I think my quote under the picture of my car somes up the performance of Bobs cam. My motor is the original stock balanced and blueprinted non ported 906 heads with his cam. The only mod is the compretion which is just under 11.0. But it idles like a six clynder and is so quite with the mufflers that I use that you can barely here it running. The car runs high 12's on a good pass with a 4.10 and a 4 speed. Last fall I was running my car at the local track, and after several runs of beating these big tire, huge cam loud teenage cars I took the hood off to show some people . And this one guy put a beer can on the air cleaner when it was running and said" Man that thing idles like the station wagon my grandma used to drive." So in a nutshell if you want a stock performing cam that works best with a stock motor I don't think their is a better choice anywhere.
