Big Blue, with 3.54’s and no OD, is spinning that 460 at about 2500 ROM @ 65 MPH. Way to fast for my tastes. Should drop to 1900 with the ZF5.
Will the 460 pull that? I should think so. Dad’s warmed up 351M pulled the same gears perfectly on the highway with a LOAD of furniture in the bed. Motored up the big climb on I-40 between Nashville and Knoxville on cruise - with the same ZF. 😉
