Coyote 5.0 Difference F150vMustang
What is the difference between these two seemingly identical engines? Truck has 360hp yet the stang boasts 420hp.
Cam difference? programming? Bueller?

From what I have read. The differences are in the cams, pistons ( higher compression on the Mustang) ECM programming, and the exhaust manafold. There might be some more, but that is all I know about. I do know we share the same block, heads, crank and intake manifold.

Different heads/cams/intake/tune. The short block is the same:
http://en.m.wikipedia.org/wiki/Ford_Modular_engine
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 (520 N·m).

Inebriated 4 ur safety
Yeah, what warsurfer said.

It is funny how many people still think that Ford just detuned the 5.0L to shine the light on other engines in the line up. They did it so that the 5.0L can reliably tow the weight it is rated for with more low end. Truck manufacturers learned a long time ago that you can't just slap a car engine in a truck expecting it to do what a truck needs to do reliably day in and day out. It's the same reason the 6.2L in the F-150 is more powerful than the 6.2L found in Superduty that is rated to tow more weight along with the heavier truck. There are even two different power ratings for the 6.2L in the Superduties depending on the GVWR.
Also, the 420hp for the Stang is on premium fuel. It is 402hp on 87 octane.
While this 5.0-liter V8 engine is similar to the one powering the 2011 Mustang GT, it has several important differences to optimize it for the harsh duty cycle truck customers demand. First, the camshafts were tuned to improve low-speed torque, which is key to truck customers. Also, the 10.5:1 compression ratio was optimized to reduce knock tendency at lower engine speeds while towing.
The hardware added to the 5.0 specifically for F-150 includes an additional oil cooler, which helps extend the life of the oil to 10,000-mile intervals; foam covers for the fuel injectors to reduce NVH; and cast exhaust manifolds for improved durability. The new aluminum block is 70 pounds lighter than the 5.4-liter V8, which aids fuel economy and improves handling. The engine’s forged-steel crankshaft also ensures durability.

I know one of the truck magazines did an extensive article comparing the 2, but I can't find it now. I'm sure the link is posted in another thread on here too.

The intake cams are unique to the truck. The TiVCT is tuned for more low end TQ which will rob some HP. Mustang has tubular headers and a slightly higher compression ratio. The Mustangs 412 is also on premium fuel. It is 402 on 87 only 42 higher than the F150 on 87.

At my buddies shop, they have several 5.0 engines, two Coyotes, a Roadrunner (Boss 302) and an F150 version that a customer brought in to have "built" for big boost to put into a SN95. What I have seen from the engines so far;
Intake manifold: Dimensionally identical to the car, same port shape, size and cc. Differences: no bosses cast for the engine cover the car has. functionally the same.
Heads: well documented that the intake cams are smaller, and exhaust is same. Now, the valves and the ports are the same size, not sure about the port cc, as they have not cc'ed them yet, but if they are different, it is by less than 10cc by looking at them as they appear exactly the same. I have read that there is a difference in the valve job, ie a wider exhaust seat for improved cooling of the valve under load (towing). Otherwise, they look identical (except the Roadrunner....that thing is nice!).
Shortblock: Pistons are different for the lower compression, but material type is same as ALL the engines, Hypereutectic. There is a rumor that the rods are differnt in the trucks, but I suspect that they are the same.
Tune: Pretty obvious here
Exhaust: Manifolds and a single exhaust vs short tubes and duals
As for hp ratings, everything appears to be underrated...... my truck ran 92 mph in the 1/4 with a race weight just over 6200 lbs, calculator suggests about 380 ish hp, which is in line with the 306 rwhp that I put down (assuming 20%). We all know Ecos run around 315 ish rwhp (around 390hp) and Mustangs routinely put down 350-360 ish rwhp through autos (440-450 hp) so they are obviously underrated too.
Like Al said, the differences are in the power curves, and the engines are detuned (including hard parts) to where Ford thinks that they will have the least amount of issues with warranty work from idiots trying to tear stuff up. Could a 450 hp Mustang 5.0 tow 15,000 lbs? Sure, but the guy doing the towing has to know what he is doing as the heat generated is going to be ridiculous, and the majority of folks will just put it in drive and feed it gas until it burns up.

The "bosses" are present on the F-150 5.0L intake manifold. Several here (including myself) as well as on other F-150 forums have installed the Mustang's engine cover.

As for the cover, I know it has been modified to put it on the truck (your looks great by the way!) and when we checked it, not all of the bosses were there, or maybe they were different heights, I forgot, it's been over a year since we looked at it......
