Tried it and had trouble with oil temperature. water would run 190 and oil would go over 280 and keep going i guess, always shut if off and cooled it off. i would not do it again.
tried a large external oil cooler and then a radiator with a heat exchanger in it. neither stopped the problem, only slowed down the process some. the guy i sold it to ended up changing the block to fix the problem.

But that was our combination
