Well,
I finally got around to digging out the instrument cluster and checking out how the tach works without using a filter as suggested by American Autowire. All I got to say is that nothing beats the experience that is on this board. YOU GUYS ROCK. Thanks to all who posted. As you can see by my two pictures, the 1970 tach read 750 RMP at idle. When I compared this to my 2006 tach, which read 700 RMP, I can say that it's pretty much dead on.
Thanks again.
