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 like Crossfire or TBI. 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 and keeping them there longer. This is the definitive “area under the curve” cam for Small Block owners who want modern efficiency from a classic flat-tappet design.
EFI-Optimized Performance Unlike standard performance cams that can confuse a computer’s MAP sensor with a choppy idle, the 12-364-4 features a wider 113-degree lobe separation angle. This provides a smooth, stable idle and a clean vacuum signal that EFI systems require to function correctly. You get a massive jump in power across the 1,300–5,300 RPM range without sacrificing the drivability or idle quality needed for a street-legal performance vehicle.
Superior Valvetrain Integrity To handle the aggressive opening rates of the XFI lobes, this kit includes Premium Redline High-Performance Lifters. These lifters are manufactured using advanced metallurgy to withstand high-velocity mechanical stress. Featuring precision-machined oiling ports, they ensure a constant film of lubrication between the lobe and the lifter face—the most critical factor for a successful break-in and long-term durability in your Chevy.
Why This Kit is the Professional Choice By purchasing this matched pair, you are ensuring your valvetrain is synchronized for performance and longevity. We have paired the precision engineering of Competition Cams with Redline lifters to ensure your engine performs at its peak. This kit provides the high-lift technology of a modern build with the mechanical reliability of a classic flat-tappet system.
