I have a factory set of springs from a 97 trans am. They have about 7k miles on them. I was going to install in my car but decide to sell the car. They are sitting in my garage taking space. I am asking $50 plus shipping. I also have a lt1 block with 15k miles that has been vatted & honed. It is stock bore and also comes with the stock rotating assembly. I am asking $450 obo
