This Monster Powertrain Package is complete with all the features you need for a reliable Chevy 383 & Automatic Overdrive TH400 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 383 long block is a great plug and play choice for your small-block crate engine needs. You will receive your engine mostly pre-assembled with the intake manifold, carburetor, water pump, and distributor. The 4 bolt block holds a stronger Scat Nodular Iron crankshaft, quality 4340 forged rods, and hypereutectic dished pistons. Lastly the hydraulic 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.
