The Ultimate High-Output Transformation for Late-Model 302s If you want your 1987-1995 5.0L Windsor to do more than just cruise, this is the kit that delivers the muscle. This Stage 3 Master Rebuild Kit is a comprehensive high-performance package specifically for non-roller applications. Whether you're building a street-strip Mustang or a high-winding truck, this kit provides the high-compression foundation and aggressive valvetrain needed to leave the competition in the rearview mirror. 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 a mild upgrade; it’s a heavy-hitter featuring a massive .498"/.520" lift and a precision 224/234 duration. Optimized for Non-EFI engines, this cam shifts the power band upward, delivering a violent surge in mid-to-upper range horsepower. It produces that legendary, choppy muscle car idle that sounds incredible through performance exhaust and lets everyone know your Small Block Ford is built for war. A Hard-Hitting Drive with Serious Top-End Punch Installing the Enginetech ES1141R completely transforms the "soul" of your engine. You’ll feel a massive increase in acceleration as the RPMs climb, with the dual-pattern duration ensuring the engine 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. This is the perfect match for those running 3.55 or 3.73 rear gears who want a car that feels alive. Why You Should Buy: Synchronized Power and Pro-Grade Protection A Stage 3 cam requires an oiling system that can keep up. 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 kit for the ultimate blend of aggressive sound, raw power, and ironclad reliability.
