HEMI owners, get ready to unleash some serious power! This Brian Tooley Racing Truck Norris camshaft is like a roundhouse kick to your engine's performance - hence the awesome 'Truck Norris' name. Specifically designed for 2009 and up Gen III 5.7L HEMI engines with VVT, this thing is no joke. We're talking about specs that'll make your heart race: 212/23X duration, .587/.586 lift, 109.5 LSA. On the dyno, this bad boy showed gains of 71 HP and 62 lb/ft at 6000 RPM - and it just keeps pulling strong all the way to 7000 RPM! You'll need to pair it with the right valve springs (SK017, SK017/TS, or SP021-16), do the MDS conversion, and definitely get a VVT limiter. The coolest part? You get this aggressive rumble that sounds mean without sacrificing daily drivability - it actually works well with factory converters. Imagine approaching 490 HP at the crank with an extra 1500 RPM of usable power band. Whether you're in a Ram truck, Charger, or Challenger, this camshaft transforms your ride from ordinary to extraordinary. Just like Chuck Norris, this cam doesn't mess around!
