400hp or more in any of todays 1/2ton pickup is asking for reliabllity and longivity issues. These motors aren't even displacing 400cubes and we're asking for 1+hp per cubic in of displacement, and if you're wanting to get 300,000+ miles out of that motor while beating the piss out it (like what the raptor is going to see), you better be made of money to afford the $10,000+ engine and tranny upgrade.
i have an 08 and while yes its the lowest rated in terms of hp, i could care less as i can set the cruise at 75 while pulling 7,000lbs worth of race truck, trailer and tools, and that is pretty frickin good.
Having 411hp will make the raptor one heck of a truck (hell thats even more than the gen 2 lightnings), but only 434ftlbs of tq, that is disappointing, they should of aimed for V10 tq levels if they wanted a true powerhouse of a motor (or just used the V10

)
