Might as well weigh in here, Get a friend (unless you own one) with a
portable GPS receiver and measure your speed with that.  It's about 2
digits more accurate than the speedometer, and you can do it at any speed
you want (nice to check the linearity of the Speedo)

Dave,

Using the owner's manual data of 482 RPM @ 10 MPH (Carb/USA Market TR6)
and
multiplying that times 6.5, we get an RPM @ 65 MPH of 3133.  However,
before
I would start tearing into the rearend.  I would consider two other
possibilities: 1.Is the speedo reading correctly?  2. Is the Tach reading
correctly?.  Checking the speedo is easy, just get a friend with a modern
car, and have then drive next to you @ 65 (on the freeway).  Is your
speedo
also indicates 65, then your speedo is OK.

Hope this helps,

Hugh Barber

Ok, its a nice day out.  So I took her for a ride.  Remember: my 1969 TR6
4-speed manual transmission, first time on the road in 17 years?  Today I
drove several times at an indicated 65 MPH on the speedometer and the
tachometer indicated 3650 RPM !!!!!!  Help.  Too high.  What does this
mean???  Do I have a 4.10 rear?  Did the previous owner change it maybe?
Could it have been ordered this way?  Or should I just disconnect both the
speedometer and tachometer and drive it without either of them, that way
I'll never know better (that's what I did 18 years ago, when I was last
driving it).

Sincerely,
Dave Herbert
1969 TR6 and nothing else
