Reply to comment by vferrero14 in ELI5: How exactly do we get some much power from engine now, than we did 40, 50, 60 years ago? by Micromashington

A lot of (mainly American) manufacturers maintain that pushrod can be superior due to lower centre of gravity. i.e. the main cam is deep inside the engine.

It's also simpler and weighs less, especially a V8 with double overhead setup. The four cylinder overhead cam isn't as bad cause you just have two instead of any V config will have 4 cam shafts. Weight can effect fuel economy and simple (pushrods) always has its own benefits.
