Jeep has 4.0 and 4.0 H.O. What are the mechanical differences. Horse power?
I guess i could google horse power…
Sounds like a plan to me.

What makes an H.O. an H.O. is it that blower sticking out of the hood
A slight redesign in 1991 led to an increase in horsepower.
A “blower” sticking out of the hood?
“Blower” usually refers to a supercharger, and I have never seen a factory-stock Jeep equipped with a supercharger.
Perhaps you are talking about a hood scoop, but a hood scoop is not necessarily an indication of anything other than a styling affectation. Cars with a turbocharger or a supercharger will usually have a hood scoop, but I could probably come up with a fairly extensive list of vehicles without a forced induction system that also have a hood scoop–such as some Jeeps.
I was just screwing around…to much time on my hands
I understand that but whats different about the high output That is whats mechanically different
The H.O. engine had–IIRC–larger valves, larger intake passages, and improved injectors.
Possibly, it also had a higher-compression cylinder head.
That helps…Thanks
