2000 Corvette ls1 with the bstwing pan. Only 40k miles when it was pulled. Motor was pulled almost 10 years ago after a front end electrical fire. As seen by the melting on the oil fill tube. Motor internally is great. No ring grove(head was pulled to check for corrosion)Sat in a humid garage for a long time. Turns over easy. Just needs a good cleaning and fresh gaskets.853 Heads.
