It's refreshing to look at things in another direction. As fuel prices rise, mileage become more of a issue. How many threads start here with a "cam for my 318" question and end up talking about 400+horse builds. Not everybody wants or needs maximum performance. Those big cube hot rods often times get overbuilt and although they are fun to drive, you don't usually drive them 4 hours to a out of state car show. Also, there is a limit to how much horsepower you can hook up on the street. It can be a waste.
