Anyone ever turn an old Dart into an ultimate daily-driver?

In high school, I drove a '67 Grand Prix with a 400/Carter AFB 4-barrel. I disconnected the accelerator pump and choke and had the initial timing cranked up quite a bit. I also ran an underdash vacuum gauge and didn't let it drop below 10 inches when I accelerated, which also ensured it never pinged on the cheapo gas I was running. I think I was knocking down 20 MPG with my mostly-freeway driving. I also drove like I had egg shells under my right foot.

The only downside was that I had to pop the hood and give the disconnected accelerator pump plunger a few pumps to get it going in the mornings. It was like an experiment and it was kinda fun.
