I have an STR-12 in my '68 FB, #1405 & 1406 Edelbrocks. Choke works fine (when I remember it's there). Start car, idles at about 900 RPM, let it warm up good though, kind of twitchy with an AT when they are cold, but once it's ready, it runs fine. Mine is just a street car, don't plan on racing it.
