Best bet is to call a cam company, tell them what you want out of it, and have them recommend a grind.

There is truth to the above statement that there is no perfect cam for your truck. It ultimately rests on what your goals are. If you want to retain stock like driveability there are cams available or cam specs that will work quite well for a custom grind that will allow you to retain your stock stall converter, drive like stock, and still pick up some decent power at the wheels. If your not opposed to running a looser converter the sky is the limit. You will need valve springs, pushrods, camshaft, its also worth upgrading the oil pump and timing chain while your in there as the factory units are not the greatest.

Comp cams and trick flow have great options when it comes to the LSX. But depending on the power numbers your looking for will greatly help cam selection. If your just wanting a mild cam that's better than stock and give you a little hp boost you need to choose one with a lower rpm range and lower lift. If you go this way you don't have to upgrade your valve train and get a stall, but even if your going for this it's a good idea to replace the springs especially if your motor has over 100k miles. If your wanting more hp you can't just buy a big cam and exspect it to perform it will fall on its face first time you hit the throttle. But if your wanting more hp I would recommend either a comp cam extreme energy with rpm range 1,800-6,800 222*int/224*exh duration @ .050" and lift .566"int/.568"exh or same brand with an rpm range from 2,000-7,000 224*int/230*exh. Lift.581"int/.588"exh both of these cams will put you back about $400.00 and trick flow track max cams are nice but they are built to match trick flow heads. And I would get some springs that have a spring rate of at least 379lbs and I would get a 2,500 to 3,000 stall and some roller rockers would help out too. If you go this route you will need at least $1,500 but for the money you are going to have a nice little motor. I have seen similar builds with a few more mods headers, msd coils and plug wires roller rockers, and a holley hi ram modular intake manifold with a 102mm throttle body making over 350 rwhp. But even if you went with a small cam and you replaced your stock vortec intake manifold with an ls1 intake and a set of headers you will have a pretty decent boost in hp. The stock vortec intake has alot of torque for towing but with the ls1 intake you will gain a few more hp.That's what I'm starting my build off with but I'm going with a little bit bigger cam though. Hope this helps in your cam selection good luck with your build.

Chances are if you do decide to change the cam, yo uare going to have to spend some extra money swapping out other parts.
