Last winter, I installed a gear vendors overdrive into my 1971 Ford Torino GT(351c, C4 auto trans, 3.5 rear gears). This video is about the driving experience of the car with the gear vendors unit. The gear vendors is a great solution if you've got a classic car that has a little too high of a gear ratio for cruising at freeway speeds. Midway thru filming the video, I installed a tach to show the difference in cruise rpm's with the overdrive on compared to the overdrive off.
