🔥 Performance Benefits:
Increased Lift for Better Flow: With .496" lift on both intake and exhaust, the 270 Demon camshaft maximizes air intake and exhaust flow, leading to a noticeable increase in mid-range torque and top-end horsepower. This cam is ideal for builds pushing higher RPMs while retaining drivability.
Aggressive Exhaust Duration (290°): The 290° exhaust duration provides an aggressive exhaust valve opening and closing pattern, allowing better scavenging and a noticeable increase in exhaust flow, which enhances overall engine performance, especially at high RPMs.
Intake Duration (274°): The 274° intake duration offers a wide powerband, improving both low-end torque and top-end power. This combination of intake and exhaust timing ensures smooth acceleration and strong throttle response across the entire RPM range.
111° LSA for a Balanced Powerband: The 111° LSA provides an ideal compromise between aggressive power and streetability. It offers a slightly smoother idle while still delivering that “race cam” lope and outstanding performance at higher RPMs.
Precision Valve Events: The cam’s precise valve timing ensures excellent control of intake and exhaust flow, contributing to better combustion efficiency and more power per cylinder.
 
🧰 Installation Notes:
Spring Requirements: Ensure your valve springs are capable of handling the .496" lift. Performance valve springs with higher pressure are recommended to ensure proper valve control and prevent valve float at higher RPMs.
Cam Timing and Tuning: To optimize performance, it’s recommended to degree the cam during installation then dyno tune. This ensures the cam is properly aligned with your engine and can tune to maximum power and efficiency.
Exhaust System Compatibility: A high-flow exhaust system is crucial to fully realize the cam's potential. Pairing the cam with high-flow headers and a custom exhaust setup will reduce backpressure and maximize exhaust flow, boosting horsepower even further.
Lubrication: Use ZDDP-rich break-in oil during the initial startup to protect the cam and lifters during the break-in process.
 
✅ Fitment:
Engine Compatibility: Suitable for performance builds for  Harley Davidson Evolution, Milwakee M8 & Twin Cam V-Twin engines
