Another 440 Source exclusive big block Mopar part! These awesome fully CNC machined adjustable timing pointers bolt on to the front of the engine, just like a regular pointer would. They're fully adjustable, allowing you to set TDC exactly where it should be with the damper, etc you are using. These work with factory (7.25") diameter dampers. A super cool part that nobody else is going to have, but everyone's gonna ask where you got it!
