Stage 4 - 224/24X, .587/.586, 112.5 LSA
This ‘Stage 4’ grind provides an additional 1900 RPM of usable operating range while maintaining drivability when paired with an aftermarket Torque Converter. On the BTR Dyno, we observed gains starting at 3800 RPM, with a peak gain of 83 HP and 72 lb/ft at 6000 RPM. The ‘Stage 4’ continues to pull strong past 7100 RPM!

NOTE: The use of a BTR aftermarket spring kit is required due to high valve lift and increased rpm potential in combination with the heavy OEM valves. We also recommend the use of hardened pushrods in power adder applications.

NOTE: To take advantage of this grind, it is imperative to utilize VVT control and engine tuning. A proper calibration with attention to detail in this respect will make this camshaft SHINE! *See Cam Card for recommended Holley VVT Target Table.*
