I agree that is a bit cloudy. If cetane and timing were
that much of an issue, we should see them both do the same thing.
The .97 is essentially a bored and stroked .96. Same gasket could have sealing issues with a larger bore. Longer strokes will put more lateral load on the rod, especially @ higher RPM. I know the differences are not big but they still need to be factored in.
