Great choice for street and race-oriented LS V8 engines. Extremely choppy idle that lets everyone know your LS means business. Works well for 6.0L LS and LS strokers with increased displacement. Recommend 3，000 rpm stall torque converter for best performance. Increases top end power with some sacrificing of low-end torque. A good fit for naturally aspirated or boosted applications. An aggressive cam that will lose some driveability on the street. Camshaft requires 3-bolt cam gear (later LS engines use a single cam bolt) Upgraded beehive valve springs， timing gasket set， and balancer bolt are included. Active Fuel Management must be deleted on GM truck and Impala applications. Custom engine management tuning will be required for best performance. Wake Your LS Up with Elgin’s Sloppy Mechanics Performance Camshafts The LS engine family is arguably the most popular engine family on the planet these days. You’ll find these compact pushrod V8 engines in everything from hot rods and muscle cars to classic trucks and more! Their swapability into just about anything， their simplicity， and large source of original applications means the LS engine family is easy on the project budget and that there are numerous upgrades and performance parts available for them. Many of the LS engine donor sources are GM truck applications. While performance is solid from the factory， GM’s trucks are designed for work and daily chores like hauling the family. As such， GM engineers designed the LS “Vortec” engine series in these trucks for a long life at relatively low engine rpm with an emphasis on torque. Obviously， these engines will run in your LS swap project as is， but one of the best “bang for the buck” upgrades you can do to your truck LS engine before it lands on those LS swap mounts in your project is an LS cam swap to something with a little more lift and duration. Elgin’s line of Sloppy Mechanics performance LS camshafts is the hot ticket for a Chevy 5.3 cam upgrade， especially if you’re considering additional performance upgrades like gears， high stall torque converter， or even a turbo! Consistent Quality and Machining for Long Life and More Horsepower We have a little secret to tell you. There are only a few companies out there that actually manufacturer their own camshafts from raw materials to finished product. Elgin Industries has been an automotive parts manufacturer and OEM supplier for over 100 years! Their ISO14001 facility handles these Elgin camshaft LS swap cams so you know the quality is there. Modern design coupled with Quality materials means these Sloppy Mechanics performance cam profiles make serious power without worry. The E-1841-P is considered Elgin’s “Stage 3” cam profile and is their most aggressive cam profile suitable for big-inch LS strokers and those looking for a very noticeable cam chop. The cam profile features .595-inch lobe lift with a split pattern duration of 296-degrees intake and 299 degrees exhaust. This equates to duration at .050-inch lift of 238/242. A lobe separation angle (LSA) of 112 degrees is EFI and carb friendly but may not create sufficient vacuum for accessories like power brake boosters and air conditioning. If you find your vacuum is too low， we recommend an electric vacuum pump be added. Suitable for naturally aspirated LS engines， this Elgin E1841P Sloppy camshaft it will be just at home in a 5.3 LS turbo build or your 6.0L LS stroked to 427ci. We recommend an aftermarket torque converter with a stall speed in the 3，000 rpm range and steeper (numerically higher) rear gear ratio. This cam’s power comes on in at the top end and will sacrifice some low-end torque. A Cam Swap Worth the Effort for Your LS Engine Adding this Sloppy Stage 3 camshaft to your LS is as straight forward as any other cam swap for the LS platform
