- Compatibility: Make sure the kit is designed specifically for the 5.3 Vortec and your truck’s model year.
- Included Hardware: A good cam kit should include lifters, springs, and retainers to avoid mismatched parts.
- Installation Complexity: Some kits require professional installation. I recommend having a mechanic if you’re not experienced.
- Tuning Needs: After installation, tuning the ECU is often necessary to maximize the cam’s benefits. I used a custom tune to optimize performance.
