IMO, the JH cooling as originally designed-two row radiator, no fan shroud-was totally inadequate for stop and go city driving in 100 degree F heat common during summer in much of the southwest US. I would guess the oil cooler was helpful in preventing some serious engine wear due to overheating.

The oil is heated not only by friction but also the combustion that takes place in each cylinder. Removing the oil cooler won't due much for performance (it doesn't weigh much) but may cause increased engine wear. Removing it is not worth the risk IMO.
