224/230 Duration - Aggressive Performance:

The Stage 4 V2 features 224° intake and 230° exhaust duration measured at .050" lift. This aggressive duration provides strong mid-range torque and excellent top-end power while creating that signature lopey idle. The slightly longer exhaust duration helps scavenge exhaust gases efficiently, improving power output throughout the RPM range.

.624/.624 Lift - Maximum Airflow:

The .624" lift on both intake and exhaust valves provides excellent airflow for serious power gains. This aggressive lift requires upgraded valve springs and careful attention to piston-to-valve clearance. The increased lift allows the engine to breathe better at high RPM, resulting in significant horsepower gains.

112° LSA - Truck-Optimized:

The 112° Lobe Separation Angle is optimized for truck applications, providing a good balance of low-end torque, mid-range power, and top-end performance. This LSA creates an aggressive idle while maintaining enough vacuum for power brakes and reasonable fuel economy during cruising.

Stage 4 V2 - What to Expect:

The Stage 4 V2 is BTR's aggressive truck cam designed for enthusiasts seeking serious performance gains:

• Idle: Aggressive lopey idle - very noticeable
• Low-End: Reduced compared to stock, but still usable
• Mid-Range: Strong torque delivery - excellent for acceleration
• Top-End: Pulls hard to 6,200+ RPM
• Sound: Aggressive exhaust note and lopey idle
• Drivability: Streetable with proper supporting mods and tuning

Upgraded Valve Springs REQUIRED:

CRITICAL: This camshaft REQUIRES upgraded valve springs. The stock valve springs are not designed for the aggressive lift and duration of the Stage 4 V2 and will cause valve float, poor performance, and potential engine damage. BTR valve springs or equivalent are required for safe, reliable operation.

Professional Tuning REQUIRED:

CRITICAL: This camshaft requires professional tuning after installation. The aggressive cam profile changes the engine's airflow characteristics significantly, requiring custom fuel and ignition maps for optimal performance, reliability, and drivability. Do not drive aggressively before proper tuning is complete.

Torque Converter Recommendation:

For automatic transmission trucks, an upgraded torque converter with 2,800-3,200 RPM stall speed is highly recommended. The aggressive cam reduces low-end torque, and a higher stall converter helps the engine get into its powerband more quickly. This dramatically improves drivability and performance.
