thinking about swapping the 12 bolt 3:08 pegleg for a 3:55 posi unit.
i still like to drive 70mph = 3000 rpm now. so i guess if i went to the 3:55's i would run somewhere around 3450rpm @ 70 and about 3000 rpm @ 60 mph. see myself taking maybe 2 - 150-200 miles trips a year and the rest is around town. would this long trip be hard on the 396?
how about 3500 vs. 3000 rpm if i leave the 3:08's?
it has been balanced and has a 280h comp cam. not sure what the CR is, but the motor is a '69 396/350 hp and it has a Richmond T10 manual 4 speed.
