Default What does High Output mean?

Well I was just wondering if what high output means, I have a 1997 Jeep Cherokee sport and wanted to know if I was equipped with a high output motor and tranny.

My jeep is a little loud by itself and is very quick if that means anything..

HO is the change from Renix to OBDII injection, this alone netted some extra HP from the 4.0 mill.
They also changed the head for better flow and this picked up a few more.
AFAIK all the 4.0's after Renix injection was retired became HO.

They are not labeled as HO.

The injection like stated above was improved with the H.O., and also the throttle body is improved I believe. (Anyone verify this?)

Any Jeep with a 4.0 inline six built after 1991 has the high output engine.

Silly question. It means that the crankshaft is about twelve inches higher off the ground than it is in most other vehicles - which we Jeep owners consider to be lower output, relatively speaking.
