I suggest being equally concerned with things like tires, tubes, wheels, suspension, steering and brakes. But if your car has one of the numerically higher rear axle ratios like 4.69 or 4.41, that plus the long 5" stroke of the engine leads me to suggest that a steady sustained speed more in the range of 55 would be more adviseable if prolonged engine life is a priority.

My 1934 Eight has the 4.69 rear, no overdrive, and also a 5" stroke, comfortable sustained speed is about 50 - 55. Of course I've got poured bearings and you got inserts, slight advantage to you in that department.
