The Meziere WAM10020S is a high-performance water manifold designed specifically for Big Block Chevy (BBC) engines. This precision-engineered aluminum manifold features a large 20AN inlet for maximum coolant flow capacity, making it ideal for high-horsepower applications and racing environments where efficient cooling is critical.

Key Features:

• 20AN (-20) inlet fitting provides superior coolant flow compared to standard fittings
• Designed specifically for Big Block Chevy engine applications
• CNC-machined aluminum construction for lightweight durability
• Black anodized finish for corrosion resistance and professional appearance
• Direct replacement for stock water manifold with improved flow characteristics
• Accepts standard BBC cylinder head bolt patterns

This water manifold is an essential upgrade for BBC engines running high power levels, forced induction, or extended racing duty. The oversized 20AN inlet eliminates coolant flow restrictions and works seamlessly with high-capacity electric water pump systems and custom cooling setups.
