I have a 3:73 rear gear with a 0.68 fifth gear and 15" tires. In fifth at 100 MPH its at 3000 RPM. I do not use fifth unless I'm on highway and all the traffic is doing at least 70 MPH. Its great for gas mileage on the highway, but I'd rather have a 0.82 OD gear.

Here is a great calculator for SPF's
