Re: Tach Problems
If it is not too faded, there should be a stamp on back of the tach head for 6 cyl or 8 cyl. There is also a small hole that has an adjuster in it. I have heard of people tuning them that way, but i have never done it. Keep in mind, these were never real accurate from day 1. It shouldn't be off by 1000 rpms though. Good luck.
