– COMPETITION CAMS 268XFI ACCURATE SPECS: Features the 12-366-4 grind with 268°/280° Advertised Duration, 224°/231° Duration @ .050″, and an impressive .515″/.507″ Valve Lift.
– THE “XFI FEEL” – EXPLOSIVE TOP-END POWER: This cam is designed for the driver who wants to feel the engine “come alive” at 2,000 RPM and pull hard all the way to 6,000. You should buy this to get that aggressive surge that makes a street car feel like a track-ready machine.
– HIGH-PERFORMANCE SPRINGS & STEEL HARDWARE: Includes a matched set of valve springs specifically engineered for the 268XFI profile, paired with heavy-duty steel retainers and locks. You should buy this to ensure your valves close as fast as the aggressive cam profile demands, preventing destructive valve float at high RPM.
– 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 power delivery and EFI sensor accuracy.

Description
Description
The XFI (Xtreme Fuel Injection) Advantage The Competition Cams 12-366-4 represents the top tier of streetable performance for late-model engine swaps or upgraded EFI systems. As the most aggressive member of the street XFI series, this cam is designed to take full advantage of high-flow intake manifolds and 1.6 ratio rocker arms. By getting the valves to peak lift faster and keeping them open longer, this “fast-ramp” profile creates massive “area under the curve” horsepower. If you want the most powerful flat-tappet cam that still maintains fuel-injection synchronization, this is the one to buy.
High-RPM Control and Protection The final piece of this performance puzzle is the High-Performance Valve Spring Kit. Standard factory springs lack the seat pressure required to control a high-lift cam like the 268XFI, which can lead to destructive valve float. This kit features springs paired with precision-machined steel retainers and heat-treated locks, providing the high-tensile strength needed to keep your valves under control while protecting your engine from catastrophic failure as you approach the 6,000 RPM mark.
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 and high-lift stress of the XFI cam, ensuring that every bit of lift is transferred precisely to the valves without deflection or power loss.
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 matched spring and hardware pressures, every part is a safeguard for your high-performance engine.
