Bud,
I think you better check your Tach. I get 25 MPH per 1000 RPM which
translates into 3000 RPM @ 75 MPH. These values are based on
book values of 20 MPH per 1000RPM in fourth direct, timing speed
off of the milage markers on the interstate and calculating a correction
value for my tach (which reads about 200 RPM low, BTW).
So 2800 RPM @ 70 is about right.
Maybe your engine is so finely balanced it just seams to be turning
slower. ;-)
