A point of clarification, please. I consider the deep wall block construction to be an asset. This places the crankshaft mounting up into the block for a stronger support and less flexing. The result being reduced vibration and prolonged life, which is of vast importance now some 40 years down the Road of Life.
If the Deity had applied a deep wall construction to we humans, our life expectancy would be doubled.
