The Ultimate Street/Strip Transformation Take your classic Ford 302 to the next level with a kit designed for the enthusiast who wants more than just a "stock" feel. This Stage 3 Master Rebuild Kit is a comprehensive high-performance package for 1967-1985 5.0L Windsor engines. Whether you are building a weekend warrior Mustang or a high-performance Chevy-chaser, this kit provides the high-compression foundation and aggressive valvetrain needed to dominate the street. The Power of the Enginetech ES1141R Stage 3 Camshaft The heart of this build is the Enginetech ES1141R Stage 3 Performance Camshaft. This isn't your average RV cam; it features a heavy-hitting .498"/.520" lift and a precision 224/234 duration. It is specifically engineered to shift the power band higher, delivering a violent surge in mid-to-upper range horsepower. This cam produces a noticeable, choppy performance idle that sounds incredible through headers and lets everyone know your Small Block Ford means business. A Hard-Hitting Drive with Serious Top-End Punch Installing the Enginetech ES1141R completely transforms the personality of your engine. While it maintains enough vacuum for street use, you’ll feel a massive increase in acceleration as the RPMs climb. The dual-pattern duration ensures that the engine doesn't just "breathe"—it screams through the mid-range. It replaces that sluggish factory feel with a high-winding, athletic "snap" that pulls relentlessly all the way through the gears, making it the perfect match for 3.55 or 3.73 rear gears. Why You Should Buy: Synchronized Power and Pro-Grade Protection A high-performance cam requires a professional-grade oiling system to survive. This kit upgrades your engine with a High Volume Oil Pump, providing the extra pressure needed to protect your bearings under high-RPM stress. Every component, from the flat-top pistons to the true double roller timing set, is synchronized to work in perfect harmony. Rebuilding your engine is a lot cheaper than buying a new truck—invest in this Stage 3 kit for the ultimate blend of aggressive sound, top-end power, and ironclad reliability.

• ENGINETECH ES1141R STAGE 3 PERFORMANCE CAM: Ground for .498"/.520" lift and 224/234 duration to unlock massive top-end horsepower. This cam delivers that legendary "loping" muscle car idle and a power band that explodes at 2,500 RPM, giving you the aggressive sound and feel of a true street-strip machine.
• HIGH-COMPRESSION FLAT-TOP PISTONS: Don't let power leak away through low-compression dished pistons. These precision units maximize cylinder pressure, creating a violent combustion event that translates into instantaneous throttle response and a heavy-hitting torque curve that you can feel in the seat of your pants.
• TRUE DOUBLE ROLLER TIMING SET: High-lift cams put massive stress on your timing gear. This kit includes a heavy-duty double-row chain system that provides absolute timing precision. It eliminates the "timing flutter" common in stock chains, ensuring your ES1141R cam stays perfectly in sync for maximum performance.
• HIGH VOLUME OIL PUMP: Speed requires protection. This upgraded pump delivers increased oil volume to your critical rod and main bearings, maintaining life-saving pressure during high-RPM pulls. You should buy this to ensure your high-performance investment stays lubricated and bulletproof.
• COMPLETE MASTER GASKET SET: Build it once and build it right. We provide a full set of premium-material gaskets and seals that are engineered to handle the increased heat and cylinder pressure of a Stage 3 build. Experience a perfect, leak-free seal that keeps your engine bay clean and professional.
• FULL BEARING & RING PACKAGE: This isn't just a "patch" job—it’s a total restoration. Featuring high-grade main, rod, and cam bearings paired with premium rings, you are restoring the "heartbeat" of your 302 to better-than-factory specs for superior vacuum and longevity.
• MATCHED PERFORMANCE LIFTERS: Engineered to handle the aggressive ramp speeds and lift of the Stage 3 profile. These lifters provide the stability needed to prevent valvetrain float at high RPM, giving you a smooth, synchronized, and reliable top-end that can handle the heat.
• OPTIMIZED FOR NON-EFI 1967-1985 302: This kit is the ultimate no-compromise solution for carbureted Ford 5.0L engines. It is a true "bolt-in-and-go" performance system that gives you the rowdy idle and high-speed pull you want without needing a computer to manage it.
• WHY YOU SHOULD BUY: This is the most comprehensive, expertly matched performance kit on the market. You aren't just buying parts; you're buying a perfectly synchronized horsepower system that saves you time and money by ensuring every component works together to dominate the street.
