SOLD Used MSD Pro Mag Timing Retard Box

As most of us know timing is critical to making blown motors run at there peak power the problem being there are some tracks that can't handle max power at certain points and this allows the racer to remove some ignition timing at strategic spots to help get the car from point A to point B. The box includes four vibration mounts but not a shielded wiring harness or timing chips. Box is perfect for a spare if you already have your engine set up with an 8168 box. Box is in great condition and looks like new. 8168 BOX HAS BEEN TESTED BY FUEL INJECTION ENT. AND IS IN GOOD WORKING ORDER.
