"5.4 liter really only has a longer stroke than the 4.6"
....and that longer stroke makes it alot faster in quarter mile. Or any other "start-off" situation as well as in torque.
Think of it as a comparison of 2 bicycles. One with long pedals and one with short pedals. You could start off much faster on the bike with the longer pedals and could pull a heavier load easier as well.

The 4.6 I had before the SC was much faster than the 5.4. Oh, wait, maybe that's because it was a Mustang!
Seriously, I test drove a 4.6 and a 5.4 SC, and there really is no comparison. The 5.4 pulled much harder out of the hole and throughout the power band. I didn't buy mine for racing though, I got it for the pulling power. My bro-n-law has an Expedition with a 4.6, and it only took him 3 weeks after an attempted towing trip for him to start wishing he had got a more powerful engine. Luckily, I was able to benefit from his revelation and I was sure not to make the same mistake.
But that was an Expedition. The 4.6 is probably much better suited for towing in an F150. I just didn't want to take any chances. The little extra gas it uses concerns me, but not nearly enough for me to regret my decision.
Good luck.

My brother in law has a 97 4.6. I drove it alot before buying my 99 5.4, there is a BIG difference in power. To me, the 5.4 is better from a stop, has much better mid range acceleration, and I won't even compare the two for overall towing. It all depends on what the truck will be used for. If it is just a daily driver with trips to Home Depot on Saturdays, a 4.6 would be OK. But, if you tow and want the extra power, the 5.4 is the one.

Go with the 5.4l without a doubt. I had a 97XLT xcab 4x4 with the 4.6 and it was way underpowered. Now I have a 99Lariet Xcab 2wd with the 5.4 and WOW what a difference. Granted the 97 was 4x4 which made it a little heavier but man that 5.4 kicks butt and I am seeing about the same gas mileage.

Referring to the first post-----
Doesn't the guy with the SC 5.4 weigh in about 1,000lbs more than the guy in the Reg. cab 4.6???
I guess I am suprised that everyone is saying he will get smoked?
I would think it to be a close race (gears being equal)
Now I wish I would have gotten the 5.4L
Oh wait...I just remembered that this is only a truck and I could care less. Just race him and let us know how it turned out man!!!!
