The primary difference between the 302 and 302 HO (High Output) engine lies in their performance specifications. The standard 302 engine typically produces around 205-220 horsepower, while the 302 HO engine is tuned for higher performance, generating approximately 230-300 horsepower, depending on the model year and application. The HO variant often features upgraded components such as a more aggressive camshaft, improved intake and exhaust systems, and sometimes higher compression ratios, enhancing overall power and torque. These enhancements make the 302 HO better suited for performance-oriented vehicles.
Isit because of the valve opening distance and the makeup of the cam shaft?
The difference is in the injectors and engine computer. You can not tell by looking at the engine.

no
One way is the firing order. The 302 HO has the same firing order as the 351. So, if the firing order is 1-3-7-2-6-5-4-8 you have an HO engine. If the stock manifold is on the engine, it will say "5.0 Ford HO". The exhaust manifolds were factory tubular headers. They had roller cams.
Yes, if it's a 302 and not a 4.6 like in the newer mustangs the 302 and all aftermarket 302 heads should fit.
The HO engine had higher compression, bigger intake valves, and a different cam. Also, it was painted black.
There is an alternate firing order for a 302 HO engine. Standard Ford 302 firing order is 1-5-4-2-6-3-7-8, HO versionis 1-3-7-2-6-5-4-8
The difference is a 5.0 EFI engine is making 225hp stock a 5.0 HO is making 275-280hp
The Ford 302 H.O. firing order is the same as a Ford 351 engine. It is 1-3-7-2-6-5-4-8. It is totally different from a standard Ford 302.
Two. The standard Ford 302 and the 302 HO VIN M.
Very simply...it turns it into a 302 HO. It also changes the timing of the 302 to the timing of the 351.
