MSD Start Retard Timing Control

[68camotion]

This start retard control is used but works fine. It will work with any MSD ignition and 8, 6 or 4 cylinder engines. It does not come with the 2, 3, or 4 degree modules, (which are not required for it to function properly) or mounting hardware, but has all wiring and is setup to retard timing either 10 or 25 degrees during cranking or when engine reaches 1300 RPM's. The modules that go to 4 degrees are only ever needed if one wants to retard timing from 4000 RPM's and up. If you want to buy the set of modules for this purpose they are part number 8777, here is the link on Summit http://www.summitracing.com/parts/msd-8777/overview/ . Brand new these go for about 275.00, I am asking 150.00 shipped
