For highway it even a bit tall geared in my opinion. 2200 RPM's it is going 80 and it is pretty quiet. I agree about no radio. For this car I am thinking the other lower geared overdrive would be a much better choice. My motor doesn't seem to be very happy at 2000 RPM's. Seems to be lugging and just not in happy place. Shift to 4th and ****s ready to happen but thinking the racing OD is a way better choice for this car. Curious to hear from someone running those gears to hear the RPM's at 75 to 80. Thinking about 2500 to 2600 Rpm's which the motor would seem to like more better
