The LS1 is a very camshaft-friendly engines GM ever built. The factory cam is conservative, which means a well-chosen aftermarket grind can wake up the whole engine with more lift, more duration, and a wider lobe separation tuned for your goals. The right cam transforms throttle response, midrange torque, and top-end pull, and it gives you that lopey idle so many LS1 owners are chasing.
The wrong cam, though, leaves you with a rough idle, lost vacuum, and no real power to show for it. We sorted through the most popular LS1 cams sold today and ranked seven that consistently deliver on the dyno and on the street. Whether you want a stealthy daily driver upgrade or an aggressive cam for a heads and headers build, there is a grind here that fits.

1. BTR Stage 2 Truck/LS1 Camshaft: Best Overall
BTR has built its reputation on cams that make real, repeatable power, and this Stage 2 grind is the one we recommend to most LS1 owners. It hits a sweet spot that bigger cams miss: a fat torque curve down low, a strong midrange surge, and enough top end to make the car feel genuinely fast. On a typical LS1 with a tune and a set of headers, this cam wakes the engine up everywhere in the rev range rather than just at the top.
The honest weakness is that to run it safely you should plan on a matched valve spring upgrade, since the factory springs are not happy at higher lift over time. Budget for that and the swap is straightforward. The idle has a noticeable lope, which most owners love, but it does soften manifold vacuum a little, so check your power brake setup. For the money and the results, this is the cam we keep coming back to.
- Designed by Brian Tooley Racing specifically for LS street builds
- Strong torque band from low rpm through the midrange
- Works well with stock or upgraded valve springs depending on lift package
Pros: Excellent balance of power, drivability, and idle character; Proven dyno results on countless LS1 builds; Pulls hard without needing exotic supporting mods
Cons: More aggressive grinds require a spring upgrade to be safe; Lopey idle may reduce vacuum for power brakes on some setups
2. Texas Speed & Performance TSP MS3 Camshaft: Best for Street Builds
Texas Speed is a name LS owners trust, and the MS3 is one of their most requested street and strip grinds. On an LS1 with ported cathedral port heads and long tube headers, this cam really shines in the upper midrange and on top, where it keeps pulling well past where a milder cam signs off. It is the kind of grind that makes a Camaro or GTO feel like a different car at the strip.
The trade-off is that the MS3 wants supporting mods to give its best. Drop it into a stock-headed LS1 and you will leave power on the table, and the idle gets choppier than a casual daily driver might want. If you are committed to a real heads, cam, and headers package, though, this grind rewards you with serious numbers and a great attitude. It is our top pick for owners building toward a fast street car.
- Popular TSP MS3 grind tuned for aggressive street and strip use
- Strong upper midrange and top-end power on a built LS1
- Pairs cleanly with ported heads and long tube headers
Pros: Big power potential for cathedral port LS1 heads; Aggressive but still streetable with the right converter; Backed by a brand known for LS dyno development
Cons: Best results need ported heads, headers, and a good tune; Idle and vacuum drop make it less ideal for a bone-stock car
3. COMP Cams XFI RPM 54-414-11 Camshaft: Best Brand Name
COMP Cams is one of the oldest and most recognized names in the camshaft world, and the XFI RPM series brings their proven lobe technology to the LS platform. This grind is built for the LS1 owner who wants a clear improvement in torque and throttle response without turning the car into a temperamental project. The wider lobe separation keeps the idle reasonable and preserves enough vacuum for accessories, which matters on a daily driver.
The honest limitation is that this cam is tuned more for street manners than for chasing peak numbers, so it will not pull as hard on top as the more aggressive grinds on this list. If your goal is the biggest dyno figure possible, look higher up. But if you want a refined, well-mannered upgrade from a brand you can trust, the XFI RPM is hard to beat and it stays pleasant to live with every day.
- COMP Cams XFI lobe design for improved cylinder filling
- Wide lobe separation keeps idle and vacuum more civil
- Strong low and midrange torque for street driving
Pros: Smoother idle and better vacuum than aggressive race grinds; Trusted COMP Cams quality and consistency; Great choice for a daily driven LS1 that still wants more punch
Cons: Top-end power is milder than the bigger street and strip cams; Less of the heavy lope some owners specifically want
4. Trick Flow TrackMax LS Camshaft: Best Street Manners
Trick Flow built the TrackMax line for enthusiasts who want a noticeable bump in performance while keeping the car easy to drive every day. The single-pattern grind, with matched intake and exhaust duration, delivers a smooth and broad torque curve that makes the LS1 feel responsive and strong across the rev range. It is the kind of cam that makes you enjoy the car more in normal driving, not just at wide-open throttle.
Where it falls short is at the extremes. If you are after a heavy, aggressive idle or the absolute highest peak numbers, this is not that cam, and the larger grinds on this list will out-pull it on top. But for a balanced upgrade that respects drivability and works well with modest supporting mods, the TrackMax is a smart, low-hassle choice that punches above its reputation.
- Trick Flow TrackMax profile balanced for street performance
- Even intake and exhaust duration for smooth power delivery
- Designed to work with stock or mild supporting modifications
Pros: Broad, usable torque curve that feels great on the street; Retains decent idle quality and drivability; Good fit for owners who want power without drama
Cons: Not the cam for someone chasing the most aggressive lope; Peak power trails the larger heads-and-cam grinds
5. COMP Cams Thumpr 54-600-11 Camshaft: Best Lopey Idle
Some LS1 owners care about the sound as much as the numbers, and the COMP Cams Thumpr was designed specifically to deliver that aggressive, rumbling idle that turns heads at every stoplight. The tight lobe separation angle is what creates the signature choppy character, and the cam still adds a real punch of midrange torque so it is not all show. If you want your LS1 to announce itself, this grind does exactly that.
The catch is that the same tight lobe separation that makes it sound mean also cuts manifold vacuum, which can complicate power brakes and idle tuning, especially on an automatic without a looser converter. It is also a sound-first grind rather than the outright power leader here. But for the owner whose number-one priority is that unmistakable Thumpr idle with a genuine performance bump attached, this cam absolutely earns its spot.
- COMP Cams Thumpr profile engineered for an aggressive idle sound
- Tight lobe separation creates the signature rough idle
- Adds midrange torque along with the attitude
Pros: Delivers the loud, choppy idle many owners want; Noticeable midrange power gain over stock; Distinctive sound sets the car apart
Cons: Tight lobe separation reduces vacuum and can affect drivability; Sound-focused grind is not the top power option on this list
6. Lunati Voodoo LS Hydraulic Roller Camshaft: Best Value Performance
Lunati has a long history in the performance camshaft world, and the Voodoo LS grind brings their dual-pattern philosophy to the LS1. The extra exhaust duration is well suited to the LS cylinder head design, and the result is a cam that builds strong, usable midrange torque with an idle that has just enough lope to let everyone know something has changed under the hood. It is a well-rounded grind that delivers a lot of character and grunt.
The honest weakness is that, like most cams in this lift range, it really should be paired with an upgraded valve spring to ensure long-term reliability, so factor that into your plan. Lunati also does not have quite the LS-specific name recognition of some rivals, which makes some buyers hesitate. That is unfounded, though, because the Voodoo performs, and for owners who want strong results without overbuilding, it represents excellent value for the effort.
- Lunati Voodoo grind tuned for strong street and strip torque
- Dual-pattern design favors LS exhaust flow
- Aggressive enough for a fun idle while staying streetable
Pros: Strong midrange torque for the kind of effort it asks; Good idle character without going overboard; Solid quality from a respected cam maker
Cons: Benefits from a valve spring upgrade for reliability; Less brand recognition than COMP or BTR for some buyers
7. Summit Racing Stage 2 LS Camshaft: Best Starter Cam
If this is your first cam swap and you do not want to bite off more than your build can handle, the Summit Racing Stage 2 LS cam is a sensible place to start. The specs are moderate by design, which means it plays nicely with a mostly stock LS1 and a basic tune, and it still delivers a clear improvement in throttle response and midrange torque over the sleepy factory grind. It is an easy way to get into the LS cam game without a long parts list.
The flip side of that approachability is that the Summit Stage 2 is conservative. It will not give you the heavy lope or the big top-end charge that the more aggressive cams on this list provide, and a more experienced builder may quickly want more. But as a confidence-building first step that reliably improves the car without demanding a full supporting package, it is a smart and honest choice.
- Summit Racing Stage 2 grind aimed at first-time cam swappers
- Moderate specs designed to work with mostly stock supporting mods
- Improves throttle response and midrange over the factory cam
Pros: Approachable specs that are forgiving on a stock-ish LS1; Noticeable improvement over the factory camshaft; Backed by Summit Racing support and availability
Cons: Conservative grind leaves power on the table versus bigger cams; Less dramatic idle and top-end than the aggressive options
Frequently Asked Questions
Do I need a tune after installing a cam on my LS1?
Yes, you should always plan on a tune after a cam swap. A new cam changes how the engine breathes, so the factory fuel and spark tables are no longer optimal. Without a tune you can end up with poor idle, hesitation, and lost power, and in some cases a check engine light from idle and fueling that the stock calibration cannot manage. A proper tune lets the cam make the power it is capable of and keeps the engine running smoothly, so budget for it as part of the install rather than an afterthought.
Do I need new valve springs when I install an LS1 cam?
For most of the cams on this list, yes. The factory LS1 valve springs are fine for the stock cam, but higher lift grinds put more stress on them and can lead to valve float or spring failure over time. Upgrading to a quality aftermarket dual or beehive spring rated for your cam’s lift is cheap insurance and is strongly recommended whenever you move to a more aggressive profile. Milder cams near stock lift may survive on factory springs, but matching springs to your cam is the safe path for any performance build.
What does lobe separation angle mean for my LS1 cam?
Lobe separation angle, or LSA, is the distance in degrees between the peak of the intake lobe and the peak of the exhaust lobe. A tighter LSA, around 107 to 110 degrees, gives that aggressive, choppy idle and tends to build strong midrange torque, but it lowers vacuum and can complicate power brakes. A wider LSA, around 113 to 116 degrees, produces a smoother idle and better vacuum with a broader power curve. Choosing the right LSA is really about balancing the sound and behavior you want against the drivability you need.
Will a bigger cam alone make my LS1 fast?
A cam by itself will help, but it gives its best when matched with supporting modifications. Aggressive grinds are designed to move more air, so they pay off most when the engine can actually flow that air through ported heads, long tube headers, and a good intake. Dropping a large cam into an otherwise stock LS1 can even feel disappointing because the rest of the engine becomes the bottleneck. For the strongest results, think in terms of a complete package rather than a single part, and match your cam choice to the rest of your build.
Can I install an LS1 cam myself at home?
Many enthusiasts do a cam swap in their own garage, and the LS1 makes it more approachable than many engines because the cam can be changed without pulling the heads in most cases. That said, it is a real job that involves the timing components, lifters, and careful attention to break-in if you are using a flat tappet style, though LS cams are hydraulic roller. You need basic tools, patience, and a good guide. If you are not comfortable with engine internals, having a shop handle the install and tune is money well spent to avoid costly mistakes.
Our Verdict
For the widest mix of power, drivability, and that satisfying LS1 idle, the BTR Stage 2 camshaft is our top pick because it delivers strong gains everywhere in the rev range without demanding an exotic parts list. If you are building a more serious street and strip car with ported heads and headers, the Texas Speed TSP MS3 is the runner up and will reward that effort with bigger top-end numbers. Whichever you choose, match the cam to your goals and supporting mods, plan for a tune and the right valve springs, and your LS1 will feel like a brand new engine.
