Description
Description
The XFI (Xtreme Fuel Injection) Advantage The Competition Cams 12-364-4 is the ultimate choice for late-model engine swaps or upgrading existing EFI systems. As part of the XFI series, this cam features the newest and quickest lobe profiles in the Xtreme family. These “fast-ramp” profiles are designed to provide a dramatic increase in torque and throttle response by getting the valves to peak lift faster. This is the definitive “area under the curve” cam for Chevy owners who want modern efficiency from a classic flat-tappet design.
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 Timing and Strength To ensure your engine’s timing remains rock-solid, 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 horsepower. This heavy-duty double-row design is 3x stronger than stock, providing the mechanical accuracy needed to keep your camshaft perfectly synced with your crankshaft even under high-load 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 True Double Roller Timing Set and matched springs, every part is a safeguard for your engine.
