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 Chevy.

Precision Timing and Strength To ensure your engine’s power remains consistent and your timing stays rock-solid, we have included a True Double Roller Timing Set. Standard single-row chains are prone to stretching over time, which causes “timing drift” and robs you of critical low-end torque. This heavy-duty double-row design is 3x stronger than stock, keeping your camshaft and crankshaft in perfect synchronization. This is especially vital for EFI engines to ensure the computer receives a stable and accurate mechanical signal for peak efficiency.

Modern Efficiency and Drivability With a 1,500–5,500 RPM operating range, this camshaft targets the mid-range power that makes a street vehicle feel truly fast. The wider 113-degree lobe separation angle is the key to its success; it provides the clean, stable manifold vacuum signal that computer-controlled systems need to function properly. You should buy this kit to ensure your vehicle maintains a manageable, rhythmic performance idle and excellent throttle response while still achieving a massive jump in overall performance.

Superior Valvetrain Integrity To handle the aggressive ramp speeds of the 260XFI, this kit features Premium Redline High-Performance Lifters. These hydraulic flat-tappet lifters are manufactured with advanced metallurgy to withstand the mechanical stress of high-lift lobes. Featuring precision-machined oiling ports, they ensure a constant film of lubrication between the cam and lifter face. This is the single most critical factor in ensuring a successful break-in and long-term durability for your high-performance build.
