I picked up the 97 cams used. Then I found out that I broke an exhaust cam when my car broke down so I had to end up buying more cams. The only exhaust cams I could find at the time were a set (4) of 99/01s. So now I've got those 99/01s, 97 intakes, and 04 intakes that won't be going in the car. I'm planning on selling them when the car gets done so if anyone wants to buy them let me know. I don't plan to sell them to make any money off of them, but to just get my money back that I spent to buy them.
