BBC Crosswind Intake Manifold - Satin

The BBC Crosswind Intake Manifold - Satin from Professional Products is the engine builder's answer to maximizing big-block Chevy breathing efficiency and overall performance. Designed for serious enthusiasts who demand both reliability and flow improvement, this crosswind-style manifold replaces restrictive factory designs with optimized runner geometry that promotes even air distribution across all cylinders. Whether you're building a street engine, truck platform, or mild performance application, the Crosswind delivers the foundational airflow gains needed to unlock your BBC's true potential without requiring extensive head porting or expensive carburetor tuning.

Professional Products engineered the Crosswind design to minimize dead spots and turbulence that plague traditional log-style manifolds, resulting in improved cylinder-to-cylinder fuel distribution and more consistent combustion across the board. The satin finish protects against corrosion while maintaining a professional appearance under the hood, and at 18.8 pounds, the manifold's lightweight construction reduces underhood weight without sacrificing structural integrity or thermal stability. The crosswind configuration's symmetrical runner paths ensure balanced airflow velocity, which directly translates to cleaner idle characteristics, better throttle response, and measurable improvements in mid-range torque—the power band most drivers actually use on the street or strip.

This manifold is ideal for big-block Chevy platforms spanning 396 to 502 cubic inches, making it a practical choice for restorations, hot rods, and engine swaps where factory equipment falls short. Installation is straightforward for those with basic mechanical competency—no cutting, welding, or extensive modifications required on standard BBC blocks. The 11.3 x 6.6 x 23.4-inch envelope fits within typical engine bay constraints, though clearance verification is recommended before purchase, particularly in tight vintage chassis or with certain carburetor configurations. Pair the Crosswind with quality fuel delivery and proper jetting to realize its full potential and ensure your BBC runs strong and efficient across the entire RPM range.
