Never used, in original packaging Mopar Performance hydraulic flat tappet cam and lifter set for LA 318 340 360. .474” 280 duration. I bought this from another forum member and have decided to go a different direction for my low – compression smog motor. $250 plus shipping. Will trade for a good dual plane aluminum intake manifold for 360. Willing to add cash on top for Edelbrock RPM or RPM – air gap.
