Industrial engines are purposely de rated and detuned so they can be safely run at wot all the time. Has **** to do with torque production. I used to design applications with industrial engines. Example Ford 2.3's with 2500 rpm max engine speed. Wot all the time. 49 HP. Woohoo
So chrysler engineers didnt design a purpose built engine? Nonsense. Part of that design of the 413 RV engine is the cam with less than 200 @.050 duration. Another part is the small runners in the heads and small valve sizes.
To say it has nothing to do with torque production is asinine. It is absolutely about torque production in the rpm range the engine is designed to function in.
As far as your ferd example goes who gives a rip. Take it to a Ford message board and whine about it there.
