i ran 4:11s with my 80e and it was great, even for a DD, remember the 80 e and 60e have the same overdrive gear ratio so nothing will change on the highway, also i liked the 80 much better because 1st shifted out at 49 2nd shifted at 91 and 3rd shifted at 152, never found out how high OD would go this AWD trans will be getting an 80 when it gives up the ghost.
