the new navigator that will be about soon has the same engine put into out f-150s (5.4L) then there is a option for it that puts out 350 horsepower. why doesnt ford do this and what gets those extra 50 ponies out??

 

I believe it's a 4v (dohc). What would a 4v swap consist of, (i.e. heads, etc) ?

 

Isnt the 4v 5.4 all aluminum?

 

i think that engine would well put us over the titan

 

Where did you see the info, on build and price?

It doesn't say what size the motor would be. And it is listed as a future option not into production yet. Ford had the same build/price setup on the 07 expedition with future options and it had a turbo diesel option listed.

 

And it's a $2500.00 option for the upgraded V8.

 

yeah i saw that too, could it be a entirely new engine? not just some add on's?
