Erson cam

I have an Erson cam that I love. 410" SB, 232/[email protected], 104 LSA ground 3 degrees advanced - .520 lift with Rhoads lifters. It idles choppy but smooths right out when cruising. My 67 Barracuda turned 12.35 and 107 at Las Vegas. I got 15 MPG driving down from Carson City. Im old 71 and broken so I am selling it. Just to hard to work on cars now.
