GSC P-D Ford Voodoo Head Cross Plane Firing Order (Ported Head) Billet R3 Cams (Req Spring Upgrade)

These GSC Power Division R3 camshafts are specifically made for Ford Voodoo engines with the cross-plane firing order, designed to work with ported cylinder heads. The billet construction means they are machined from a solid piece of steel, offering a strong and durable foundation for improved engine performance. This isn't just a mild grind; these cams are intended for enthusiasts looking to extract more power from their Voodoo engine, particularly when paired with cylinder heads that have been ported to optimize airflow. You'll notice a significant change in how the engine breathes and performs at higher RPMs.

The R3 designation indicates a specific profile developed by GSC Power Division, focusing on maximizing power output for this particular engine configuration. Because these cams have a more aggressive lift and duration profile than stock, they require an upgraded valve spring kit to handle the increased forces and prevent valve float at higher engine speeds. It's crucial to ensure you have the correct spring kit installed to match these camshafts for reliable operation and to achieve the performance gains they offer. This upgrade is a key step for anyone serious about building a high-performance Voodoo engine.

When installing these camshafts, remember they are designed for ported heads, meaning the cylinder heads themselves have been modified to allow more air and fuel mixture into the cylinders and exhaust gases out. This synergy between the ported heads and the R3 cam profile is where the real performance potential is unlocked. While these cams are a substantial upgrade, they are not CARB approved and cannot be shipped to California. Always consult the manufacturer's installation guide for specific details regarding valve spring requirements and installation procedures.
