In stock form both will be governed by the top speed limiter. If you remove the limiter the 5.4 will have a higher top speed. Stock the 5.4 will accelerate faster. Bigger motor more power etc....

I had mine over 100 mph one time, it was on a downhill straight run in the mountains, and when I looked down and saw the speed, it scared the hell out of me! Prior to that it was pretty cool!

I don't know exactly how fast i was going but i would guess i have had it up close to 130mph on a few occasions. It'll pull all the way through 3rd gear, shifting out at about 5000rpm, and then pull a few more hundred rpms in overdrive. I don't really like stretching it out much like that....i know its not safe but i gotta let the truck "stretch its legs" some times.

if i had bigger tires or a taller rear gear i might could get higher, but i have had mine wound as much as it will go and it did 122 on a GPS, 97 4.6L full boltons, 26 inch tires, stock 355 LS

Ya somebody told me that my truck would shut down at 98 m/h too..well that person was wrong..all factory and i had it at about 110 when i finally gave up. The spedometer only goes to about 95 but then it goes a lil further so i was guessing 110 because i let off the gas and the tack stayed stuck for a lil bit. Takes a while to get up to there too when its hilly!
