Hey guys, thinking bought selling some used go fast parts but not sure what they are worth? Obviously only what someone is willing to pay but I'd like to get a ball park value. Used carillos, arp main studs, ATS twin cp3(lbz) with lbz pump. Rods are from a broken crank engine, at a local shop to have checked. All is good. Main studs from same motor, and twin cp3 is still on my motor. What is the going rate now adays?
