Before you knock those Chevy engines you might consider that an LS7 is on par in terms of weight and size with our S65 and produces nearly 100 more hp while simultaneously delivering much better mileage. Power per liter only matters if there are artificial bureaucratic restraints (per liter taxes) at work and the metric is actually meaningless as compared to power versus efficiency where those Chevy engines dominate.
A whole lot of people make the mistake of thinking that these engines are archaic but nothing could be further from the truth. They are some of the most technologically developed engines currently being sold and in every respect cutting edge.
