54l

I purchased a used 2008 F250 with the 5.4l engine.How can I determine if my 2008 f250 5.4L ford engine is E85 Capable? My understanding is that the main difference is the rubber fuel parts are limited because the E85 destroys the material.

my coworker has a harley davidson model but hes looking for a tuner... who makes a good one?.. which is a reputable maker?

best sounding muffler for my truck.? Also would i need to change my exhaust from a single to a dual? because i would like to keep it single if i can. also, does buying a tip do anything?

How about any other years? Have you gotten more mileage to the gallon? I am currently getting about 14 mpg. Will I get more if install the K&N kit?

light came on 2 days before.? I have not got the codes yet. Could this be something other than a head or intake gasket since it never ever overheated? Does anyone know if 99 ford 5.4 L's had a epidemic of bad intake gaskets?

I'm looking at getting an F150 and I'm just wondering how long the V8's tend to last in 97-03 model Fords.
