5.4 3v vs 5.4 2v
I've got a pretty bone stock F150 and all my other friends in town have the 5.4 2v Superdutys. I won't race my truck head's up because I'm too young to be getting outrageous speeding tickets. Anyways they say that their Superduty's would just kill my truck. So for all the 04,05,06 F150 owners, who would win the race?

Hmm I don't know about that. Consider the parasitic loss in the drivetrain. the "300 HP" 5.4L puts down 240 HP real world in a 4x2 truck on a dyno. So the same percentage of loss in the F250 4x2 would yield 208 HP. There of course would be more loss if the trucks are 4x4. I am not questioning your honesty but it is extremely hard for me to believe that a truck with 208 HP on the ground and weighs more can beat a truck with 240 HP on the ground that weighs less. If the F150 was a Screw with 3.55 gears and the F250 had 4.10s then it would be understandable. However, if they are similarly configured the F150 is going to win. I'd love to see them both run in a race though. Maybe you could get a coworker to race you in your truck, for research's sake?

Stock for stock, the 5.4 2V superduty worktruck I drive will own my 05 5.4 3V, I have no reason to be biased.
I've raced my dads F-250 SCREW SB 5.4, killed him, both had 33s at the time even though mine were about 1.5" wider.

Before I sold my 2000 F150 with 5.4 2v (basically same truck as my 04, supercab, 4*4 etc-see sig), I thought I'd race my new 04 cause the butt dyno was telling me my 2000 would destroy the 2004. After the race I had a new appreciation for the 04 cause it destroyed the 2000. The 04 feels slower for some reason, but is actually faster. Weird, but true, maybe its the quietness or the smoothness, I dunno.
As for the superduty, you will kill it. I raced a F350 PSD from light to light up to about 60mph, I lost, but only by half a truck length. A 2V F250 wouldn't stand a chance. Go shut em up.

My F-150 won in my case. I raced an F-250 with the 5.4 (super cab) no idea of gearing or anything, and pretty sure it was stock, I got up to about 90 or so and almost had to wait for the guy at the next light ( a good bit of distance between us anyway). My 4x2 screw has the 3.55 LS and slightly larger tires (265/70/R17 dueler AT Revo's). The F-250 was also 4x2. So I think we've got the edge on them at least.

I raced my buddies 03 with the same gears I've got from about 15mph to about 80 and I walked off and left him from the get go, we did another race from about 40mph to 80 and I pulled him by about 1 truck length. Both of are trucks were stock supercrew fx4 except his had an magnoflow exhaust and my was factory.

Maybe the initial jump on the older 5.4 2V makes it seem faster, either way Im not racing the work truck, the trans just took a dump with only 100k miles. The company will be distributing new trucks soon so Im curious as to what I will get. That'd be cool to get a new F150, but seriously doubt I will.
