I’ll throw in my own and question leaving off the Jeep 258 c.i. 6-cylinder and the Toyota 22R 4-cylinder, simply for utility and durability.

I agree with the Jeep six and add the jeep four used in the military jeeps for the same reason. I would also include the two stroke Detroits as well

While it may not have the track record of those engines on this list, I’m thus far pretty enamored with the 3.6 liter Chrysler Pentastar in my 2014 Rubicon.
