Through some trading I wound up with a crate DOHC Z34. What do I look for (and where to find it) to tell exactly what I have? Like year, stuff like that. I am going to try to sell it on ebay and I might as well have some answers before I post it. Haven't seen one on ebay since I aquired mine so I have no idea what to ask. I have seen some complete used ones but not a new crate long block. Thanks.
