Good chop, reliable valvetrain
Everyone always wants the biggest most gnarly cam you can get and don't know about the drop in valvetrain life. The truck Norris gives a nice chop but doesn't kill your valve train like the bigger cams, I've used several of these and it's my go to for any build not going exclusively to the track. I'd still change to the ls6 springs just to add some safety because the stick springs don't love higher rpm
