Both the Melling CCS-1 and the Elgin E-293S are solid lifter cams. The Elgin cam is a virtual clone of the original equipment Corvette/261 cam, with the only difference being a slight change in the lash specification. The Melling cam has a few more degrees of "valve open" duration on the exhaust lobe. Neither one will have an objectionable idle lope, or reduce manifold vacuum or low end torque.
