I figured this is a good subject. What is the difference in these three Gen 1 long blocks and will all three run on standard Gen 1 Coyote software? Some threads say both the Intake and Exhaust cams are the same between these three long blocks and others say only the Exhaust cam is different for each one and only by lift. That is 10mm vis 11mm vis 12 mm. So what is every ones thoughts?

The Intake cams are different between the truck motor and the mustang GT motor
The exhaust cams are the same in the truck motor and the mustang GT motor
The Exhaust cams are different between the mustang GT/truck motor and the Boss motor

The ECU can be tuned for any combination of these cams.

Then all Gen 2 trucks have a different firing order. Is there a Gen 3 truck?

The 2018+ is the Gen 3 truck motor, rated at 395hp@5750/400 ft-lbs @4500

It has direct injection/port injection, spray bore lined cylinders, 12.0:1 compression-just like the mustang. Camshafts are different between the F150 and Mustang version, but I can't find anything verifying the firing order of the 2018+ truck motor.

Did the Gen 3 engines get revised heads again or are they the same as the Gen2 heads?

I believe I read that the cam phasers were changed on the Gen2 engines as well. Or maybe it was on the Gen3 engines.

Gen 2 went to the mid lock cam phasers, so you could retard or advance the cams rather than the Gen 1 and 3v retard only phasers. Cams and valve springs were upgraded as well for Gen 3. Exhaust cam phazers are new as well, stolen from Ford Racing's website:
On the intake side, variable camshaft timing mid-lock phasers carry over from Gen 2. The Exhaust phasers migrate to an in-cylinder head oil control valve for better control at all speeds and loads

I was looking at a video of a totally stock Gen3/A10 swapped foxbody coupe yesterday and it put 463 hp and 419 lb-ft to the tires. wow

I am sure that is at the crank.

That would be more then the BMW Law of 100hp per liter at the crank or no drive line loss what so ever.

Or....

It makes more power than Ford "says" it makes. Stone stock, full emissions controls cars are making 420 hp at the wheels with a OEM rating of 460 hp since 2018. So an unchained (so to speak) output like this is on par with reality.

It fairly accepted that the 5.0 DOHC is underrated.

So what do you know about the BMW horsepower law of a combustion engine? It's been around since the Red Baron. Two goals of a standard engine. 1HP per lbs and 100HP per Liter. So if this is so, then it's less then 10% driveline drag. Very impressive indeed.

Enlighten me. I've never heard of it in my 47 years.

1hp/lb and 100hp/liter doesn't mean much when 999cc motorcycles are making 175hp to the wheel and the engine well under 175 lbs. They're approaching 200hp/liter in mass production trim.

Speaking of engines, it can't be good for heat control to have all of that plastic shrouding on new cars today. I mean damn, you pop the hood on any new car and all you see is plastic covers everywhere. Here's the xtreme version below. Damn Lexus, chill out a bit!

I don’t think it really matters because even if the engine cover wasn’t there the hood would be.

It is possible to be a 5.2 cross plane.

I don't have any first hand information regarding this vehicle, but I'll speculate that there are at least two factors going on here. First even though the engine might well be stock, ie. no non production parts, I'll bet the tune isn't the factory production tune. The factory tune is very safe and conservative even alloying for the use of 87 octane fuel. No manufacturer wants to have to make good on warranty claims. A more aggressive and somewhat less forgiving tune could certainly bump up the power. Second I doubt that the dyno correction factor is the same one used by the auto manufacturers, often referred to as SAE. The hot rod industry generally uses a factor that is a bit more generous. Between these two I can see where an engine rated at 460 hp at the crank by the factory just might squeeze out 463 at the wheels. The type of dyno used also matters.

Are people actually in disbelief of this fox body?
Plenty of 2018+ mustang GT's with longtubes and free-flow exhaust making 450+ at the wheels. Even F150 versions with just an E85 tune making over 400 at the wheels.
