Review on MSD 8910 Factory Ignition Tachometer by Robert Rasmussen

Revainrating 5 out of 5

does what it says on the box

This MSD Tach Adapter did what needed to be done and should have made the original '68 Tic-Toc Tach charger work in conjunction with an MSD Digital 6 ignition unit (and Blaster II coil) and Edelbrock Pro-Flo 4 injection system set to 440, the tachometer does not work properly when the #8910 tach adapter is installed and the diode (which comes with the adapter) in the circuit is ok, everything is ok now .
