Happy to offer any insight i can. They are not necessarily "high" rpm deals. Although to most Mopar guys I am sure the RPM is scary smile My old combo was shifted at 8800in the red car and he went 8.30's at 3600lbs with a liberty. I went 8.19 at almost 3400 in Vegas with it and a TH210 but it saw 10,000 rpm with me.
