PS: Online speed/rpm calculators show that at 65 mph I'll be turning about 1500 rpm.

Just my opinion, but I say too high (unless you're setting up for the standing mile, in which case your theoretical speed at 6000 RPM will be 260 MPH).
**My granny thankfully drove Ramblers for the most part, but she thought the accelerator pedal -- and the brake pedal -- were on/off switches. (The phrase "stab it and steer" comes to mind.) True story: In a moment of brilliance, her son (my uncle) bought her an uber high mileage puke-green 4-bbl 350 '69 Nova when she was about 85 because it was cheap. Within a week she took out the windshield, the A, B and C pillars on the passenger side and the back window when she clipped the tailgate of a large truck. It was spectacular, and no one was hurt. I still remember her exclaiming "Ach du Lieber!" (OMG) as she described the event. Bless her heart and rest her soul.
