STAGE 3 HP Master Engine Rebuild Kit FITS: 1986-1992 Chevrolet SBC 350 5.7L V8 w/Stage-3 .480/.480 Lift HP Performance Cam & Flat-Top Pistons

Turn your Small Block Chevy into a street-eating machine with the Enginetech ES186R Stage 3 Camshaft. This is not a mild stock replacement; this is a serious performance upgrade designed for SBC 350, 327, 383 Stroker, and 400 engines that demand respect. If you are building a Saturday night cruiser, a bracket racer, or a muscle car that sounds as mean as it runs, this is the cam for you. Engineered to deliver substantial horsepower gains over factory profiles, the ES186R is the perfect choice for enthusiasts who want that classic "hot rod" sound and performance without breaking the bank on boutique racing brands. Let’s talk numbers, because this is where the ES186R separates itself from the pack. Boasting a balanced lift of .480” intake and .480” exhaust, this camshaft opens the valves significantly further than stock, allowing for massive cylinder filling and exhaust scavenging. This "Stage 3" geometry is optimized for the mid-to-upper RPM range (typically 2,200 to 5,800+ RPM). It is designed to breathe deep at high RPMs, making it an absolute monster for highway pulls and drag strip launches. Because of the increased lift and duration, this cam works best with an aftermarket intake, headers, and a slightly higher stall converter to really unlock its full potential. How is this going to feel in your engine? In a word: Aggressive. When you fire up your Camaro, Corvette, or Nova, you are going to get that distinct, loping idle that screams American Muscle. It’s that "choppy" sound that turns heads at every stoplight. On the road, the power delivery is explosive. While you might trade a tiny bit of off-idle smoothness compared to a stock cam, you get paid back with a rush of power that keeps pulling hard all the way to the redline. It makes the engine feel eager, responsive, and ready to run. Why should you buy the Enginetech ES186R? Because you want race-ready geometry with proven durability. Enginetech manufactures these shafts to precise tolerances, ensuring consistent timing events and long lobe life. You are getting a high-performance hydraulic flat tappet cam that delivers the same power numbers as the "big name" performance brands, but at a price that leaves you budget left over for tires and gas. If you are ready to stop driving a boring stock motor and start driving a true performance build, the ES186R is the upgrade you need.
