– COMPETITION CAMS 252XFI PRECISION SPECS: Features the 12-364-4 grind with 252°/266° Advertised Duration, 208°/217° Duration @ .050″, and a precision .477″/.472″ Valve Lift.
– 7.794″ HIGH ENERGY PUSHRODS: Set of 16 heat-treated steel pushrods with a 5/16″ diameter. You should buy these to prevent pushrod flex and maintain perfect rocker arm geometry under the stress of high-lift XFI lobes.
– TRUE DOUBLE ROLLER TIMING SET: Includes a high-strength double-row chain and heat-treated gears. This upgrade is 3x stronger than stock, preventing chain stretch and ensuring your engine’s timing stays exact for maximum EFI sensor accuracy.
– OPTIMIZED FOR FUEL INJECTION: The 113° Lobe Separation Angle is specifically tuned for EFI and TBI applications. It provides the stable manifold vacuum signal your sensors need while still achieving a significant power increase.
– MAXIMUM TORQUE OUTPUT: Engineered for a 1,300–5,300 RPM range, providing a massive increase in pulling power exactly where you need it for street performance and highway passing.

Description
Description
The XFI (Xtreme Fuel Injection) Advantage The Competition Cams 12-364-4 is the premier choice for late-model engine swaps or upgrading existing EFI systems like TBI or Crossfire. As part of the XFI series, this cam features the newest and quickest lobe profiles in the Xtreme family. These “fast-ramp” profiles are designed to provide a dramatic increase in torque and throttle response by getting the valves to peak lift faster. This is the definitive “area under the curve” cam for owners who want modern efficiency from a classic flat-tappet design.
Precision Valvetrain Geometry To ensure your engine’s valvetrain is perfectly aligned, we have included Competition Cams High Energy 7.794″ Pushrods. Correct pushrod length is critical for maintaining proper rocker arm geometry. These one-piece, heat-treated steel pushrods are engineered to withstand the faster ramp rates of the XFI cam, ensuring that every bit of lift is transferred precisely to the valves without deflection or power loss.
Rock-Solid Timing Accuracy To ensure your engine’s power remains consistent, this kit includes a True Double Roller Timing Set. Standard single-row chains are prone to stretching, which causes “timing drift” and robs you of torque. This heavy-duty double-row design is 3x stronger than stock, keeping your camshaft and crankshaft in perfect synchronization. This is critical for EFI engines to ensure the computer receives a stable mechanical signal.
Why This Kit is the Professional Choice The reason to buy this kit is complete valvetrain synchronization. Instead of mixing and matching parts that might not be compatible, you are getting a professionally curated package where every component is designed to work together. From the superior metallurgy of the lifters to the rigid strength of the pushrods and the rock-solid timing set, every part is a safeguard for your engine.
