How do you guys decide at which RPM you should be shifting at? There's no real manual for it and without a dyno you don't really know where you make peak power. My cam is good from 4000-7500. I shift at 6800-7000 regularly and once in while 7200 but anything over that it sounds like a rod is going to come through the firewall. I have a forged rotating assembly so I know it can take the beating but am I gaining anything by shifting at a higher RPM? Heading to the track this weekend if it doesnt rain and hopefully my signature will change to 11.XX.
