Specs That Matter

Duration @ .050: 212/23X
This high-duration profile gives your HEMI more valve time at high RPM, translating to stronger top-end power without sacrificing street manners. It’s designed to unleash your engine’s full potential while keeping it daily-drivable.

Lift: .587/.586
With nearly .59 inches of lift, the Truck Norris cam opens the valves farther than stock, allowing more air and fuel into the engine. The result? A thicker midrange, more torque at cruising RPMs, and a big smile every time you bury the throttle.

LSA (Lobe Separation Angle): 109.5°
The cam’s 109.5° LSA strikes the perfect balance between aggressive power and smooth idle. You get an “angry-but-streetable” lope, excellent throttle response, and no harsh idle chatter — even on a daily driver.

Operating Range: 1,500–7,000 RPM
From towing on the highway to late-night drag strip runs, the Truck Norris cam delivers a broad, usable powerband. It gives you the low-end grunt and the high-RPM pull you want without any dead spots.

Chop Scale: 5/7
This cam is noticeable without being overbearing. On the chop scale, 5/7 means your neighbors will hear it, but your truck is still completely streetable. It’s the sweet spot for those who want attitude with control.

Dyno-Proven Gains: +69 HP / +18 lb-ft torque at 6,000 RPM
BTR didn’t just test this cam on paper. Real-world dyno pulls prove that the Truck Norris HEMI Camshaft delivers serious performance gains right where you can feel them — midrange to high RPM.

Factory Converter Friendly
No need to spend extra on a high-stall converter unless you want to. This cam plays nicely with your stock converter, keeping your daily driver functional while delivering a meaner attitude under full throttle.
