429/460 Ford Stealth

The WEIAND 429/460 Ford Stealth intake manifold is designed for serious big-block Ford performance builders who require efficient air delivery while maintaining underhood clearance. This manifold is particularly suited for enthusiasts running 429 and 460 cubic-inch engines in various applications, including street, strip, and marine environments.

Featuring a square-bore dual-plane design, the Stealth manifold optimizes low-to-mid range torque while supporting higher RPM power bands typical of big-block stroker and displacement-enhanced builds. Its compact profile ensures compatibility with modern ignition systems and fuel management hardware, while the cast aluminum construction offers thermal stability and weight savings compared to iron alternatives.

This manifold is ideal for Ford big-block restorations, hot rod builds, and marine engine swaps that demand factory-compatible bolt-on performance without the need for custom fabrication. Its design allows for reliable throttle response and efficient airflow, making it a valuable addition to any performance-focused project.
