hey guys planning on going through my diff. i was looking at a set of 3.55 gears.....the car is set up for cruising (no track stuff) 3 speed auto and small block and 26 inch tire.....just wondering if i will be happy with these gears or should i step down to a 3.23....i will plan on hitting the expressway from time to time...worry about what kind of RPM's she'll turn...i still want to have fun with it...thanks guys
