HOLD ON THERE , just for the record the GM 3.6 OHC engine is 219.65 cubic inches and makes 320 hp ,that is 1.46 hp per cubic inch. the LS3 OHV is 376 cubic inches and makes 426 hp so it makes 1.13 hp per cubic inch ,the Ford Coyote 5.0 makes 430 hp out of 302 cubic inches ,that is 1.42 hp per cubic inch. I could go on and on but as you can see GM itself knows the deal . Push rod engines are cheaper and easy to build . It's about the $$$$$$$$$$$. Torque at a specific rpm ,the Ferrari wins. It revs higher to make the power but doe's so none the less.

You still don't get it. The displacement of LS3 is big, yet it is more compact and consumes less than most of the engines you just listed. Europeans care about per-liter measure, since they only have DOHC engines and the displacement pretty much dictates the packaging and weight of the engine. This is not true for pushrod engines.
