The ATK High Performance Engines DCW4 is a professionally remanufactured crate engine designed for 2001-2007 Chevrolet and GMC trucks, SUVs, and vans equipped with the 4.3L/262 cubic inch V6 engine. This is a remanufactured engine with zero miles, offering reliable performance and OE-quality specifications at a cost-effective price point.

Remanufacturing Process:

• Completely disassembled and put through a rigorous process where all heads, blocks, cranks, and cams are machined and wear parts are replaced
• Reverse engineered to find and remove any factory original defects
• Individually tested after assembly to assure compression, oil pressure, and water jacket integrity
• Built to OE horsepower and torque specifications

What's Included:

The engine comes as a long block assembly and requires transferring all original components over to make it work properly. The DCW4 block assembly does not come with external tinware, and gaskets are not included.

Break-In Procedure:

Use conventional or break-in oil (non-synthetic) for the first 600 miles of operation. At 600 miles, change the engine oil and filter using conventional oil. After the first 5,000 miles of service, synthetic engine oil may be used.

This remanufactured crate engine is an ideal solution for high-mileage rebuilds or engine replacements, delivering factory-grade performance with the reliability and quality ATK is known for.
