I am not sure if those numbers are right, I have calculated 3500 RPM for a '59
Minx with a 4.55:1 rear with 5.60x15 tires. Even with smaller wheels, I would
assume an Alpine with a 4.22:1 rear would have to do better, and a 3.89:1 rear

My speedo is completely accurate, as it was just calibrated, but my tach is
probably off. I do recall others reporting certain RPMS, etc. I do
believe though that before I changed to the OD (and the speedo was not way
off), my tach would read about 4000-4100 at 65. Now, with the OD and the
calibrated speedo, at 65 I'm reading about 3600. I believe others have
reported 3300 rpm at 65. For a long time, I've believed my tach to be
about 250-300 high. So, this makes sense.
That all said, I think someone had and equation for all this, and thus had
the exact numbers, perhaps taking into account some tire size change too.
