Texas Speed TSP Chopacabra Truck Camshaft LS 4.8 5.3 6.0…

This cam is marketed as a “nasty little beast,” and it lives up to the name (at least in terms of sound). The Chopacabra is designed for a noticeable performance bump without breaking the bank. Its lower lift profile means it’s kinder on your valvetrain components, making it a decent choice for daily drivers. Texas Speed offers several kit options, ranging from just the camshaft to complete kits with springs, seals, and even pushrods – a definite convenience.

• 214/222 .550″/.550″ 108LSA
• Designed to work with LS6 valve springs and factory torque converter.
• Multiple kit options available for varying needs and budgets.
• Proprietary lobe profiles for efficient performance.

Pros:
– Affordable
– Relatively easy installation (depending on your kit choice)
– Noticeable performance gains
– Good option for daily drivers

Cons:
– May require additional components (DOD/AFM delete, VVT delete, 3-bolt conversion kit).
– The aggressive sound might not appeal to everyone.
– Potential supply chain issues (mentioned by Texas Speed).

User Feedback Summary: Many users report noticeable improvements in throttle response and horsepower. Some note the aggressive cam sound. A few mention difficulties with installation related to needing additional components.

This camshaft is specifically designed for certain Chevy/GMC 4.8L and 5.3L Vortec engines. The 3-bolt design and compatibility with specific VINs make it important to verify your engine’s specifics before ordering. The lack of AFM/VVT makes for a cleaner installation in compatible engines.

Stage 3 Truck Camshaft Kit Compatible with 1999-2013…

This Stage 3 kit offers a significant performance jump but comes with a higher price tag. It includes the camshaft, LS6 springs, seals, and pushrods – a comprehensive package designed for improved power without excessive compromises on low-end torque. It’s aimed at heavier trucks and SUVs, suggesting good suitability for the 7.4L.

• Includes camshaft, LS6 springs, seals, and pushrods
• Designed for increased power in heavier vehicles
• High-strength stainless steel construction

Pros:
– Significant performance gains
– Complete kit for a streamlined installation
– Durable construction

User Feedback Summary: Users report substantial power gains but note the increased idle noise and potential fuel economy decrease.

Practical Buying Advice

The best camshaft for your 7.4 Vortec depends heavily on your goals. For a simple, reliable upgrade with minimal fuss, a factory replacement is great. If you want a noticeable power increase at a reasonable price, the Texas Speed Chopacabra is a solid contender (but be aware of potential additional parts needed). For maximum performance, the Stage 3 kit is worth considering – but remember, it’ll cost you more and likely affect fuel economy. Always check for engine-specific compatibility before you buy.
