Actually, they ran more like 16 flat stock from the factory as an Automatic. The 5 speeds were a little quicker... mid to low 15's.

On my peanut cammed 305 auto, with a few bolt-on basic mods: AFPR, headers, a little chip tuning and an MSD I was running 15.3s @ 1250ft which is about 15.1 at sea level.
