CID = cubic inch displacement HO = high output

In the 80s the F150s and Broncos came with at least 3 engines a strait six 300ci or one of 2 V8s a 302ci(5.0l) or a 351ci(5.4l).
Every ho scale train I have had worked on any ho scale track.
It should be a 5.0L V8 302ci motor.
HO 1966/67 1500cc
The difference is a 5.0 EFI engine is making 225hp stock a 5.0 HO is making 275-280hp
At least 200,000 miles.
Isit because of the valve opening distance and the makeup of the cam shaft?
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.
29 hp taken from Polaris website. They have there 400 ho Ranger listed as 29hp and it has the same 455cc carb engine as the Sportsman 400 ho
The primary way to distinguish a 305 from a 305 HO (High Output) engine is by checking the engine code and specifications. The 305 HO typically features higher compression, different camshaft profiles, and upgraded components that enhance performance. Additionally, the HO version often has a distinctive intake manifold and may be equipped with a more aggressive exhaust system. Checking for these characteristics, along with any factory documentation, can help confirm the engine type.
