Please stop making such ludacris claims, that is a COMPLETE guess and all I hear you talk about is long tube headers in every suggestion this past week. No offense bud, but please stop posting false info.

I'm not trying to start anything just trying to get my point across in the best manner I can come up with. But, yes headers are a pain in the *** to even look at on these trucks, let alone change. But, more flow always will=more power and more sound!

Thats like saying more fuel equals more power, not the case in gas powered vehicles (it is in diesels, for the most part). There is a silver bullet to flow in the 5.4, and for N/A'd 5.4's the Maggie SISO seems to be the solution. You like to mention the flowmasters you recently put on (as I) reduced your low end, the reason is the lack of flow (in some mufflers cases), it's a damn box with resonating sound walls, not a straight-thru design like the maggie. If you look through the maggie you can see straight through it, the flowmaster, you can't. It's common sense on that aspect. Now as far as too much flow goes, if you did your own exhaust (can't remember if you did or not), when you had no muffler or piping connected behind the cats, you have a lot of popping because there was a strong lack of backpressure. Exhaust cutouts work the same way.

Like I have said a hundred times before, it's ALL about set-up. Think of it this way. If you own a Lariat, extended cab, 2WD, 5.4L then you are already at around 5300lbs empty curb weight (loaded options). Even the lightest config supercab model is 5244lbs empty. Not to mention that is sitting on 32.7" tires with (in most cases) 3.55 gears. What exactly do you think the performance is going to be compared to a Quad Cab Hemi, on 33" tires, 3.92 gears (much lower), 5 speed auto OD tranny (more lower gearing), 45 more HP, 10 more ft lbs TQ, and about 350 lbs less weight. BTW, a RCSB 2WD Hemi on 20's weighs in at 4700lbs. My RCSB F150 5.4L on 17's weighed in at 4925lbs stock as an XL with ZERO power options, no carpet, and tiny little 235 tires.

My point is to to think about it. Of course it's faster, the numbers dont lie. HOWEVER, dont let the 5.4L fool you. We are also WAY de-tuned from the factory. Shifting at 4900 RPM when we should shift at around 5300-5400rpm, tuned for 87 octane, throttle by wire is modest for maximum fuel economy, just look at the intake system (WTF?), torque modulation is tuned for crap.

Take a stock RCSB HEMI vs a tuned RCSB F150 5.4L with similiar gearing and you will win or break dead even depending on driver.

In my case, I beat him over and over again. Of course now I am supercharged and he doesnt stand a chance in hell.

Also, yes some of you supercharged guys are still in the 15's in your non-intercooled, 5600lb loaded beast. You didnt see that coming?

I am running a 6lb Powerdyne non-intercooled and I can run in the 13's all day. All hail the RCSB.

Second. Josiah, there is a big difference between shorty headers and long tubes with high flow cats.

Out of the box the Hemi and Vorteck, Nissan engines out gun the 5.4, who wants to spend thier $$$$ to improve Fords lack of design...The automatic is what hinders the 5.4...I doubt my engine will see 100,000 KM

i AM automatic

The advantage they have is the aluminum block and the ablity to mod as well. Your car with cams should run with a stock LS1 F-Body...anything other than stock and my bets on the LS1 (I have owned 3 LS1 cars so I know a little about them and they respond to mods very well).

Now as for LS2s (new Vettes and GTOs), LS6s (C5 Z06s) and LS7s (new Z06s)...well you will need a lot more than new cams to play with them. I say that because "LS" Chevies are not created equal!
