I have a 3.31 rear with a toploader (1:1 top gear), and find cruising above 70-75 (2900 to 3100 RPM) starts to get weary, and earplugs are useful, almost necessary, due to wind as much as engine/exhaust noise...the motor is doing just fine, but I'm not! Below 70, (particularly at 65 mph, 2700 RPM) it cruises fine, and engine noise is not a problem.
