The engine was running untill 5or 6 month ago, nothing wrong. Engine includes block, head, intake manifold all assambled(sp) just like it came from the car. I wanted to use it and put the ZC head on it for more hp on my Civic, but I went the SOHC turbo way so I might as well sell it. It is price to sell quick not 'cause there is anything wrong with it.
