This Monster Powertrain Package is complete with all the features you need for a reliable LS3 376CI & Automatic Overdrive 4L65E Transmission from a researched and developed combination of components. You'll have all of the reliability that you would want from a good street cruising motor while still being able to have that power you need.

The complete Chevrolet 376 long block is a great plug and play choice for your crate engine needs. You will receive your engine mostly pre-assembled with the intake manifold, fuel injection system, water pump, and other accessories. The block holds a stronger crankshaft, quality forged rods, and Forged pistons. Lastly the hydraulic roller camshaft will give your Lead Foot motor that distinct idle tone. This engine offers you an incredible performance value - all you need to do is add the additional components with some fresh gas and then let her rip! Lead Foot stands behind every product built. To honor that, we are proud to offer an industry setting 2 year unlimited mileage warranty.
