Hey all, awesome ideas and good work so far! After coming up with nothing for this since the idea was first mentioned I suddenly remembered that I had the original "sleeper" on my shelf waiting to be built:
The "Little Old Lady from Pasadena" had herself a brand-new shiny red Super Stock Dodge. It didn't seem right to just build it box stock and leave off the scoop and decals, though, so I'm going through some old reference guides and plan to give it a little more period-correct oomph under the hood. Supposedly the '64 Charger concept car put out 600hp, so that's going to be my first stop.
