NOS Cam and Crank Sprocket
 

NOS Cam Sprocket 12552128 and NOS Crank Sprocket 10128346. These parts are for a non-roller, hydraulic flat lifter cam. I had these parts to freshen up an old SBC I had until I decided to use a roller cam engine in my truck. These parts are the heavy duty truck parts that DO NOT have the nylon teeth. $80 shipped.
