Back when it started w/ the mustangs, they put a 351Windsor cam in it. It just changed the firing order. Then they started putting forged pistons & roller cams in them. '92 & up 5.0 trucks have roller cams. Speed density trucks have the old 302 firing order & mass air trucks have the Windsor firing order. But they're not exactly "H.O."

The term "HO" has been used on various models and included different components throughout the years. On the F-Series/Broncos in the 1980s it referred to the 351/4 barrel (or "V") vis a vis the 351/2 barrel.

There really is only one 5.0HO and it was only ever put in cars, the cam, intake, pistons, and computer are unique to this motor. The vast majority of all late model('87+) 5.0 motors share the same block, heads, and rotating assembly(with the exception of pistons), but.. in terms of peak output the truck motors actually have more potential because it has the largest volume intake by far. The '87 to '92 HO motors got forged pistons and that is beneficial if power adders are used, but natuarally aspirated make no difference.
The Explorer/Mountaineer motor actually has more HP potential than either the Mustang or truck motor due to the GT40 heads, but it was never considered a HO.. probably because of the RV style cam that was installed.
Bottom line is you're not getting anywhere near full potential form any 5.0 with the stock camshaft, there's lots more power waiting to get out.

Ok. In '94 the 5.0 engine in the truck & the Mustang are essentially the same. They have different intake & exhaust manifolds & possibly a different cam grind (couldn't find much about specs). Of course the totally different ECM controlled fuel & ignition timing curves. According to Ford, though, the Mustang "H.O." engine only produces a few more horsepower than the truck engine. Phenominal.

A)most TQ
b)most peak HP
C)widest powerband
Most TQ will have E7 heads, F4TE cam + 1.7 rockers, and a HO intake with a ported lower.
Most peak power will use the GT40 heads, HO cam and 1.7 rockers, and the truck intake.
Widest powerband is the same as above with the GT40/Explorer intake.
Use a mustang mass air system with all for optimum results

Zero all by itself because the truck intake is not restrictive.
