New lightning questions...3 valve heads?
What do you guys think will happen in regards to the new 3-valve head design ford is going to put on all the 5.4L truck engines. I would think for cost cutting reasons and performance reasons the new lightning scheduled for 05'ish? would get these heads? Is there any confirmation they will use 3 valve or 4 valve heads? If they do use 3 valve heads + the twin screw supercharger on the concept what kind of power gain are you looking at? From what i've read they got 500/500 out of the 2 valve head design with the more efficient supercharger. So could we expect 530-550? I would expect them to drop the boost down some but would still have that extra potential when we mod them?
If everything goes as planned i will be going to iraq in about 6 months to work atleast a 2 year contract and make 6 figure income+ for those years and then come home. I will be in the market for the new lightning when i get back thats why im asking questions now.

I have asked a very similar question and the response I got was that the Lightning concept has 32 valves and I believe that was the setup which produced 500/500. What happens between now and 05 is anybody's guess, but I have read that there is a real good chance 6 speed tranny and independent rear suspension is already being shelved. There are just too many variables being shuffled around for anyone to be certain at this point. However, the three valve head with a more efficient twin screw could very easily make up the HP/TQ gap if they choose to not go with the 32 valve setup....

i've been checking out the new 5.4 04's coming in for PDI at my shop, those heads are funny looking, but, you won't believe this, the engine bay is BIG really BIG, it will be easier to work on, and probably only take an hour to change spark plugs.
plus the regular 5.4 04's drive really nice and stiff on corners and turns, so just think about what the L will be able to do.

lots of stuff on the concepts never make it to production. why 3 valves though? why not 4, atleast its an even number. i wouldnt be suprised if we ended up with the same motor.

Interesting...for some reason i didn't realize it was a DOHC setup that was reaching that much power. I REALLY want it to be a 6 speed though guys. Thats the thing i really didn't like about the current lightnings. I love them except i think automatics are boring and less reliable
I would think cost wise they would use the 3 valve heads because you'll get about near the same power in the end with less moving parts and a considerably cheaper cost / head.
