Does anyone know the difference between 5.4 5.0 and Eco. Just my own curiosity. And I wonder if the springs in te front are different.

Ecoboost - 416.7 lbs
5.0 Liter - 435 lbs
3.7 Liter - 335 lbs
6.2 Liter - 580 lbs

Don't know what the official weight is for the 5.4

There are different springs, but they're not based off the engine.

I have been wondering the same thing. Found a post on a mustang board stating 835lb for a sc 5.4 . I was thinking that springs from a 2010 fx4 with the 5.4 might boost the front of my 2011 0.75 to 1inch. 5.4 was an iron block so it might work. need more info though.

No way according to that guy the 6.2 iron block weighs less

I got the weights from the 2011 F-150 Workshop manual

I'm assuming those weights do not include the turbos and related piping/intercooler?
