– COMPETITION CAMS 260XFI ACCURATE SPECS: Features the 12-365-4 (XFI 260H-13) grind with 260°/272° Advertised Duration, 216°/223° Duration @ .050″, and a high-performance .499″/.493″ Valve Lift (calculated with 1.6 rockers).
– HIGH-PERFORMANCE SPRINGS & STEEL HARDWARE: Includes a matched set of valve springs specifically engineered for the 260XFI 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.
– 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.
– OPTIMIZED FOR FUEL INJECTION: Features a 113° Lobe Separation Angle designed for EFI applications. This provides a steady vacuum signal for your sensors, ensuring your computer stays “happy” while you gain a massive performance boost.

Description
Description
The XFI (Xtreme Fuel Injection) Advantage The Competition Cams 12-365-4 is the premier choice for late-model engine swaps or upgrading existing EFI systems like TPI 350 engines. As a specialized member of the XFI family, it features the newest and quickest lobe profiles available, designed specifically to work with 1.6 ratio rocker arms. This translates to more “area under the curve,” providing a dramatic increase in torque and horsepower without the drivability issues common in older designs. You should buy this cam to get the absolute most out of your fuel-injected engine.
High-RPM Control and Protection The final piece of this performance puzzle is the High-Performance Valve Spring Kit. Standard factory springs often lack the seat pressure required to control a performance cam with faster ramp rates, which can lead to 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 at higher RPMs.
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 higher lift 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 engine.
