Welcome to the BROTHERHOOD OF THE BEAST!
Here is a chart you might use to see if your tach is tracking correctly...assuming your speedo is corrected for the 410 gear!
And...(IIRC) there is a way to determine the RPM from the DIC (digital information center - the display in the dash). As I seem to recall,
(someone please chime in here!) a number can be retrieved and a multiplier is used to ascertain the actual RPM. OR, if you have a scanner, of course you can read and compare the analog tach to the digital reading.
