Chrysler / Dodge / Jeep 6.1L HEMI V8 (2005–2010, Non-VVT)
🔥 Purpose & Identity
The Red Line Vortex 218/224 Phantom is for those who want to keep it low-key but lethal.
This grind was designed to transform the 6.1L HEMI into a sharper, more responsive powerplant while keeping street manners fully intact.It idles with a subtle, rhythmic lope — not obnoxious, but unmistakably performance-bred. On the road, it hits with smooth low-end torque and a hard midrange pull that feels factory-refined until you bury the throttle — then the Phantom shows its true face.
If you want a cam that moves in silence but hits with authority, this is it.

⚖️ LSA Power & Idle Characteristics
110° LSA:
Sharper throttle, noticeable chop, and a harder torque hit — great for lighter cars and manual setups.
112° LSA (Standard):
Balanced tone and powerband — crisp response with enough idle character to sound alive.
114° LSA:
Smoothest idle, best vacuum, and wide torque curve for heavy or automatic-equipped cars.
🏁 Performance Behavior
The 218/224 Phantom focuses on driveable aggression — torque right where you use it, fast rev pickup, and a confident tone that doesn’t compromise comfort.
In a tuned 6.1L with headers and intake, expect 25–40 rear-wheel horsepower gains with a noticeable bump in torque across the lower and middle range.
The tighter 110° version hits like a hammer; the 114° variant delivers smoother, factory-like behavior with hidden power underfoot.
Perfect for street cars that want a sleeper edge — quiet in the background, lethal on command.
