I have two cams available. These are brand new cams reground in 1987 by Cal Cams in San Rafael, CA. Fit all the M30 motors with distributors. Both have the same duration of a little over 300. Lift is 9.53mm on one and 9.84 on the other. Not for use with Automatics. This is a big HP cam. Some torque will be sacrificed. Asking $175 for either one. Todd
