I'm not sure of the miles but I saw it run before it was pulled. Also I sold the dizzy, harness, etc. It's mjust a long block and for a good offer i'll include the intake mani complete with injectors and throttle body. I need it gone asap, my phone is off and I need the money to get it back on! Best offer takes it this week!!!!!!!!!! block and head, z6, light weight crank pulley, aluminum adj. cam gear, intake mani with all the other parts to it!
