Those of you with 4.10s. What kind of RPM's you runnin at about 70 mph? I have a set in my garage, Im debating on weather or not to install them or not. I don't go on the highway a whole lot, the farthest trip I usually make is about 2 hours.
Yup right around 2500 if you have an AODE like me. I checked on a Fbody forum and its RPM calculator was dead on with my setup now so I assume it will be with the 4.10's.
2500 RPM isn't bad at all. Especially since I'm doing 2k now. Gotta love overdrive.
