Default How do you modify / correct the tach ?

I am considering several modifications to my 93 six speed Ruby, including replacing the cam and valve train.
#1. How do I modify my dash tach to read up to 6500 - 7000 RPM ?
#2. I just read a thread discussing the accuracy, or lack of accuracy, of the tach. How do I check for accuracy and correct the tach?
Thanks for the help?

Thanks for the tip, but I couldn't find anything usefull in any of those web sites. The older tachometers were available rebuilt, but not a late model C 4. I even went into Google search. Do you know the RPM range for an LT 4 ? That would probably work.
