Full set of custom Ross pistons, pins, and Total seal ring package. Everything is brand new. I had ordered these and then discovered that the LS7 block would need to be bored to larger size. Listed below is the piston info. I have all of the paperwork if you do not see any of the info you are looking for. My mistake is your gain. The complete package was $ 1438.46 at my door. I will take $1100 and pay UPS ground freight within the US.
