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.

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 280XFI, 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 6,400 RPM mark.

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.

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 rigid strength of the pushrods and the matched spring and hardware pressures, every part is a safeguard for your high-performance engine.
