And that is what would happen to the Toy motor in real life, Not the fake *** comertials the play up on TV.
You guys that seem to be embarassed by your 5.4 should get a V-10 SD. 450 ft lbs to haul your loads.
If your not hauling or towing and just want a fast truck for a grocery getter than for gods sake go get a Super Charger. For $4000 you can have a very fast F150

FYI, I own a Super Duty with V10/4.30's and an '07 Tundra 5.7.....the Toy will out pull the Ford any grade, anytime with the same loads.
The fact a motor has high peak HP/torque does not mean it doesn't have a broad, long curve that starts low. (The Toyota motor)
Modern technology (VVT, 4 valve DOHC heads) can be a wonderful thing; and I have no doubt in my mind that Ford has the know how and parts to do it.
Of course, GM does it with higher displacent (and VVT in the case of their 6.2 screamer) and seems to get good results.

Also, those motors are in cars - not trucks - so you'd be giving up some of that HP to shift the torque curve a little lower... US had something close in the 2000 R

Again, Toyota and Nissan make DOHC 4 valve truck motors that say otherwise.

VVT is good, but not god either, can't make mountains out of mole hills. now, an FR500 style intake... that'd be something worthwhile

The 5.7 makes more horsepower than both the 2V and 3V V10 and slightly less torque than the 2V 6.8. (and sadly, the Toy 5.7 puts more power to the wheels than either version of the V10)
Wonder why some think the Toy 5.7 is "peakier".......the thing makes a LOT of torque down low.
Maybe the fact it has such high "peak" numbers confuse people.

Ok then......380HP with less agressive cams.
That number sounds familiar.....with 400#'s of torque, it would equal the Tundra.

Well the 3V makes 462 ft lbs at a low 3250ish if memory serves correctly. The 5.7 toyota makes around 400 at at a comparable speed. Thats pretty significant. It does have a good bit of torque down low but it doesn't compare to the 6.8.
The toyota motor makes great numbers i won't dispute that. I don't think it is in any way in the same class as the 6.8, one of the true heavy duty gassers left.

there are several RV forums on the net that constantly sing the praises of the 6.8. Many choosing to compare the truck to the diesel. These guys regularly tow very near or even over the capacity of the truck. 6k lbs is not a challenge for any 1/2 truck. It is under the rangers capacity. 2 jet skis are probably below the rating of the escape...

This was never meant to be a Toy vs Ford discussion.....somehow, they always end up being that way.
My one and only point is I'm glad Ford is stepping up with a 6.2 to compete....but I've also always felt they had the parts bin to step up any time they wished to.
As a former Lightning owner, I think Ford could have even FACTORY appeased us with a blower....(then we'd get all the goof ***** crying how Ford has to cheat to compete)
