No, the reason these "low power" M96 engines do not suffer from scoring is due to the fact that their cylinder walls are thick enough and cooling sufficient. The concept was not bad at all. The problems began with ever larger displacements and thinner cylinder walls in combination with inadequate cooling.
Please do not start a "scoring thread" ;-)
