Repro Tach and HEI

[byates2]

I upgraded my 67 C10 to an MSD Streetfire Ignition. After this I bought an Instrument Cluster with a reproduction 8k tach from Classic Parts of America. At the time they stated that their Tachs will work with HEI as long as there is a Tach filter in line. Well i finally got around to installing it all these years later and my Tach went up in smoke (literally). Come to find out, they changed their stance and said their Tachs will not work with HEI.

So I've been looking around at different Sites like LMC and Brothers. Brothers responded to me and said their repro tach will work. Does anyone run a similar setup to me and have a Brothers Repro Tach working with their HEI? Do you have the Tach filter? Anyone have one from LMC?

Thanks in Advance!
