Need help !! North Alabama I traded for a 02 Ws6 with 25k miles a few weeks back. After driving it about 15 miles I started to hear a knocking sound from the engine. Its a pretty loud sound but it kinda sounds as if it coming from the pass side head. I have no idea what would make that kinda noise in the head. Also the guy I traded with said it had AFR heads, been cammed, ZO6 intake and throttle body, full SLP exhaust, and a NOS that he claims had never been used. Any ideas would be great or if someone was in my area of Gadsden, AL and wouldn't mind looking at it that would help me a ton. Thanks !!

Take the trans am plate off the front left passenger side head to see if they are AFR...They mark their heads on the front. The Z06 intake is just an Ls6 intake, and Im pretty sure the Corvette uses a different kind of tb so it might just be a ported stock throttle body. As for the knock it could be a lot of things. Sorry Im not a little closer to help out a little more.
