1. Texas Speed TSP Chopacabra Cam Kit with Springs Seals Pushrods LS Truck Camshaft 4.8 5.3 6.0 6.2 Vortec 1999-2013

When I first came across the Texas Speed TSP Chopacabra Cam Kit, I was immediately intrigued by its promise to bring a serious performance boost to my LS truck engine. Specifically designed for the 4.8, 5.3, 5.7, 6.0, and 6.2 Vortec engines from 1999 to 2013, this camshaft kit targets owners who want to crank up the power without sacrificing everyday drivability. The precision specs of this cam—the 214/222 duration, .550/.550 lift, and a 108 LSA with 106 ICL—highlight that this isn’t just a mild upgrade. It’s engineered to unleash a more aggressive, powerful engine character while maintaining reliability.

What really sets the Chopacabra cam apart for me is the comprehensive nature of the kit. It includes .560 lift Beehive springs, valve seals, and OE replacement pushrods. This means I don’t have to hunt down compatible parts separately, which can often be a hassle and risk compatibility issues. The inclusion of these components shows Texas Speed’s attention to detail and commitment to making installation smoother and more dependable. The Beehive springs are particularly important because they’re designed to handle the increased lift without valve float, ensuring longevity and consistent performance under demanding conditions.

One of the most exciting features is how this cam is optimized for use with LS6 valve springs and a factory torque converter. This is a big deal because it means I don’t need to invest in an aftermarket stall converter, which can add complexity and cost. The factory converter friendliness makes this a practical upgrade, especially for truck owners who want to maintain some level of stock drivability while unlocking more power. The cam operates effectively across a broad RPM range of 1200 to 6500, which means strong performance from idle through high revs—perfect for both daily driving and spirited acceleration.

Under dyno testing, the Chopacabra cam produced an impressive gain of over 65 horsepower and 25 ft-lbs of torque at the crank. These are significant numbers that can dramatically improve towing, hauling, or just the general responsiveness of the engine. For me, this means not only will my truck feel more powerful, but it will also handle tougher tasks with greater ease. The “mean, snarling” sound it promises adds to the overall driving experience by giving the engine a more aggressive exhaust note without being obnoxious. It’s that perfect balance between performance and street-friendly character.

From a drivability standpoint, this cam kit excels. It’s designed to deliver an “amazing chop” in sound and feel while maintaining smooth operation. That’s crucial because I want a camshaft that enhances power but doesn’t make the truck a pain to drive around town or during daily errands. The Chopacabra cam strikes that balance well, making it a solid choice for enthusiasts who want performance without compromise.
