Scampin!!!!!!

cleaned the car and drove it today, planned on heading over the local show because I was off today from work. I start the car up and a cloud of white smoke comes out of the exhaust and now i have quite the loud rod knock. Not sure what Im gunna do. Im gunna take the car off the road soon and Im strongly considering buying a crate 408 to just drop in over the winter and call it a day.
