I saw all that, after the fact, and decided not to edit anyway.
But let's be clear: The bankruptcy of the manufacturers, as complicated an issue as it is, is a straw man. The market for "more content" is well served. And the topic is not the cars, the topic is the type of engine, and to bring bankruptcy to the table only serves to distract from the fact that the LS series engines, with all their outdated pushrods, produce more power in a package smaller and simpler and less costly to produce than any comparable-power OHC engine in production. All the European and Japanese manufacturers have wonderful OHC engines, simply fantastic, jeweled pieces, taking advantage of all that OHC has to offer form the standpoint of valvetrain stability, control of timing events, and cylinder design...but it costs them dearly in price, packaging, or both.
Bottom line is, there's no argument that OHC is the preferred method of making power, for many reasons...almost all of which are trumped, in the case of real-world V8's, by the addressing of very real packaging concerns and smart workarounds for the most important of their other disadvantages. It can be done, and it has been done.
Packaging not an issue? OHC, hands down. Cost not an issue? OHC, hands down. But in the practical world, those constraints are very real, and the pushrod engine has been shown to address them admirably, when executed properly.
