Hi so recently I added an intake, throttle body, new plugs, bully dog gt and removed my muffler. It seams I have gained a lot of power. And of course I'm hooked and want more hp. From what I have read a cam swap is the next thing I should look at. So saying this how would I go about finding what cam to purchase what else do I need? Springs lifters ect. I want to do it right the first time and change what I need to get the most hp out of it. Thanks in advance for the replys. I have a fair amount of knowledge of engines but not sure on some of the more technical things so take it easy on me.

 

Sorry to miss it is a 2008 gmc Sierra 2500hd 6l
