Nope, Racer Brown is "old School" been around for many years and I don't mean any disrespect by the "old school" comment. His cams are very proven and many guys love his cam profiles. I've never ran one but I've heard a lot of people speak highly of them.
Scott Brown is Straight Line Performance:
http://www.buyracingparts.com/He's a younger guy, and very very well respected cam spec and builder for a lot of people here on Moparts. A year or so ago that's about all any one was running. He's a mopar guys and has a lot of knowledge on Mopars. Here is his number
(616-499-6223) , you can tell him about your car and motor and he will send you his recommendation for a cam. I've ran about 4 of his cams, great guy, great personal service, he's always gone out of his way for me.
He had an opportunity to go work for a company doing some really leading edge motorsports stuff so we lost his focus for about a year but he was still doing cams just wasn't doing much advertising. But that company went under so he back working for himself now for well over a year now.
If you call him, be sure and ask him about lifter and spring recommendations, hopefully your spring will work since they don't have but 20mins of run time on them.
