3.90 but it depends on how long I'll keep it. Also never had a injector stick or a plug pop out

My harley truck has a 5.4 in it, and its slow as all hell..... i can't imagine what it would be like if it had a 4.6..... however, if the 4.6 offers significantly better fuel mileage, i'd take it! Although, I don't haul anything more than a 220lb motocross bike in my truck!
