ok.. I bought an 86 GN. I don't trust the tune in it because the chip was made by some shop in illonois in 2001. So my chip is over 10 years old and I want to replace it with a TT chip. Problem is that I don't know what kind of cam I have. The engine in my car had been rebuilt with ARP hardware, a double roller timing chain, and forged PISTONS, so I doubt the cam is stock. Is there a way to check what cam I have without ripping the engine apart to degree it? Can a dial indicator on a pushrod work? I took pictures of any markings I saw on the cam while I was doing an oil pan gasket. I'll post pics of that if it helps anything. Any help would be appreciated.

better edit that original post. I didn't want to sound like a liar or an idiot I'm just inexperienced. The previous owner had no idea the engine was rebuilt and I'm trying to find out all the mods on my own. I was told from people I showed that those pistons were forged. Trust me I'm no expert either. I've never first hand seen a forged anything to know what it looks like at a glance. This is the first modified car I've ever owned so I'm getting my knowledge built up.
