If you’re looking to crank up the power on your 5.7 or 6.0L engine, the Texas Speed Heads and Cam Package is where it’s at. This setup is all about unleashing some serious horsepower—think in the ballpark of 525 to 550 HP, depending on what else you’ve got going on with your exhaust and intake. It’s not just about the numbers, though; it’s about the growl that comes with it. The lopey camshaft gives your ride that aggressive sound that makes heads turn.

Now, let’s get into what makes this kit tick. You’re getting the TSP Stage 4 Tsunami Camshaft, which is designed for maximum power and has a pretty bold lope to it. With specs like 235/240 duration and lift of .629/.615, it’s built to perform at high RPMs while giving you that sweet aggressive idle. It’s perfect if you’re looking to really make your engine stand out.

But don’t stop there; the PRC As-Cast 225cc Cathedral Heads are a game changer too. These heads are all about flow and combustion efficiency, allowing your engine to really breathe. With a 225cc intake runner volume and a 62cc combustion chamber, they’re made to handle extreme horsepower. Plus, they come with premium valves and valve seats for durability, and they’re paired with a TSP 660 Spring Kit and titanium retainers for top-notch valve control when you’re pushing the limits.

When it comes to installation, you’ll need a few extra components to get everything in place, like the Heads & Camshaft Bolt Gasket Kit. And if you’re running an automatic transmission, consider upgrading to a 3200+ stall torque converter to really make the most of this setup. For those rocking a manual, you’ll want to look at 3.73 or 4.10 rear-end gears to harness all that newfound power.
