Thanks for the responses! I love the older truck.. its a 99 xlt super cab.. coming from a 06 lariat supercrew loaded.. it was horrible. sweet looking but horrible driving. now, if I can just get some new wheels I would be doing good.

What I like about my 4.6 is I don't have to worry about cam phaser issues of the 5.4. A friend of mine has an '03 screw FX4 with the 5.4. I have driven it a couple times and have to say my '01 4.6L felt a lot more powerful. Granted his truck was stock and mine wasn't but I didn't think I had enough extra performance to actually best his truck. Had CAI, dual exhaust, underdrive pulley and hypertech programmer. Probably was mostly those 4.56's I had installed though. 
3.31's with 35's = horrible.

2v 5.4 doesn't have the cam phasers... It's pretty rock solid and if you torque to spark plugs properly you don't have to worry about plug blow outs

Only in the U.S.A would a 4.6 liter v8 be called "small/little".
It's too funny to see guys referencing their "little 4.6", gotta love it.
Hopefully your driving is better than your spelling.
