This lists the chart on gears. How much power and how much weight. What RPM do you plan on finishing at?
The reason I ask is that your shift rpm doesn't seem to match your gear selection. Not saying you are wrong. Just need more info. If youhave the power and torque to run a lot of mph, then maybe you need a 2.90 something first gear. If not and you can't handle the rpm on the other end, maybe reconsider the shift rpm also?
