Texas Speed & Performance Torquer V4 Stage 3 Camshaft for Cadillac, Chevrolet, GMC 1997-2014
$389.99

TSP Cathedral Heads Stage 3 Camshaft

If you're looking to kick your LS engine up a notch, the TSP Stage 3 Camshaft is where it’s at. This baby has a more aggressive intake lobe profile that really wakes up your engine. We're talking specs of 231/234 duration and lift figures of .629" and .615"—definitely not for the faint of heart.

Now, before you dive in, make sure you’ve got a solid double valve spring kit. We’re big fans of the PAC .660” springs for this setup—they handle the extra lift without breaking a sweat. With the tweaks made to the cam design, you'll notice peak power comes in earlier than the previous Torquer V2, which is a sweet bonus if you want that low-end grunt.

For those rolling with an automatic, a 3200 RPM stall converter is a must. Trust me, it makes a world of difference when you're trying to harness all that power. And whether you’re running a manual or an automatic, don’t skip out on tuning—it's essential to get everything dialed in just right.
