Duration (Intake/Exhaust)	214/222
Lift (Intake/Exhaust)	.550/.550
Lobe Separation Angle	108 LSA
Installation Event Marks (ICL)	106 ICL

What We Found

Texas Speed’s TSP CHOPacabra is presented as a truck-first cam that targets 4.8, 5.3, 5.7, and 6.0 LS cathedral-port applications. The listed specs are 214/222 duration with .550/.550 lift and a 108 LSA (106 ICL).

What I like here is that it’s not cam-only: the kit includes .560 lift beehive springs, valve seals, and OE replacement pushrods, which reduces the usual “wait, do I need different parts?” stress.

The description leans into an aggressive, snarling idle and also calls out compatibility with a factory torque converter and LS6-style spring behavior – so it’s aimed at street builds that still want a meaner sound without going to extremes.

Who It’s For

I would shortlist this if you’re building a 6.0 Vortec truck and you want that CHOPacabra sound and mid-range pull, especially with cathedral-port heads and a compatible non-VVT setup.

It’s also a good fit if you’re planning a full top-end refresh anyway, since the included springs, seals, and pushrods help cover the usual cam swap pieces.

The main watch-out is making sure your engine/head setup matches what the kit is aiming at so you don’t run into fitment or parts mismatch.

Duration (Intake/Exhaust)	214/222
Lift (Intake/Exhaust)	.550/.550
Lobe Separation Angle	108 LSA
Cam Pattern	3 Bolt Pattern

What We Found

This Texas Speed & Performance listing bundles the CHOPacabra truck cam with a Gen III/IV install package meant for 6.0 and 6.2 LS-based trucks. The cam specs are listed as 214/222 duration, .550/.550 lift, 108 LSA, and a 3-bolt pattern.

Where this differs from basic cam-only options is the added Delphi LS7 lifters and guide trays (for Gen 3/4 LS applications), plus an LS3-style multi-layer steel head gasket mentioned for many of the listed 6.0/6.2 engines.

If you’re already expecting to refresh lifters and deal with gaskets during the cam swap, that bundle approach reduces separate shopping and makes the install plan easier to keep straight. The CHOPacabra positioning – nasty sound with factory torque converter friendliness – comes through again here.

Who It’s For

I’d point this one at a 6.0 owner who wants to treat the cam install like a maintenance-and-upgrade at the same time. If you’re replacing lifters and refreshing the top-end, having those pieces in the kit helps keep the build coherent.

It’s also a fit if your goal is truck-friendly behavior (including the converter-friendly pitch) rather than chasing a high-RPM race setup. Just confirm the engine’s Gen 3/4 details and the lifter/bolt pattern fitment before ordering.

Duration (Intake/Exhaust)	212/22X
Lift (Intake/Exhaust)	.552/.552
Lobe Separation Angle	107 LSA
Cam Pattern	3 Bolt Pattern

What We Found

BTR’s Truck Norris kit is framed as a truck-torque cam choice for LS trucks where drivability matters. The listed specs are 212/22X duration with .552/.552 lift and a 107 LSA on a 3-bolt pattern.

The package includes the camshaft, BTR SP011 .560 springs, valve seals, and pushrods, along with Delphi lifter support and GM trays per the kit contents. The description emphasizes stronger low- and mid-range torque, plus an idle sound that feels more aggressive without forcing you into constant high-RPM driving.

One detail I’d pay attention to is the compatibility guidance: VVT engines require a VVT delete kit, and 1-bolt cam applications may need a 3-bolt conversion kit. That kind of note matters because it helps prevent the common LS swap confusion around cam retention and crank/valvetrain setups.

Who It’s For

I’d consider this if you’re aiming for better throttle response and mid-range pull in a daily-driven 6.0 LS truck – especially for street or towing where torque delivery is the priority.

It also makes sense if you’re trying to avoid additional converter costs while keeping the install focused on a full refresh approach. The key work for buyers is verifying non-VVT compatibility (or planning the VVT delete) and checking the cam bolt pattern before committing.

Duration (Intake/Exhaust)	212/22X
Lift (Intake/Exhaust)	.552/.552
Lobe Separation Angle	107 LSA
Cam Pattern	3 Bolt Pattern

What We Found

In this listing, BTR Truck Norris emphasizes compatibility across Gen 3 and Gen 4 LS truck engines from 1999-2013. The cam specs shown remain 212/22X duration, .552/.552 lift, 107 LSA, using a 3-bolt pattern.

The description focuses on increasing low- and mid-range torque, improving towing performance, and keeping everyday throttle response in mind. It also promises that the cam is street- and tow-friendly by avoiding the need to live at extreme RPM.

That “more aggressive idle without losing balance” message repeats here, but the big difference is that this listing reads like cam-and-fitment focus rather than a full install kit – so supporting components like springs, lifters, seals, and pushrods may need to come from elsewhere depending on your build.

Who It’s For

This one fits if you’ve already selected the rest of your supporting parts for a 6.0 LS swap. It’s a good match for street-oriented owners who want improved response and a manageable idle, with the truck torque intent also aligning well with towing or mixed-load driving.

Because it’s targeted to Gen 3/4 and a 3-bolt pattern, it can cover many LS truck applications – but I’d still confirm VVT presence and whether your setup needs the conversion approach mentioned in the other listings.

Cam Focus	Strong low-end torque and mid-range power
Lifter Type	Delphi LS7 hydraulic roller lifters
Valve Train Support	OEM-style lifter guide trays
Gasket Material	MLS head gaskets

What We Found

Texas Speed’s Chopacabra Truck Camshaft Install Kit is aimed at a more complete top-end cam swap for 4.8, 5.3, 5.7, and 6.0 LS engines. It includes the Chopacabra cam plus Delphi LS7 lifters, LS lifter guide trays, and LS1 MLS head gaskets.

The description calls out strong low-end torque and mid-range power while keeping valvetrain behavior reliable, and it leans on the included parts to support that hydraulic roller operation (Delphi lifters) and stable motion (guide trays).

The MLS head gasket inclusion also signals that it’s meant for builds where you’re refreshing sealing and moving parts during the upgrade – not just swapping the cam and calling it done.

Who It’s For

I’d put this in front of 6.0 truck builders who plan to replace more than just the cam – specifically lifters, trays, and head gaskets during the swap. It’s also attractive for shops or hobbyists who want fewer separate orders and a more coordinated refresh.

The cam’s low-end/mid-range focus fits street and work-truck driving. Just be sure you verify VVT presence and confirm the head gasket/cam requirements for your exact LS engine setup.

Cam Profile Goal	Low- and mid-range torque improvement
Spring Lift Rating	.560 springs
Lifter Brand	Delphi hydraulic lifters
Compatibility Range	Gen 3/4 LS engines 1999-2013

What We Found

Dynosty’s BTR Truck Norris cam kit takes the bundled approach seriously for LS applications from 4.8 through 6.0 and 6.2. The contents include the cam, BTR SP011 .560 springs, valve seals, pushrods, Delphi lifters, GM trays, and a cam install kit.

The listing references compatibility with 1999-2013 LS-based engines for many GM truck models. It also clearly notes the “extra parts may be required” situations: VVT engines require a VVT removal kit separately, and 1-bolt cam setups need a 3-bolt conversion kit separately.

The advantage here is that the valvetrain pieces are included in a way that supports a cleaner install workflow – especially when you’re targeting improved torque and a more aggressive exhaust note while still aiming for balanced drivability with proper supporting components and tuning.

Who It’s For

I’d shortlist this if you’re trying to build a complete LS 6.0 truck package and want most of the cam-swap moving parts in one order.

It’s geared toward street and tow goals thanks to the truck-oriented torque profile and the included .560 springs and pushrods that help avoid mismatched part issues. Delphi lifters and GM trays are part of the same stability theme.

Before buying, though, confirm VVT status and the cam bolt pattern so you know whether you’ll need the VVT removal and/or conversion parts.

Duration (Intake/Exhaust)	214/222
Lift (Intake/Exhaust)	.550/.550
Lobe Separation Angle	108 LSA
ICL	106 ICL

What We Found

Stage 2 markets a truck-specific cam kit with .560 lift beehive springs, valve seals, and OE replacement 7.400-inch pushrods. The cam specs are listed as 214/222 duration, .550/.550 lift, and a 108 LSA with 106 ICL.

Compatibility is described around LS truck engines with cathedral port configurations across 4.8, 5.3, 6.0, and 6.2. It also states an optimal RPM range of 1200-6500, aiming at towing, street performance, and off-road use.

The listing makes performance claims (+65 HP and +25 lb-ft) based on crank testing, but the provided details don’t name the cam manufacturer or confirm the dyno/testing setup – so those gains are harder to validate from the information shown.

That’s the biggest credibility gap compared with kits that include clearer build/testing context.

Who It’s For

This makes sense for buyers who want a more budget-minded truck cam approach with a usable set of parts included. The stated RPM window fits stop-and-go driving and moderate hauling. It also aligns with LS 6.0 cathedral-port performance characteristics.

Because horsepower gains are called out without full test context, I’d treat those claims as marketing until you can confirm the hardware and test conditions tied to the numbers.

GM Replacement Part	12589016
Plate Upgrade Style	Heavy-duty flat-style plate
Bolt Upgrade	ARP 134-1002 bolt kit
Compatibility	Non-VVT LS 4.8/5.3/6.0/6.2

What We Found

Michigan Motorsports’ thrust retainer plate kit is designed to address a specific reliability concern during an LS cam install on non-VVT engines.

It replaces GM part number 12589016 for non-VVT LS applications and includes a heavy-duty flat-style plate meant to replace the factory countersunk Torx design that can be weaker during disassembly. The goal is to help prevent stripped or seized bolts and improve serviceability the next time you’re in there.

It also includes ARP 134-1002 bolt upgrades to add clamping force and better resistance to loosening under stress. The listing emphasizes use in street, strip, and endurance contexts. This isn’t a cam performance part – its job is to protect an important installation hardware detail for Gen III/IV non-VVT builds.

Who It’s For

I’d consider this for builders who already chose the cam and just want the install to be easier to service later – especially if the vehicle might need repeat cam-related work. It’s relevant for LS 6.0 swaps using non-VVT engines across the listed 4.8, 5.3, 6.0, and 6.2 configurations.

The ARP hardware helps with durability for high-stress driving and repeat maintenance. If you’re on a VVT engine, you’ll need the correct countersunk version since this one is limited to non-VVT.

Duration (Intake/Exhaust)	214/222
Lift (Intake/Exhaust)	.495/.495
Lobe Separation Angle	108 LSA
ICL	106 ICL

What We Found

Texas Speed’s TSP CHOPacabra NSR version takes a “no springs required” approach for LS 4.8, 5.3, 6.0, and 6.2 Vortec engines. The listed specs are 214/222 duration with .495/.495 lift and a 108 LSA (106 ICL).

The big selling point is that it’s intended to work with factory valve springs, plus it’s described as factory torque converter friendly.

If your current springs and pressures are already within the requirements, the NSR approach can cut down both cost and labor since you’re not planning to change spring pressure levels just to make the cam work.

It still aims for a mean, snarling sound with street-friendly behavior, and it calls out best fitment with cathedral-port heads. The tradeoff is that lower .495 lift compared to spring-upgraded versions can cap the performance ceiling.

Who It’s For

I’d shortlist this for 6.0 owners who want CHOPacabra character – sound and torque intent – without replacing valve springs, assuming their factory springs are in good shape and meet the requirements. It also fits budget-focused installs where you want to keep pushrods and springs close to stock.

If you’re keeping the factory torque converter, the NSR setup is aligned with that goal. Still, I’d inspect spring condition and confirm your non-VVT needs before committing.

Duration (Intake/Exhaust)	212/22X
Lift (Intake/Exhaust)	.498/.498
Lobe Separation Angle	107 LSA
NSR Strategy	Reuse factory valve springs and pushrods

What We Found

BTR’s Truck Norris NSR cam is built around the convenience of reusing factory valve springs and pushrods. The listed specs are 212/22X duration, .498/.498 lift, 107 LSA, and a 3-bolt pattern.

The listing explains the trade: it sacrifices only slight power versus the original Truck Norris profile in exchange for spring reuse convenience. It also notes that higher mileage engines should replace springs for best performance.

Like the other Truck Norris options, this one targets strong torque throughout the curve and an idle character that’s described as “roundhouse-kick”-style while still aiming for stock torque converter behavior. It also reiterates that VVT requirements must be checked, with a plan for deletion if the engine uses VVT.

Who It’s For

I’d consider this if you want the Truck Norris feel in a 6.0 build without buying new springs – especially for moderate upgrade projects where your existing valve springs and pushrods can realistically stay in service.

It fits street and tow-focused driving too, since the goal is strong torque with manageable RPM demands. The NSR strategy is also appealing when you’re controlling total project cost. Just verify VVT status and cam bolt pattern compatibility, and check spring condition so you don’t get surprised during install.

What to Look For Before Buying

For a 6.0 LS cam swap, I’d treat compatibility as the real starting point, not just duration and lift. Cathedral-port head fitment, VVT status, cam bolt pattern, and the spring/lifter match often decide whether the truck feels right or starts acting up. Once those are lined up, then you can judge which cam profile matches your torque, idle sound, and converter expectations.

Check Confirm VVT and cam bolt pattern

Start by checking whether your engine uses VVT and whether your setup needs a VVT delete plan. Then confirm the cam bolt pattern requirement – especially whether a conversion is needed for 1-bolt cam applications. Getting this wrong creates avoidable delays and extra parts before you even touch the valvetrain.

Value Compare kit completeness

A lot of cam confusion comes from “cam-only” listings. Some kits include springs, lifters, seals, and pushrods – others don’t. I’d look for a bundle that matches the exact valvetrain needs implied by the cam’s lift and profile, so you don’t end up sourcing mismatched parts mid-install.

Rating Use rating signals and naming consistency

When ratings are missing, I lean harder on clear compatibility notes, part numbers, and spec transparency. If a listing makes big horsepower claims but doesn’t give testing context or consistent hardware details, I’d stay cautious. The safer route is picking parts where the fitment and supporting components are spelled out.

Verify Match heads and spring strategy

Verify cathedral-port versus other head types before ordering. Then decide whether you’re going NSR (reusing factory springs) or spring-upgraded. For NSR, spring condition matters. For spring-required cams, make sure the spring lift and package specs match the cam profile, and confirm converter-friendly expectations with your tune and transmission setup.

Frequently Asked Questions

What cam specs matter most for a 6.0 LS truck build?

Duration, lift, and lobe separation angle are the big three because they shape idle character and the torque curve. For truck-focused grinds, the 107-108 LSA range shown across these options is often what helps keep street behavior usable. But the real difference comes from matching springs and lifter strategy to the cam’s lift, plus making sure the cam fits your heads and VVT setup.

Should a 6.0 LS run an NSR cam or a spring-required cam?

NSR cams can be attractive because they’re built to reuse factory valve springs, which can lower cost and simplify parts planning. Spring-required cams often unlock more lift and a wider performance ceiling, but they also mean you need the correct spring package and matching valvetrain parts. For NSR builds, the condition of the factory springs matters a lot – especially on higher mileage trucks.

Do these cams work with a stock torque converter?

Some of the listings explicitly aim for stock torque converter-friendly behavior, but “works with” depends on idle vacuum/overlap, your tune, and your transmission settings. Truck Norris and CHOPacabra descriptions mention converter friendliness, so they’re at least designed with that in mind – but stall speed and driving conditions can still change how the truck feels.

What additional parts are commonly needed for an LS cam swap?

Most installs revolve around valve seals, correctly matched springs (or confirming your factory springs can be reused), and pushrods. Many cam swaps also replace hydraulic lifters and lifter guide trays. Depending on the build, gaskets, and sometimes thrust hardware or conversion parts (for VVT/bolt pattern) can also be part of the job. Always verify Gen III/IV differences before ordering.

How important is tuning after installing a cam?

Tuning is usually a must after a cam change because idle quality, drivability, and air-fuel control can shift when the cam timing and overlap change. Cam timing and fuel/transmission behavior often need adjustment. Without tuning, the truck can feel rough or less responsive than the parts’ intent.

🎯 Final Verdict

BTR Truck Norris in a kit format comes out as the best choice for a 6.0 LS truck build: the .552/.552 lift on a 107 LSA is aimed at strong low- and mid-range torque, and the kit approach is designed to reduce parts mismatch by including .560 springs, seals, and pushrods. Texas Speed CHOPacabra is a strong alternative when cathedral-port fitment and a CHOPacabra-style truck sound are the priority – especially if you’re going with the more complete install bundles. Either way, confirm VVT and bolt pattern requirements before you check out.
