Description

The XFI (Xtreme Fuel Injection) Advantage The Competition Cams 12-367-4 is the flagship of the XFI street series, designed specifically for late-model engine swaps or heavily modified fuel-injected systems. Ground with faster-opening and more efficient “fast-ramp” profiles, this camshaft is engineered to work in harmony with 1.6 ratio rocker arms. This specialized design creates massive “area under the curve,” providing a dramatic increase in mid-to-high range power that traditional cam grinds simply cannot match. You should buy this kit to push your Small Block to its absolute mechanical limit while maintaining perfect electronic synchronization.

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 280XFI 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 under the stress of high-RPM pulls, 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 and horsepower. This heavy-duty double-row design is 3x stronger than stock, keeping your camshaft and crankshaft in perfect synchronization. This is critical for fuel-injected engines to ensure the computer receives a stable mechanical signal throughout the entire power band.

Superior Valvetrain Integrity To handle the high-lift and aggressive ramp speeds of the 280XFI, this kit includes Premium Redline High-Performance Lifters. These hydraulic flat-tappet lifters are manufactured with advanced metallurgy to withstand the extreme mechanical stress of high-output lobes. Precision-machined oiling ports ensure a constant film of lubrication between the cam and lifter face, which is the most critical factor for a successful break-in and long-term durability in a high-performance engine build.
