3.08 to 3.73... what gains?
My 89 5 speed has 3.08's in it right now and I have a 3.73 Richmond kit in the garage that I have to find time to install... what kind of gains can I expect out of these lower gears?

3.73's are a bit to steap for your stock Lo3. You will be out of your power band to fast and may actually have minimal gains. 3.42 gears are about the best for most LO3 motors. Some have seen no real drop in ET but have picked up a mph or two. They are still a great mod once you add more power down the road.

What about an L98? Any gains going from 3:27 to a 3:73? How much of a hit on gas milage? And what are any other known cons? Thanks.
