the red line is not 6k forsure......a dodge truck with a 5.7L shifts at 6300rpm

Actually most stock sbf redline at or around 6 grand with extra work to the motor and cam you can get more rpms. Being the motor is stock with a factory cam I say it would be best to shift around 5 grand or maybe a little higher but not much. There is no need to spin a mostly stock motor higher then that since you will be out of the power band.

i was guessing just to set it for 5300-5500rpm

I would say drive it a couple times and figure it out. Most of the times you can fill the power fall off when you hit your peak, I can in my car when I get alittle over 5200.
