Running 65 it turns right about 2000 rpm. I have a 342 to go in my burb and I think it will be a good combo. That one is getting a 5.3 4L60 combo.

Thanks Jimmy. Right now with a TH350 and a 283 Im turning 4000-4500 rpm at 70-75mph. Waaay to high. I will see how the 3:73's do after I get everything in and set. Id like to take it on long runs but cant ubtil I get the rpm and mileage issues fixed
