The newest cam from BTR's LS lineup. Designed for 5.7L, 6.0L, and 6.2L Gen III and Gen IV LS engines. Extensively tested on the engine dyno in both naturally aspirated and boosted combinations — strong across the board, with an aggressive idle you'll know is there.

What the Red Hot cam is
BTR built this cam to outperform their existing Stage 2 PDS and LS3 Centrifugal profiles on the dyno — and it did, with less intake duration. It uses BTR's in-house lobe designs, which means it's not a generic grind. The 113 LSA positions it as an aggressive street cam: a choppy idle at cruise, strong torque through the mid-range, and it keeps pulling through the top end when paired with the right valvetrain.
BTR validated it on their Spintron before release. That matters for cam longevity in a flat-tappet world — and this being a roller cam, it's the same process they apply to everything in their performance lineup.

What it needs to run correctly
The Red Hot cam uses 0.619" intake lift. Standard LS valve springs — factory or mild upgrades — won't handle that reliably at sustained RPM. A dual spring kit rated to 0.650" or better is the right call. BTR's own Platinum LS Dual Spring Kit with titanium retainers is purpose-matched for this cam. Talk to the team at IMS and they'll spec the full valvetrain for your combination.
Engine tuning is required after install. This is not a plug-and-play cam — it changes the VE table enough that stock tune fuelling will be wrong. IMS can handle remote ECU tuning via HP Tuners, EcuTek, and Haltech platforms depending on your setup.
