Saw this cam at the Peterson musuem in L.A. Was in a scene from the past of an old Hot Rod Garage of the 40"s and 50's. Look at the lobes on the cam...there are double lobes and it would appear this would open the valves twice as often as a std 4 cycle cam. The cam appears to be a small block chevy, but I'm not positive. Any body out there ever seen a cam with a grind like this??
