When I bought my lx about a week ago, the owner said it had a "high rpm" cam, but I really have my doubts as to the validity of this. Is there a way to tell besides opening up the engine to see? If I posted a video of the exhaust note on idle, would you guys be able to tell me? I dont want to buy a cam and discover it already has one. I wont be able to get track times for a few weeks, so I can go on that, and it has other mods (p/p heads, 3.73's) that might throw that off anyways.
