What the hell, I'll chime in with my 2 cents...
The 5.4 has plenty of jam; it's all about where the engine is making it's hp & torque. And trucks are heavy. They need lots of torque down low. The 5.4 3v makes it all down low and in the mid-range, and makes plenty of it. And the rating is conservative as well. It'll be interesting to see how accurate Toyota's numbers are, and to see how it pulls in the real world. The 5.4 has nothing to prove; it does the job of a hard working truck motor just fine. The new Toy, well that remains to be seen. It may surprise us all. Then again, it may not...but don't bash the current 5.4 3v. Look at how piss poor the numbers for the Ford 300 cid 6 were. I'd still love to be able to get a truck with that engine. It's not all about the numbers, and people who use their truck for anything more serious than ego boosting know that.
Now that 4 speed tranny, that's another matter. Get the 6 speed already!! That will make a big difference.
