Lots of threads on Headers, but how about one more quick one!

I built a 69 big block Dart in the 80's. It had Hooker fenderwells, I think they were the only ones available.
Yeah, they limited front tire size.
One great thing though, was the easy access to everything underneath without those damned things in the way.
In general, I remember reading that fender wells were used because you could get a nice straight tube from each cylinder before they curved, which apparently helped power.
