What ratio is recommended for a 1955 Chevy car with a 6 cylinder engine and power glide transmission for highway driving (cruising at 65 MPH). My car now has a 3.55 and it seems to low.

For many folks your ratio is the sweet spot. I live in an area where 65mph will get you being passed by cars on both sides. My 57 6 cyl really sounds like it is wound up at 70-75 so I stay in the slow lanes at 70-75. If I was going to keep it with the 6 I would go with a 3:08 and a 350 trans. Better in town and better on freeway.
