Still going on and on with that nonsense? Comparing an older 5.4 Expedition 4x4 to a brand new yet stripped down 2WD Chevy work truck with a 6.0, and then complaining the Expedition didn't have as much pep? I wonder why?
Give me a PI 5.4 over a 5.3
anyday.
I am comparing it to 3 300 CI inline six ford engines and a 98 chevy truck with 350 vortec.
Well, see, I too have "extensive experience" with both the 300 I6 and the Vortec 350, and sorry bro, but the PI 5.4 is stronger than either. The fact that you think the I6 compares to the 5.4in anyway reallys shows how out of touch you are on this issue.

The 5.4 is a turd plain and simple.
If the 5.4 is a turd, then I would like to know what the GM 5.3, Vortec 5.7 and the 300 I6 are.

There are video tests on youtube comparing the big 3 and toyota and nissan all with the biggest engine offerings in 1/2 ton trucks and when it comes to power the ford was dead last in all the power tests.
Well see, now you're comparing the 5.4 3V to engines that outpower your beloved 6.0. Ever play with a 5.7 Tundra? The F150 remains the heaviest half-ton.

The 3 300 cube inline 6 engines we owned would pull like a raped ape. The 4.6 and 5.4 are both very weak.
Pull what? The 300 I6 with a 5-speed manual had good low end torque, but that's it. These things sucked pulling loads on the interstate. Oh yea, and they were slow. Yes, I've been there and done that as well. For a magazine racer, I find it odd that you refer to the 300 I6 with 11+ second 0-60 times as "pulling like a freight train". Seems like you have shifting criteria.

Fine for driving around but not good with weight behind it. The 350 old school vortec with a whopping 255hp never struggled once to pull my race car or our landscape trailer (thats what we do every day for a living). So dont you dare come on here and try to make it look like I have no clue what I am talking about. Like I said we have been there and done that and thank god we dont have to use the expedition to tow wil very often.
A PI 5.4 will outpull and outrun a Vortec 350 anyday. More power, more torque, every bit as responsive, comparable low end torque and FASTER in comparably equipped trucks. I've seen 1999-2003 RCSB 2WD 5.4s doing 14.9s stock. Frankly, you
don't know what you are talking about.

When ford went mod motor they couldnt deal with the lack of power and every last one of them switched to GM trucks and never looked back.
All Mod motors were not created equal, and once the PI cylinder head came out the 350 Vortec took a back seat to the 5.4.

I swear to god on a stack of bibles. These sheet metal guys are also hard core ford guys (old fords. They have over 35 of them) and even they told us if they were to buy a new truck it would be a GM.
Being sheetmetal guys, you would think they would recognize the far inferior
sheetmetal of the GM trucks.

Face it the LSX stomps all over fords mod motors. Why are ford guys so quick to defend them when they know they are wrong? I even said in that post that the mod motors are famous for long service life. They just dont make that much power.
That's funny, I made 354 rwhp with a stock h/c/i n/a 4.6 and just last night had my way with a two cammed LSxs.
