The 5L381999-NP is a fully rebuilt and remanufactured 2005 Pontiac GTO LS2 engine motor, specifically designed for vehicles equipped with a 4-speed 4L65E automatic transmission. This engine is a powerhouse that delivers an impressive performance, making it a popular choice among car enthusiasts and automotive professionals alike.

The LS2 engine, originally produced by General Motors, is a 6.0L (364 cubic inch) V8 powerplant that delivers an astounding 400 horsepower and 417 lb-ft of torque. The engine block is made of aluminum, which not only reduces weight but also increases durability and longevity. The cylinder heads are also made of aluminum, featuring 2-valve, dual-overhead cam design with roller-finger lifters for smooth operation.

The rebuilt engine comes with a variety of upgrades and improvements to enhance its performance and reliability. The camshaft and lifters have been upgraded for improved valve timing and lift, resulting in increased horsepower and torque. The valve train components, such as the rocker arms, valve springs, and retainers, have been replaced for better performance and durability. The pistons and connecting rods have been inspected and replaced if necessary, ensuring proper engine balance and smooth operation.

The engine is fitted with a new oil pump, a high-performance water pump, and a new timing chain and belt kit for reliable operation and long-term durability. The cylinder bores have been honed to ensure a perfect seal between the piston rings and the cylinder walls, reducing oil consumption and ensuring smooth operation. The engine also features a high-performance, hydraulic roller-type camshaft, which provides improved valve control and increased performance.

The engine is equipped with a new set of high-performance spark plugs, ignition coils, and distributor cap for improved ignition and combustion. The cylinder heads have been ported and polished for improved airflow, which increases the engine's ability to breathe and deliver more power. The fuel injectors have been cleaned and tested for optimal performance, and the engine is equipped with a new fuel pump to ensure proper fuel delivery.

The engine is also equipped with a new set of gaskets, seals, and O-rings to ensure a proper seal between all the engine components, reducing the risk of leaks and maintaining engine performance. The engine is painted and detailed to a high standard, with all the components clean and shiny.

The 4L65E automatic transmission that this engine is designed for is a robust and reliable 4-speed transmission that delivers smooth and efficient power delivery. The transmission has been inspected, serviced, and rebuilt to ensure it operates at its peak performance. The clutch packs, valve body, and solenoids have been replaced as needed, and the transmission has been flushed and filled with fresh transmission fluid.

In conclusion, the 5L381999-NP is a fully rebuilt and remanufactured 2005 Pontiac GTO LS2 engine motor, designed for use with a 4-speed 4L65E automatic transmission. This engine is a high-performance powerhouse that delivers an impressive 400 horsepower and 417 lb-ft of torque, making it a great choice for anyone looking to upgrade their vehicle's engine or restore a classic muscle car. The engine and transmission have been thoroughly inspected, serviced, and rebuilt to ensure they operate at their peak performance, providing you with reliable and enjoyable driving experience.
