I have a 2011 Caprice engine, 6.0 liter, without DOD. It has LS3 heads and intake manifold, without accessories, just the intake. The engine is in excellent condition and has no issues. The engine fits directly on 2007 to 2016 models. The engine was previously installed on a 2004 Lumina. If you want it for a 2004 model, I can include the conversion harness and programmed computer for an additional 500 + 700. Tabby and Tamara are available if you install it at the workshop where the engine is located ✅
