F250 6.7 vs F150(Possibly EcoBoost or not) vs Nissan Titan

Hmmm...ever stoplight dragged a Ford GT(40), or more realistically a Lightning? Yes, in normal configuration I agree that the 5.4 was underpowered...I have one in my Ford truck. However, HP and torque do not tell the whole story either. The 5.0 is NOT a truck motor, its block and heads are car based 30 year old technology. I've ownned both, and can tell you that when all things are equal...ie ring and pinion ratios, options configurations, etc. the 5.0 is consistently operating at higher rpm's (rpm = wear) and searching for more downshifts than the bigger mill. All of that aside, gas makes more sense for the average tower than does the oil burner. I have no doubt that the 5.0 is now a better engine than it was, but there is a reason they use them in F150's and not the 3/4 ton. As unfortunate as it is the 6.2 is about as efficient as the failed V10 was factoring ho and torque numbers. All of this is moot of course, because new, you can only get what they are currently producing.

I think you may be talking about the 4.9 (302) which Ford marketed as a 5.0 when you're talking about "car based 30 year old technology".

The only resemblance the new engine (Coyote 5.0) bears to a 302 is that it's got 8 cylinders and is mostly made of metal and it's sold by Ford.

The 5.0 L (4951 cc, 302 cid) [12] "Coyote" V8 is the latest evolution of the Modular engine. Ford engineers needed to design a V8, specifically for the Mustang GT, that would compete with the GM 6.2L LS3 used in the new Chevrolet Camaro, and the new Chrysler 6.4L Hemi ESF in the Charger and Challenger. This engine had to remain close to the same physical size of the outgoing 4.6, and share other specifications with it such as bore spacing, deck height, bell housing bolt pattern, etc. in order for the engine to utilize existing Modular production line tooling. The result was the 5.0 Coyote, which produced roughly the same amount of power as its competitors, but with a much smaller displacement. To strengthen the block enough to handle increased output, webbing was extensively used as reinforcement in the casting, rather than increasing the thickness of the walls....more?

I'm a huge Ford fan, but all they did was strengthen the block and rework the heads on their car engine.

5.0 "Coyote" F-150 Variant

A torque-biased variant of the Coyote is produced as an alternative to the EcoBoost V6 in the new F-150 pickup truck. The F150 5.0L receives a lower compression ratio (10.5:1), intake camshafts with less duration, cast iron exhaust manifolds, and revised cylinder heads and intake manifold intended to promote low-end and mid-range power and torque. The engine retains the Coyote's forged steel crank and piston-cooling jets but benefits from the addition of an external engine oil cooler similar to the Boss 302's. The changes result in the engine's peak horsepower dropping to 360 hp (268 kW; 365 PS) while torque remains the same as the Boss 302 at 380 lb·ft

So tell me how a 5.4l is superior to that? Webbing is a better choice than mass for increasing block strength, IMHO. I wish my '07 5.4 made 380 lb-ft of torque. Or 360 hp for that matter.

First you were talking about 30-year-old engine technology (which made me think you were talking about the old 302) then you're dismissing the Coyote for being developed from the 4.6l, which was introduced in the early 90s.

Don't get me wrong, I wish my 5.4 had it too...its a pig. But the fact is that it has been ABUSED over the past 130,000 miles and has never once failed to perform It goes like a banshee over the hill to Tahoe, pulls my 28 ft overloaded wakeboarding boat thru the mountains and the twisties without a hiccup, and like my high school girlfriend...she might not be a 10, but shes dependable and affordable. Not so sure the 5.0 will ever be so trouble free over the long haul or if ignored and abused like this 5.4.
