So, I found a local seller with an 07 SS for $2000. It has 135K, but it has a lifter tap.. Do you guys think the cam is bad too? Its really tempting to buy this!!

 

considering what they still sell for, the last 07 SS that was at a lot near me was around 8K. I would think at 2K you still have about 5 or 6K to fix it I would probably do it, but that's just me.
You should find out what a motor costs and install, I think you could still save money.
