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 a wide variety of engine combos, and it was spicy enough to make excellent power in both boosted and N/A applications. Things really heated up once it was 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. Using BTR lobes designed in house, this cam had just the right amount of kick that combined both great stability and durability during 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! Upgraded pushrods and springs are needed witht his performance camshaft. Please see our cam kit with those items included if you need a package solution. ***This is a 3-bolt cam (Gen III LS), if you have a single bolt cam (Gen IV LS) you will need to purchase our 3-bolt cam gear conversion kit***
