The BTR Truck Norris has become the default answer for 1999-2013 Gen III/IV LS truck engines because its 212/22X duration and .552/.552 lift on a 107 LSA deliver a noticeable chop at idle without requiring a converter swap. Owners report that the cam behaves well with stock torque converters, which is rare for a grind this aggressive. The beehive spring kit included in this package provides adequate seat pressure for the .552 lift without needing dual springs or machine work to the heads.

Dyno testing from BTR shows power and torque gains across the entire curve compared to their earlier V2 truck cams, which means the cam pulls from just off idle all the way to 5,800 RPM. The 3-bolt pattern fits later LS engines, but if your engine uses a 1-bolt cam, you will need a separate conversion kit. This version includes the cam, springs, and seals — no pushrods or lifters, so budget for those separately if your build doesn’t already have fresh hardware.

Real-world owners report that the idle sound lands somewhere between a mild street cam and a full race grind, with many noting that the chop is aggressive enough to turn heads at stoplights. One owner ran the cam for 2,000 miles in a 2012 GMC 2500 L96 and reported a noticeable power increase, though tuning was required to eliminate surging at low RPM. If you want the signature BTR idle and strong mid-range pull in a package that doesn’t force a converter upgrade, this kit earns the top spot.

The TSP Chopacabra rounds into the ring with 214/222 duration and .550/.550 lift on a 108 LSA, designed specifically for 4.8, 5.3, 5.7, and 6.0 cathedral-port engines. Texas Speed claims a 65-plus horsepower and 25-plus foot-pound gain at the crank under dyno testing, which makes this one of the strongest out-of-the-box gains in the mid-range segment. The kit comes with .560-lift beehive springs, valve seals, and OE replacement pushrods, so you get everything except lifters and timing hardware in one box.

What sets the Chopacabra apart is its factory torque converter friendliness. Despite the aggressive grind, it idles with a nasty chop while maintaining enough vacuum to keep accessories happy. The operating range starts at 1,200 RPM and extends to 6,500 RPM, which is a wider band than many cams in this lift range. Owners who installed this in 5.3 Tahoe and 6.0 Silverado builds report that the cam pulls hard from a stop without the boggy feeling that plagues larger grinds on stock converters.

One owner who paired the Chopacabra with a DOD delete swap in a 5.3 Tahoe dyno’d 390 rear-wheel horsepower and reported that the truck could haul a Mustang on a trailer with passing power to spare. Another owner noted fuel economy improvement from 14-15 MPG to 17-19 MPG after tuning, which is counterintuitive for a cam this aggressive but reflects the efficiency gains from reduced pumping losses at cruise. The kit requires tuning and, on 2007-2013 engines, a timing gear and lifter swap, but the results justify the extra effort.

This Dynosty-assembled kit takes the proven BTR Truck Norris cam and wraps it with everything you need for a complete swap: the camshaft, BTR SP011 .560 beehive springs, valve seals, pushrods, Delphi lifters, GM lifter trays, a cam install kit, and head gaskets for 4.8, 5.3, and 5.7 LS engines. The all-in-one approach eliminates the piecemeal shopping that causes most cam swap delays, and the inclusion of Delphi lifters removes the weakest link in many budget builds.

The Delphi lifters are a significant upgrade over stock LS units because they handle the aggressive ramps of the 212/22X 107 LSA profile without bleeding down at high RPM. The kit also includes GM lifter trays, which prevent the lifters from rotating and ensure consistent oiling to the roller wheels. Owners report that the labelled packaging and straightforward instructions make this a viable weekend project for someone with basic mechanical experience and a torque wrench.

Another owner noted that the kit included everything except a timing chain and oil pump, which are wear items worth replacing during any cam swap. The only catch is that VVT engines and DOD/AFM engines require separate delete kits — the base package assumes a non-VVT, non-DOE block. If you want a no-surprises, single-box solution for a 1999-2013 LS truck, this kit is hard to beat.

This variant of the BTR Truck Norris adds pushrods to the spring-and-seal package, making it a more complete solution for builders who already have lifters and timing hardware. The cam specs remain identical — 212/22X duration, .552/.552 lift, 107 LSA — so the power curve and idle character are the same as the base kit. The inclusion of pushrods saves a separate purchase and ensures the valvetrain geometry stays within spec for the .552 lift.

Owners consistently praise the sound and drivability balance of this cam. One owner running it in a 2005 Sierra 5.3 with a Monsoon intake and MBRP catback reported a throaty deep tone with excellent chop, and noted that the truck felt noticeably quicker even before tuning. Another owner who installed it in an LS-swapped 1993 Sierra called it a transformative upgrade that made the truck fun to drive every day. The cam pulls strongest from 4,500 to 6,500 RPM, which means automatic transmissions should be set to shift at or above 5,500 RPM to stay in the powerband.

The kit requires either a 3-bolt conversion on older engines or a VVT delete on VVT-equipped engines. Owners also note that the cam is noticeable at stoplights — the chop is real and draws attention. If you are comfortable with the extra fabrication for VVT or 1-bolt conversions, this pushrod-included kit delivers the same BTR magic with one fewer part to order.

The Sloppy Mechanics Stage 2 cam from Elgin is designed for builders who want a lope that is impossible to ignore. The 228/230 duration and .585/.585 lift on a 112 LSA produce a muscle-car idle that announces itself from half a block away. This cam is not for the faint of heart or for anyone trying to keep their truck looking stock — the chop is aggressive enough that people will ask what is under the hood at every stoplight.

The .585 lift pushes beyond what standard beehive springs can reliably control, so this kit includes upgraded springs and seals rated for the additional pressure. Elgin’s manufacturing quality on the core is solid for the price point, and the cam fits all Gen 3/4 LS engines including LS1, LS6, LS2, LQ4, and LQ9. The 112 LSA is wider than the BTR’s 107, which helps maintain slightly better vacuum for accessories, but the increased duration means this cam wants a 2,600-2,800 RPM stall converter to perform properly. Running it with a stock converter will result in a soggy bottom end and poor drivability around town.

One owner noted that the cam made excellent power under boost and called it the best budget cam for a forced-induction LS build. Another owner reported that the intake valves contacted the pistons after installation, which suggests that piston-to-valve clearance must be verified — this is not a drop-in cam for engines with stock pistons and no fly-cut reliefs. If you have a built bottom end or are planning a boosted setup, the Sloppy Stage 2 delivers the sound and top-end rush that weekend warriors crave.

The TSP 228R is the cam of choice for LS builders who want a proven street/strip profile that makes 45-50 rear-wheel horsepower gains on a 5.3. The symmetrical 228/228 duration on a 112 LSA with .600/.600 lift pushes this well into dual-spring territory, and Texas Speed includes a .660 dual spring kit with PAC Racing polished springs, titanium retainers, hardened seats, and new valve stem seals. The kit also includes a Michigan Motorsports gasket set covering the crank bolt, water pump gaskets, timing cover gasket, and front seal — everything to button up the front of the engine.

The 112 LSA brings the powerband lower in the RPM range compared to a tighter lobe separation, but 228 degrees of duration still demands a larger-than-stock stall converter in automatic cars. Tuning is mandatory in both automatic and manual applications. Owners report that the cam holds up well under sustained use, with one owner logging 580 miles without issues and reporting improved highway fuel economy. The titanium retainers reduce reciprocating mass, which allows the valvetrain to track the cam profile more accurately at high RPM.

The dual spring setup provides the safety margin needed for .600 lift, and the included gasket set simplifies the front cover reseal during installation. One owner did report a failed cam lobe traced back to a bad lifter, which underscores that high-lift cams magnify any weakness in the lifter set. Budget for fresh lifters and a timing chain when installing this kit. For a naturally aspirated 5.3 that sees track time, the 228R delivers the powerband and valvetrain stability of a professional race prep in a DIY-friendly package.

The COMP Cams CL12-242-2 is a flat-tappet hydraulic cam designed for Gen 1 small-block Chevys — the 262 through 400 cubic inch engines that predate the LS family. The Xtreme Energy profile uses faster-opening lobe ramps to increase area under the lift curve without increasing peak lift beyond .477/.480 inches. The 1,600-5,800 RPM operating range and 110-degree LSA give these classic small-blocks a strong mid-range punch without requiring a full race converter.

This kit includes the camshaft, a set of lifters, assembly lubricant, and instructions. The included lifters are essential because flat-tappet cams require precise lifter face mating — reusing old lifters on a new flat-tappet cam is a guaranteed failure. The 224/230 duration at .050 is aggressive for a flat-tappet grind and produces a noticeable exhaust note, but owners report that it maintains enough vacuum for power brakes when paired with an aftermarket intake and headers. The kit fits Chevrolet 262, 265, 267, 283, 302, 305, 307, 327, 350, and 400 engines, but does NOT fit LT1/LT4 or factory roller blocks from 1985 and newer.

One owner installed this in a 350-powered El Camino and reported a nice rumble with a solid horsepower increase. Another owner noted that the kit worked as advertised but recommended going bigger if the build had a 2,000-plus RPM converter. A critical warning from a 1992 Chevy 350 TBI owner: the stock computer cannot handle the longer duration, resulting in rough running and rich fuel trims. This cam works best with a carburetor or aftermarket EFI system, not a factory TBI computer.

The Edelbrock 2102 Performer-Plus cam is the mildest grind in this lineup, with 204 degrees intake and 214 degrees exhaust duration at .050 lift and valve lifts of .420 and .442 inches. This is not a cam that will produce a loping idle or a rowdy exhaust note — it is designed to work as a direct drop-in upgrade for a stock GM V8, delivering a noticeable but not dramatic power increase across the low and mid-range. The 112-degree lobe separation angle preserves manifold vacuum for power brakes and accessories.

This cam is part of Edelbrock’s Performer-Plus package, which is intended to match their Performer intake manifolds for a coordinated street performance system. Owners who paired this cam with an Edelbrock intake and carburetor report a huge improvement over the stock cam, with strong pull from idle and improved throttle response from the secondaries. One owner installed it in a stock 1970 C10 350 and noted that the truck ran better than it had in years, pulling strong without any drivability issues. Another owner emphasized that this kit is not for those who want a lope — it is for those who want a smooth, powerful daily driver.

Quality control has been a concern in some batches. One owner reported a defective cam that sounded horrible after the 30-minute break-in process, and others noted noisy lifters after break-in despite using proper break-in oil. The 2,500 RPM for 30 minutes mandated during break-in is nerve-wracking on a freshly rebuilt motor, but owners who followed the procedure reported good long-term results. If you need a drop-in upgrade for a vintage truck or muscle car that stays on the street, the 2102 is a proven choice — just inspect the cam lobes carefully before installation.

This JAVOUKA camshaft set is a direct OEM replacement for the Chrysler 3.6L Pentastar V6, not a performance upgrade. The four-piece set (part numbers 5184377AG, 5184378AG, 5184379AG, 5184380AG) fits a wide range of 2011-2016 Chrysler, Dodge, Jeep, and RAM vehicles including the RAM 1500, Grand Cherokee, Wrangler, Challenger, Charger, Town & Country, and Promaster. If your 3.6L Pentastar has a ticking or misfire traced to cam lobe wear — a known issue on early Pentastar engines — this set provides an affordable way to replace all four cams without going to the dealer.

The cams are made of metal with an anti-corrosion surface treatment and are machined to match the OE specifications. Owners report that the parts fit perfectly and work like factory replacements, with several noting that the cost of the four-cam set is roughly equivalent to what a dealership charges for a single cam. One owner who was hesitant about aftermarket camshafts installed these in a 2014 Town & Country 3.6L and reported that the engine ran smoothly afterward. Another owner with a 2015 RAM 1500 put over 27,000 miles on the set in courier use and reported no performance degradation.

The kit does not include instructions, so professional installation or a factory service manual is strongly recommended. Timing tools are required to set the cam timing correctly, and the job involves removing the intake manifold, valve covers, timing chain tensioners, and chain guides. If you are facing a Pentastar cam failure, this set offers a cost-effective solution that owners have verified across multiple platforms. It is not a power-adding cam — it is a reliable OE replacement that keeps the van, truck, or SUV on the road.
