hello eveyone, is anybody using the blinker tach that was availble on the 67 chevelle? i'am going take out the autometer and plan on buying the gauge package from shift works and a reproduction tach from one of the chevelle suppliers. my buddy also has a 67 ss chevelle with the orginal tach ,he also has a aftermafket tach installed.he says the gm tach's r.p.m. response time is way slower than the other tach, we are both running msd 6-al's his aftermarket tach requires a tach adapter,mine does not. are the repro gm tach's any good. when i change out the tach/gauge package, i'am also going to a hei type ignition with msd compoments. thanks for any input and opinions. dave
