Nat Gas be hard on engines
We sold the shit out of 8.1s and 5.7s in generator applications. Detonation, cooked manifolds, and head gaskets destroyed them.
What do you think they did to their "specifically designed" 6.0l? Beefier head gaskets and stuff?![]()
Man, I am not sure. They may be just fine these days. I am sure that the ones I am speaking of were just "converted". The same engines in a gas application did just fine.
