Smile 2004 Engine 5.4 or 4.6?

I am buying a 2004 F150 Supercrew next month and can't decide on the 5.4 or 4.6 engine. I am not pulling anything heavy now but might need the power later and the gas mileage is the same on both engines. Any thoughts on the new 3 valve technology on the 5.4 or the current 4.6? Is it worth the $800 dollars for the 5.4?

2004 Engine 5.4 or 4.6?

From what I've read, quite a few people have said that the power increase for the 5.4 is negligible due to the increased weight of the new trucks. Following that logic, it would seem the 4.6 would perform worse.

IMHO, you'd be better off getting the 5.4., but I suggest you test drive them both and see which would better suit your needs.

Thanks! It seems like I should go with the 5.4 because of the added weight, but the engine is not proven yet.

If it's any consolation a few big wigs are driving the 2004 to make sure it's ready. Must have a lot of faith in their engineers. LOL

Go 5.4 even if you aren't going to be towing alot. I have 135,000 miles on my 4.6L 97 Supercab and I always wish I had the extra power. My 04 Screw will have it.

2004 Engine 5.4 or 4.6?

Not sure if Ford has their head on right sometimes, The 4.6 offers no mileage advantage over the 5.4, so im not sure why ANYONE would want this engine in their truck, I have one in my EXPY and PERSONALLY would like to shoot the guy who came up with the Idea for putting such a puny motor in such a large vehicle.

Lets Hope the new 04 is more ready then their hot to trot turblow diesel that they cant fix.

I am definitely going with the 5.4, for the one time cost it will be well worth the increased horsepower. I hope the tested the you-no-what out of this new 3-valve technology.

Honda has used the 3-valve technology for several years without any bad problems, so Ford should be successful as well.

One nice thing about the three valve technology is that there are significantly fewer moving parts compared with four valve designs. Fewer moving parts means fewer things to break, so...

2004 Engine 5.4 or 4.6?

I would definitely go with the 5.4 liter because of the sheer weight of these new trucks. Even if you don't do any towing or hauling you still want to be able to get up to speed and merge with traffic without too much effort. My current ride is a 97 f150 supercab with over 150k miles on the odo and although I never tow or haul anything on a daily basis, the truck could use more power for passing.

Not a good comparison imo.

Ford has no plans to put a diesel in the F-150's (heard it on a Ford conference call available on their web site). A reporter asked and they said no.

The milage on the 4.6 and the 5.4 is teh same according to the info I've seen. I'm definitely going for the 5.4 for whatever more it costs up front. It will be worth it.

The 4.6 gets the same mileage because it has to work harder than the 5.4
800 bucks is definately worth it to have a bigger engine. It'll probably last longer too, since it won't have to work to its capacity all the time just to get up to speed.

2004 Engine 5.4 or 4.6?

I tow my 19' boat with my 5.4 and my dad's 4.6. The 5.4 does a much better job at acceleration, pulling, less kickdown due to more torque, better traction (open vs. limited axles). The 5.4 does get worse gas mileage when towing, but for the gains in performance, its the way to go.

I believe the 5.4 is standard on the '04 FX4 and the Lariat
