I'm learning what I can about this newly found Z. I don't have any background as to what has been done to the engine. It runs great with what seems to be good power, though I haven't really tested it. The sound/rumble is impressive. In my reasearching with this group on various topics I uncovered that my reverse lights not working could be the result of a header install. From the pics what could you tell me about the engine updates? Any way to tell if these are cheap headers or good? The Holley carb...anything else I might want to know. I've been an office guy too long, so wrenching stuff will be fun. Thanks guys.
