M311 LS3 Cylinder Head Rect-Port Assembled

The M311 LS3 Cylinder Head Rect-Port Assembled from Frankenstein Engine Dynamics is a precision-engineered cylinder head designed for serious LS3 engine builders and performance enthusiasts. This fully assembled head simplifies the building process by eliminating the need to source individual components, valve springs, and pushrods separately. It is suitable for various applications, including high-revving naturally aspirated engines, stroker platforms, and setups for forced induction.

The cylinder head features a rectangular port architecture that optimizes airflow velocity and scavenging efficiency, enhancing volumetric efficiency and combustion chamber fill. With all valvetrain components, springs, and internal hardware pre-installed and set to factory specifications, this head reduces assembly time and minimizes potential fitment issues. The robust materials used in the valve seats are designed to withstand aggressive valve timing, high boost pressure, and extended heat cycles.

Engine builders looking for reliability and performance will find this cylinder head ideal for their projects. The precision machining and quality control from Frankenstein Engine Dynamics ensure that this head maintains tight tolerances and consistent performance across multiple units. This product is perfect for those aiming to achieve optimal power production across the RPM spectrum.
