*NEW* BTR "Truck Norris" Gen III & IV Truck Cam
Specs:
From BTR:
"The Truck Norris will deliver a roundhouse kick in the pants to your 1999-2013 Silverado or Sierra. Developed from hundreds of hours of in house cam lobe design and dyno testing, this camshaft has more power and torque everywhere in the curve compared to our legendary V2 truck cams. "
This camshaft makes exceptional power in the Gen III & IV GM Truck platforms, especially for a low lift grind. In addition to power gains across the board this cam has an aggressive sounding idle with plenty of "Chop", while still remaining compatible with the OEM torque converter in BTR's testing.

Note: NOT COMPATIBLE with 2014+ Gen V LT Truck applications (L83/L86)
Note: Requires DOD and/or VVT Delete in 2007-2013 application where applicable
Note: 3-Bolt Style Camshaft
