72 Dodge Dart Swinger

I believe I have the 2.7X or 2.9X rear end.

Out of curiosity what are your speeds and RPM ranges? I'm going to do some more adjusting on my carb for idle and air mixture, and check timing, but I feel my RPMs are high. I need to drive it more to get a better base line, but am curious what you guys get with similar factors.
