that amazes me you're only turning 2300 rpms with 4.56 gears at 65 mph..is the speedo right? did you get it calibrated when you did the gear swap cuz it does throw it off...not sure if you know I'm just sayin. because 2300 rpms at 65 mph with 4.56s in an auto truck seems a lil unbelievable
@midnight347 I do have 4.56 gears. It is a 4 speed auto, 4th is 0.70 and the tq converter locks out with very little slip. The speedo is correct and was done via a dyno.
