From Texas Speed:
"Ready to bring the chop without tearing into the valvetrain? The new Chopacabra NSR (No Springs Required) Camshaft delivers the unmistakable idle and attitude you expect from the Chopacabra lineup — without needing an upgraded valve spring kit. If you're looking for aggressive sound and a stealthy install, this cam was built for your 6.0L or 6.2L LS build. The Chopacabra NSR gives you the sound of a full cammed LS build — with none of the extra work. If you're looking for the easiest way to add lope to your LS3-headed 6.0 or 6.2, this is it."
