What's your opinion between the 2 engines? And do you think it was a good idea on fords part to leave the 5.4?

 

What do you mean by...leave the 5.4?

 

the 5.0 is a stronger motor , but the 5.4 was built with towing in mind. for example a lot of the torque and hp comes on at around 2500 rpm while the 5.0 hp and torque comes a lil higher in the power band. Ford still uses it in the expedition and it gets around 16-17mpgs

 

Well.....there ya go.

 

The 5.4 is a dinosaur compared to the 5.0. 'Nough said. The 5.4 has zero advantages in comparison. Though the E boost gets all the cred ( I have one) the 5.0 is almost equivalent with the Eboost having a clear advantage only form the towing perspective. They provide almost the same MPGs in testing. If you want to save a few bucks the 5.0 is a fine choice. The 5.4 is something Ford probably wants to forget, badly outclassed by its rivals in the day and very inferior to the new lineup, thirsty and weak.

 

My dinosaur does have:

1. Enough HP and Torque to tow whatever I want that is towable by a half ton with a great torque curve for towing through the city.
2. Not terrible mileage, but not great
3. 15 years or so of history and development
4. easy to find and cheap after market parts
5. A great V8 sound that the ecoboob cannot match

My dinosaur does not have:

1. Random shudders at 55-60 MPH
2. Starting issues
3. Weird misfires depending on humidity indexes
4. The uncanny habit of going into limp mode at the most inopportune times.
5. Random leaks yet to be explained.
6. high 300's in the HP and torque categories- and I do admit I covet that a little.
7. The EPA ratings of the newer offerings, although I think many are quite surprised now with their real world fuel economy after their purchase

While I will agree with you- the 5.4 is technologically dated compared to the other two you have listed, I still think it is a strong engine, great for it's purpose as a pack mule, and still has life in it no matter what. When the 5.0 and the ecoboob start turning 300,000+ then I will agree they are far superior beyond the HP and Torque numbers. Incidentally- the 5.4 is absolutely not an inferior engine compared to the 5.3. Have you ever put the two side by side when really working them or towing? The 5.3 is more of a dog than any of them. Given the choice between the 5.0 and the hot water six if I were buying a new truck now? The 5.0 all the way- definitely an awesome engine.



TL; DR- don't hack on the old guy until you're absolutely certain he is good and dead, because he might be the one towing you back after all your great and wonderful technology breaks.

 

Take the 5.4, give it the high compression of the 5.0, the 4 valve heads like the 5.0, and an aluminum block like the 5.0, then you would have a strong lightweight 5.4.

The Lincoln Navigator 5.4 was built with 4 valve heads and made more power than the Ford 5.4.

Really there is no real comparison between the 5.4 and 5.0. They are apples and oranges different.

 

Since I have not driven a truck or car with the 5.0 I really can't compare. However there is one thing that I know is fact. The 4.6/5.4 engine is a long lasting tough engine. And for me thats all I need. I didn't buy my truck to run fast quarter mile times. I have an old Mustang for that with a true dinosour 5.0.
I work in downtown Chicago and the best example of these modular engines is all the old beat up Crown Victoria cab's running around. They all have over 200k miles, are not well maintained, and beat to he11 in the worst driving conditions possible. But they keep running and running and running. Nuff said!

 

+1

My dinosaur moves my 35's just nicely while still getting good MPG

 

I bought my 2010 FX4 a few months ago and love it. Could I have purchased a 2011 for a little more? Sure I could have. But I think the 5.4 is a great motor that has been proven time and time again. To say it is a dinosaur is lame. And after reading about all the issues with the EcoBoost I am happy with the decision I have made.

I bought my truck as a DD and to tow my Mustang with when I am racing. Not to race my DD.
