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 for your Chevy.

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.

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 top-end horsepower. 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 even under high-load racing conditions.

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 rock-solid timing set and the matched spring and hardware pressures, every part is a safeguard for your high-performance engine.
