I'd stick with the truck intake because I've seen superchevy.com do a build and found that the truck intake makes more bottom end power which is what you need for the weight of your truck and the ls1 intake makes more power in the top end. There isn't a huge advantage to switching to the lower profile intake. If you're going for aesthetics, I'm sure a true LS enthusiast will know what they're looking at when you pop the hood, regardless of intake.
