Got a 1990 Chev 4x4 truck with 350, 700r4 tranny and stock size tires. My question is what should my truck be revving at driving 60mph? I threw in a tach and it is revving at 2600 rpm @ 60. Some say that's too high, your tranny must be slipping. Not sure on what gears I'm running but I'm sure they are 3.47s or something like that.
