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.

I think your statement about push rods vs overhead cams, while mostly accurate isn't completely true. Push rod engines were still used by a lot of American manufacturers throughout the 1990s and I'm pretty sure Ford still has engines using push rods. I do believe Ford was able to get variable valve lift with their modern pushrod engine but I'm not totally sure on that.
