Ed -

Are you talking about John McWhirter? I knew all those guys, too. The RHS guys bankrolled Heffington to start Cam Dynamics. First time I met Mark was when they had the clandestine machining operation in the back of the sewing machine shop in Memphis. I got the #1 stocker cam Mark ever built. It was square lobed and would float the valves at about 5800 rpm. I also got one of the first 7000 series stocker cams to test and immediately changed from 4.56 gears to 5.87. Mark split with the RHS guys a few years later and in the breakup agreement the RHS guys got to use all of Mark's cam designs. That's how Comp Cams got started. McWhirter and Scooter were in charge of the cam company and Ivars still ran the engine shop. Ironically, Mark left Crane to start Cam Dynamics and it circled around and Crane bought CD. Mark and I used to have some great conversations! I was a philosophy major in school and Mark was attracted to every weird idea in the universe, so we would talk for hours. Remember the great t-shirts CD would print? I always liked the hippie flowered ones.

What was the guy's name that started RHS with Ivars? I can remember his face, but can't grab the name. We always said he was part of the Memphis mafia.
