I've got a 2011 Colorado with the 5.3 (LH9). I'm planning a cam swap with a 210/218 .551/.551 Crane 3-bolt cam. My stock setup has a 1-bolt cam with VVT. I already have a new non-VVT front cover with cam sensor and a set of LS6 springs. So what timing set do I need? I'm thinking a LS2 set will work but want to be sure. Need help!!!
P.S. Keeping the VVT is not an option so please don't try to talk me out of it.
I'm pretty sure you need the x4 cam sprocket ls3 timing set.

I also believe it's the x4, but you should also think about changing that Ls6 spring for a better after market piece. Your pretty much making them out. I had on my hotcam with 1.8 Harland sharps and I started getting valve float on the dyno for a retune. Just my .02
