3.90 YES or NO?

I got 3.90's also and like them but traffic in places go 80 mph now on freeways. Its the only place were 3.15-3.21 gears are better since 10 mph over 80 is 90 mph. You get places quick if you can do it for an hour.

For most people 3.90's are a great all around gear. Car Craft in 1970 said 4.10 gears and I think it was 27 inch tires were the best all around gear....this is how that BS 55 mph came about, it saved lots of gas--only to be used up by SUV's later on.
