rear end question

Thanks,
can you explain the ratio thing to me I get alittle confused on on the ratio. What would be a good ratio to run, higher ratio means _____ and a lower ratio means _______

Well a steeper gear set for example drag racing would be like a 4.56 and a highway set would be like a 3.23. If you pull the 3rd member it will tell you the ratio on the outside edge of the ring gear.
