This has been debated before, time to bring this back up!

5.4l has my bets. Faster, stronger.

When I drive, I'm usually in the 1500 - 3500 range. How do Chevy owners drive when peak torque is at 4000? The Triton is a workhorse and Ford sacrificed some mileage to get the torque, I think I can live with that.

I have driven both. My cousin has a 99 5.3 reg cab long box Z71. The Z will haul ***. I think chevy makes up for what it lacks in low end torque with gearing, as well as engine managment. The chevy revs very quickly and is not affraid to wind out gears. I think they are basically tit for tat, with the chevy being a little quicker. Ford is definately the better truck as far as quality, and I would much rather pull my horses with the ford. There is something satisfying about being able to get a 13,000+ GCVWR rig up to speed staying well under 3,000 rpm and it is even more satisfying when you can do it with only 330 cubic inches, of course that's just my opinion I could be wrong.

If you like to go off-roading, you will like the low end torque of the 5.4L it really helps get up steep hills, mud pits, turn big tires, etc. I have a 351W in my current truck and I love the low end torque that it has. The mid range is nice too, just not to much after 4500 rpm but I never go past that even when im racing someone. so who cares about high end power in a big truck. Well if its a lightning I do, thats about it.

The Chevy truck engines seem to be car engines.

 

I agree with that, fast. The compression ratio is pretty high as well, I'm surprised that it can still take 87. The triton almost seems to be a 'diesel' (long stroke) version of a gasoline engine.

Longer stroke in the 5.4, anyways.

(forget h.p and toruqe)If one 5000 lb vehicle will out accelerate another 5000 lb vehicle don't you think the one that was quicker was more powerful?

faster46 what is the difference between a car motor and a truck motor. the 4.6 in the mustang gt, cobra and the 4.6 in the truck all have the same bore and stroke.

 

Just curious, why would you want to forget about horsepower and torque? Without these two peices of the pie, you go no where, no matter what the brand ... Your post is redundant ...

nitrox, i'm courious what part is redundant, I posted 1 time on the subject, metioned h.p. one time, metioned torque 1 time, and used used the word powerful to descibe the feeling. after a chevy spanks you from a stop light do you catch him at the next stop light and tell he can't do that because you have more torque.
by the way, don't i need gas, tires and a whole lot of other thing to make my truck go?

 

Brotherdave Man you just dont understand! OK lets try this race: 1999 Ford f150 vs 1999 Covrette: stoplite to stoplite OK?
On your mark, get set, GO!

But now..... which engine would do better towing a 5,000 lb trailer? and dont pick the Corvette either.

Please see your other posts 4.6 vs 4.8

michael_hovis-
I don't know about "ALL" the 5.3L trucks, but my boss has a Y2K Z71 and it requires premium fuel just like the LS1-equipped cars.

BrotherDave-
The block is about the only common thing between the versions of the 4.6L engine. The entire "top-end" (TB, upper/lower intakes and heads) as well as the exhaust are all totally different between trucks and cars. Plus, the Cobra has a DOHC engine.
