SLB8SNK... You are certainly entitled to your opinions just as the rest of us are. I've witnessed a stock 5.4 against a 6.2. I can tell you who wins. The 6.2. Hands down. No Question. But not by as much as you might expect. (Hell, not by as much as
I expected!)
Each powerplant definitely has it's advantages and disadvantages.
Try running E85 in your 6.2 (please don't, you'd probably damage it!) The ability to run E85 is an advantage for some. Just as for others, they much prefer gasoline or don't have access to E85 so the 6.2 has the advantage of more power without using E85.
One thing I heard over and over at the Roundup (and TEAMFORDRAPTOR even mentioned part of it on these forums) is that the 5.4 "handled better" on the track than the 6.2. The most common comment regarded the perceived greater tendency of the 6.2 to "nose dive" on a jump. Other comments were regarding handling in the corners... the opinion was the extra weight of the 6.2 engine was the reason.
On the other side, it seemed unanimous that the 6.2 felt more responsive. As far as the claim that the 6.2 felt so much more powerful to most there? Not my experience. Either truck was capable of going way faster than safe on the track with very little throttle. Two of the Ford Corporate reps told me that on that track, they truly believed it would be hard to tell the difference between the power of the engines for
most people.
This list of differences could go on for pages.... But what it all comes down to is what is important to you may not be important to me! And when you look at it that way, maybe you'll notice there are several significant differences between the two engines other than the 6.2 advertised peak power numbers are higher.
<sigh> So go ahead and bash away. Tell me I'm crazy and I don't know what I'm talking about. I'll respond in advance: What I've said in this post is based on my real-life experience. Not "numbers". Not "0-60 results" taken months apart under who knows what differing conditions. I'm not a salesman trying to talk someone into a more expensive option. And the truth be told, I'd LOVE to have a 6.2!
But comparing a 5.4 to a 6.2 is simply NOT like comparing a Mustang 5.0 to a GT500! Not even close! And that's not my opinion. That's my EXPERIENCE.
YMMV.
