I have a 2010 Ly6  and 2007 4l80e for sale that I have held onto for a project that I don't have time for right now. The motor I was told was a GM test motor and only has several hours of dyno time on it and it has never been in a vehicle. I bore scoped it when I bought it and it looks like a brand new engine inside. It now has a DOD/VVT delete kit,  236/236 112 comp cam, and a GM musclecar oil pan on it. The Ly6 is the best 6.0 you can buy and it has 823 ls3 heads. It is often the choice for performance builds and is more or less an ironblock ls3.  The transmission is a 2wd 2007 4l80e that is bone stock and has right under 100,000 Miles on it. It was pulled out of a running driving truck . I hate to sell, but I am building a house and don't have time to work on a project right now. No low ballers. If it doesn't sell I will just hang onto it. I will sell motor and trans seperate if motor sells first. If you have any questions give me a call at 785-737-6209. Thanks
