I have to wonder if the M8 with 131 displacement and stage IV is going to stay cool enough with oil cooling and the twin cooling.The cost would be nearly equal (upgrade wise) to a Carpenter install. About $6k plus exhaust. Apples and oranges. Both cool, I’ve ran both, to some it’s not just which is faster. The M8 is an awesome power plant, as is our beloved triple.
