I've been running a factory (not repo) tach with an HEI since 1987, I've put approx. 175000 miles on it, and haven't had a problem. I also had one other truck for about a year that I had a factory tach with an HEI and that one worked good also. I come on this site to learn about these trucks and find it interesting that some of the new tachs burn up with the HEI. If I ever have to buy a new one, I'll be researching more about what to do. I think I saw where somebody mentioned a filter?
