Life in the fast lane

I know your pain as I have 3.91s in my Dart. My rear tires are 27" tall and I turn 3700+ running 65mph+ down the highway. Getting an OD trans into the car will give you the best of both worlds with less of a performance hit compared to swapping cams and gears. With a "flip of the switch" I go from 3700 RPM down to 2700 RPM and I am running a non lockup converter. I am actually running the same Edge Racing 9.5" converter(3500 stall) I ran in front of my 904. Getting an A500 to fit is harder then swapping a cam and changing out a center section, but the results are worth it.
