aluminum heads on a diesel is bad, imo. take the different expansion rates, combined with high combustion pressures is not a good time.
ah the old 2 stroke detroits. good times.
yes torque numbers between a v8 and I6 can be similar, but the I6 makes it at a more efficient lower RPM. also, most big v8 diesels had very poor longevity in a high load application. in tractors especially, most v8 diesels grenaded by 3000 service hours while most I6 engines would go 8000-10000.

We had an IHC 1568 (DV-550 V-8), now that thing was a beast and sounded like a race car in the field. Not sure on hours as I was younger and we had it for years, but when we got rid of it, we got a 1586 with the DT-436 and my Uncle STILL has that thing. My Dad said the V-8 was fine but loved the fuel. But you dont really see V-8's in tractor much anymore. Had to be a reason.
