• Gen III LS engines
• Gen IV LS engines

Compatible applications include:

• LS1
• LS2
• LS3
• 5.7L LS
• 6.0L LS
• 6.2L LS

Popular fitment includes:

• Chevrolet Corvette
• Chevrolet Camaro

Basically the exact vehicles most likely to end up with loud exhaust systems and suspiciously sticky rear tires.

BTR Red Hot Camshaft BTR-REDHOT (Specs: 221/24X .619/.617 113 LSA) BTR is proud to introduce our newest camshaft offering for 5.7, 6.0, and 6.2 LS engines. Affectionately dubbed The Red Hot Cam, we have put this camshaft in all kinds of engine combos, and it was once spicy enough to make excellent power in both boosted and N/A applications.

BTR Red Hot Cam Specs

The Red Hot camshaft specs include:

$221/24X.619/.617113LSA$

This setup delivers:

• Strong midrange power
• Excellent top-end airflow
• Improved throttle response
• Aggressive but manageable idle quality

The wider:

• 113 LSA

Helps maintain:

• Better drivability
• Improved vacuum
• Smoother operation

Compared to extremely tight LSA chop-monster cams.

Because some LS owners still want functioning brakes and normal conversations occasionally.

Things in reality heated up once it was once installed and running on the engine dyno. It showed excellent power gains over our existing Stage 2 PDS and LS3 Centrifugal cam profiles even with less intake duration.

Excellent Naturally Aspirated Performance

The BTR Red Hot Camshaft is optimized for:

• Naturally aspirated LS builds
• Street performance setups
• Aggressive daily drivers
• Roll racing applications

Helping improve:

• Horsepower
• Torque
• Midrange acceleration
• Upper-RPM pull

Especially when paired with:

• Long tube headers
• Ported heads
• Intake upgrades
• Free-flowing exhaust systems

Because naturally aspirated LS engines absolutely thrive on airflow.

The usage of BTR lobes designed in house, this cam had just the correct amount of kick that combined both great stability and durability all over Spintron testing. Scoring a 1.5m SHU (Think Carolina Reaper and Pepper Spray) on the Scoville Scale, this cam is sure to add some heat to your build!

Aggressive Idle Without Total Madness

Yes:
The Red Hot cam still chops.

You’ll get:

• Noticeable lope
• Deep exhaust tone
• Aggressive startup sound
• Cammed LS attitude

But unlike giant race-oriented camshafts:

• It remains street-friendly
• Easier to tune
• More vacuum-stable
• Better for daily use

Basically enough aggression to sound cool without making every drive-thru interaction feel mechanically stressful.

Upgraded pushrods and springs are needed witht his performance camshaft. Please see our cam kit with those items included if you wish to have a package solution.

Excellent Midrange & Top-End Pull

One major advantage of the Red Hot profile is:

• Balanced power delivery

Helping create:

• Strong acceleration
• Smooth RPM transition
• Hard upper-RPM charge
• Better overall responsiveness

Perfect for:

• Street cars
• Highway pulls
• Weekend track builds
• Roll racing setups

Because LS engines pulling hard past 6,000 RPM remains one of the best sounds in automotive culture.

***This can be a 3-bolt cam (Gen III LS), if in case you have a single bolt cam (Gen IV LS) it is very important purchase our 3-bolt cam gear conversion kit***

• C5 Corvettes
• C6 Corvettes
• Camaros
• GTOs
• LS-swapped builds

Helping modernize:

• Airflow
• Valvetrain behavior
• Overall engine personality

Because factory LS camshafts were designed by engineers…
…and enthusiasts immediately decided that was too reasonable.

Brian Tooley Racing Quality

And because LS culture somehow still feels deeply patriotic at idle.

Final Thoughts

The BTR Red Hot Camshaft is an excellent naturally aspirated LS camshaft for enthusiasts wanting strong horsepower gains, aggressive sound, and excellent street manners.

With balanced cam specs, strong midrange power, top-end performance, and proven BTR engineering, the Red Hot cam remains one of the best all-around LS street-performance upgrades available.

Because eventually every LS owner decides stock idle quality sounds far too emotionally stable.
