The Jeep 4.0L was an over-square inline six along with even larger displacement inline six prop plane engines, but that is neither here nor there since it is the bore/stroke ratio that determines when an engine reaches peak torque and max engine speed, not cylinder configuration. I don't see why this is so hard to understand.
When did the Jeep 4.0 become a high performance engine?
