I bought them from a friend and I didn't have a chance to put them in so I don't know the milleage but I know they are used but almost new condition. The reason I'm selling is because I was going to put them on my CRX but I'm selling that so now I have to use for them. They are 1200 cams and 250 for the cam gears n I'm selling them for 500. I need the money for a house so who ever gets them is getting a good deal
