If you're looking to give your LS engine a serious boost, the TSP Cathedral Heads Stage 2 Camshaft is worth checking out. With specs like 228/232 duration and .600 lift on both sides, this cam isn't just about numbers—it’s about the experience. Designed with both beehive and double valve springs in mind, it strikes a great balance between performance and drivability. I’ve seen it add a solid 5-7 horsepower over the 228R cam, and on the dyno, it’s not uncommon to see gains of 50-55 RWHP when paired with the right bolt-ons.
One thing to keep in mind is that this cam is big enough that if you're running an automatic, you're going to want a stall converter with a minimum of 3200 RPM. It’s all about getting that power to the ground smoothly. And don’t forget, tuning is a must whether you’re driving a manual or automatic. Once you’ve got it dialed in, you’ll find it’s a fantastic daily driver—just the right amount of growl without being obnoxious.
Here’s the lowdown on what you can expect:
Fitment:
Just a heads up: This cam is for competition use only, so it’s not street legal. But if you’re looking to take your ride to the next level at the track, this might just be the upgrade you need.
