I'm new here so forgive me if this thread belongs in another section. I've had my 86 SS for over a year and a half now that I got at auction. I bought it sight unseen but got lucky as it looks and runs great. It has a few mods that I know of, but being I participated remotely in the auction, I didn't have the opportunity to ask the seller about it. The thing I wanted to find out is if anyone can tell me whether they think it has an aftermarket cam (I have video). Aside from taking the engine apart, which I don't have the knowledge, facilities, or physical capabilities to do so, can anyone tell by listening to the idle whether its stock or not?
