I would rather have the 4.6L 2V. Unfortunately, Ford doesn't offer many F-150's that still use the old 2V. For this reason, in a new truck, I'd have to say 4.6L 3V.

 

Yea. Is there a specific reason why you would choose the 4.6 over the 5.4?

 

any specific reason? i know the new raptors have the 6.2

 

true that haha

 

A lot more power from both the 5.0 and 6.2.

 

I just tend to trust it a bit more. The 5.4 is probably just as trustworthy, but I just tend to think the 4.6 is more reliable. Think about this: The 4.6L engine is what they use in taxis and police cars. Police cars are constantly idling, accelerating from a dead stop (high RPMs), and just put under a lot of stress and abuse so they have to be tough.

To be completely honest, I also favor the 4.6 over the 5.4 because I like being different! Besides, if you know how to work on your engine you'll get just as much out of it as the 5.4 (but I must admit the 5.4 still has the more potential.) If you pull up to a guy with a 5.4 at a stop light and beat him to the next light with your 4.6, you'll feel twice as good!

 

yea true that. that would make sense, but arent they getting rid of the 5.4 and the 4.6 for those? i heard that from someone saying that the 5.4 is no longer being made its the 6.2 now and same with the 4.6 which is the 5.0.

 

you know, i never put it that way. that is a fact about that haha. yea i have a 5.4 but i have just heard some stuff about the 4.6 thats why im trying to see what the major difference is. but that puts a whole new perspective on it. and yea my buddy said that if i get a chip for a 4.6 it will beat out any 5.4(stocks). But that does make alot of sense the strees and constanly idling. you know they have to be good motors.

 

The 5four is a better motor all around, - hands down. If you new the engines well enough, you would have surely came to that conclusion.

Put 5000 lbs on a trailer behind a 4six and 5four. Now race em. - That's the difference,- half throttle will beat the 4six @ WFO. The purpose of the 5four to begin with. - It's not a taxi cab or a cop car, -it a worker and does it with ease, one that will last along time if you take care of her.

 

That's a mighty bold statement pilgrim.

The 5.4 doesn't get the same MPG's as the 4.6. I would go as far to say that the 2 valve 4.6 is more reliable than the 2 valve 5.4 due to the 5.4 having such a long stroke while the 4.6's being nearly square.

As long as you're talking about performance, then yes, the 5.4 is the best all around.

 

Absolutely jbrew! Cant kill a 5.4.... Just turned 260k on old faithful today and cant bring myself to get rid of her...Been way to good to me...She's towed more and had more in the bed than a 150 EVER should have, and not one engine or tranny prob! plus it helps that i just installed a new pair of westin stainless steps and a gibson supertruck catback kit...

 

Hell , my 98 5four had better mpg's than my daughters 98 4two lol. Driven normally, the 5.4L and 4.6L can get identical mileage, give or take very little.

The only significant difference depends on who's working the go pedal or when demanding power from the two engines. With the 4six, you'll get what it has. With the 5four you'll it what it has, but with that low end torque and power difference that 5four has over the 4six, - sure, it takes more fuel when called upon.

Driven normally, the 5.4L takes much less effort to go with the flow than the 4six, there isn't much difference at all as far as Mpg's.

 

Mines the same way, @ 272,000 miles. I worked the hell out it for years, - it's always pulled it's weight. I guess the most surprising is that it has NEVER used oil or leaked it. The engines never ticked or made other noises, - it's still just as solid as day one, - or better. I think it's finally broke in.

 

yea true that about more power but my friend can hull a 21 foot boat behind a 4.6L. and if I hull anything, im not hullin anything bigger than that. the most i pull is a little trailer with 2 fourwheelers on it. and i have a 5.4 and yea its a good truck and i know it will last long it has over 100,000 miles on it. but it is a gas guzzler and a 4.6 gets a little bit better mpg's

 

Well, their both Gas Guzzlers to NowADay's standards lol. You don't purchase a truck for their economy. Just know, if everything is up to par on maintenance with the two different engines, you'll net the same Mpg's give or take (a little).

To get a 5.4L in your truck when ordering new, it cost a little bit more and as far as residue value, - yes it's worth a little bit more. You can't take away economy from the 5.4L over the 4.6L because it just doesn't exist, not under normal/average operating drive cycles.

With the 5four, it's just there, - there when need it. You don't think twice about when it has to preform. That's the extra you get and sure, it will like the fuel then, -it's a give and take. Make sense?
