OD off at 65 with 31" tires and 3.92 gears nets 2950 RPM.

I don't know why your numbers are different than mine since OD off on both the 44 and 46Rx
trannies should be 1:1, but those are the numbers I see on my truck.
YMMV,

John, are you talking OD on or off?
My 2K R/T with 3.92s and 28" tall runs 90 at 3000 in OD or 60 at 3000 with
OD off.
Hell my 99 R/T with 4.10s gets 85 mph at 3000.
