Why LS Enthusiasts Love the Sloppy Stage 2 Cam

The Sloppy Stage 2 gained popularity because it delivers impressive performance without requiring a massive budget.

Benefits include:

Aggressive Idle Sound

Let’s be honest. Most people buy a cam partly because they want the chop.

The 228/230 duration combined with the 112 LSA produces a noticeable lope that gives your LS-powered vehicle an unmistakable performance sound.

Strong Mid-Range Power

Unlike huge race cams that sacrifice drivability, the Sloppy Stage 2 provides substantial gains throughout the usable RPM range.

Expect improvements in:

• Throttle response
• Mid-range torque
• Acceleration
• Passing power
• Overall engine character

Budget-Friendly Performance

One reason this cam became famous is because it offers excellent value.

Instead of spending premium dollars chasing small gains, builders can install a Sloppy Stage 2 and see significant improvements with supporting upgrades such as:

• Valve springs
• Pushrods
• Long-tube headers
• ECU tuning
• Cold air intake

Does It Need a Tune?

Many product listings claim the cam can be installed without tuning.

Technically, the engine may run.

However, for optimal performance and drivability, tuning is strongly recommended.

A proper tune helps:

• Correct idle behavior
• Optimize air/fuel ratios
• Improve throttle response
• Maximize horsepower gains
• Eliminate drivability issues

Skipping a tune is like buying a turbo and refusing to turn up the boost.

Recommended Supporting Mods

For best results, pair the Sloppy Stage 2 with:

• Upgraded valve springs
• Hardened pushrods
• LS7 lifters
• Timing chain upgrade
• Long-tube headers
• Performance exhaust system
• Professional dyno tune

These supporting modifications help maximize reliability and performance.

Performance Expectations

Power gains vary depending on engine size and supporting modifications.

Typical results include:

• Improved horsepower throughout the powerband
• Stronger mid-range torque
• Faster acceleration
• Enhanced throttle response
• More aggressive exhaust note

Many 5.3L truck builds equipped with a Sloppy Stage 2 cam, headers, intake upgrades, and tuning can achieve impressive gains compared to stock configurations.

Installation Notes

This camshaft uses a 3-bolt design and is intended for LS engines built from 1997 onward.

Before installation:

• Verify piston-to-valve clearance
• Inspect timing components
• Replace worn lifters
• Upgrade valve springs
• Check pushrod length

Proper installation is critical for long-term reliability.

Final Verdict

The E1840P Sloppy Stage 2 Camshaft remains one of the best bang-for-the-buck upgrades available for LS enthusiasts. It delivers the aggressive idle many builders want while providing meaningful power gains across the RPM range.

For street-driven LS swaps, weekend drag racers, and budget-minded performance enthusiasts, the Sloppy Stage 2 continues to prove why it has become one of the most recommended camshaft upgrades in the LS community.

If you’re looking for affordable horsepower and a camshaft that delivers both sound and performance, the Sloppy Stage 2 deserves a spot on your shortlist.
