351c Ford X-Celerator

The WEIAND 351c Ford X-Celerator intake manifold is a high-performance, single-plane aluminum component designed specifically for 351 Cleveland engines and modified 2-valve head applications. This manifold is ideal for engine builders and performance enthusiasts looking to enhance their street and strip engine performance.

Engineered with optimized runner geometry and port velocity characteristics, the X-Celerator provides measurable gains in the mid-range to upper RPM band. Its aluminum construction with a natural finish allows for custom coating or anodizing, ensuring both performance and aesthetic appeal. The single-plane design promotes efficient combustion charge stratification while reducing low-speed signal noise.

This manifold is particularly beneficial for those restoring or upgrading vintage Ford 351C platforms, as it helps achieve improved intake velocity without compromising cross-scavenging benefits. Common applications include street performance builds, weekend bracket racing, and engine swaps where factory iron manifolds may hinder performance due to excessive weight and restrictive flow.
