Re: Tachometer Filter For HEI ?
May need more info to assist you:
1.What kind of HEI?
2.Stock tach gauge or aftermarket repro?
My understanding is that a filter is not needed. The best way to test is to first ensure you have a good working tachometer, you can mock this up in the engine bay first for testing. Green wire goes to the "tach" hookup on HEI. Keep us posted.
