Even a 4.22:1 rear wouldn't give that RPM- the 3500RPM I quoted was with a
4.55: 1 rear! (with 15 inch rims)

If your car was factory equipped with an OD it would be stamped into the data
tag. It is very possible that your have an OD rear end though. There
was a batch of non OD Series V's sent to North America with 4.22:1 rear ends. I
have been replacing those 4.22's with 3.89's in the Series V's that I
have encountered and it makes a huge difference. It's more than likely that
your tach is correct and you just need to swap rear ends. The black
Series V we just restored for Brian Shilt had the same problem. His car was
undrivable on the highway. He is now very pleased with how it runs.
