2012 1500 5.3L LC9: Thinking about cam...help I've got a 2012 Silverado 5.3L with an LC9. Only thing I've done to it is cat-back duals and a CAI. Looking to install a BTR Stage 4 truck cam along with a 3200 stall, dod delete, long tube headers, and tune. New to camming a truck so had some rookie questions: What range of rwhp gains will I be looking at? How will the low end power be? Is it worth it??

I have a 2012 rcsb 4x4 Silverado lmg 5.3 I over killed it with my cam I went with Texas speed tsunami cam for the ls3 comp trunion upgrade .660 duel valve spring kit. Texas speed has a nice one piece seal and seal kit with the valve springs. Tsp 7.4 hardend pushrods melling select oil pump circle d 3200 stall. Long tubes (1 7/8) ory that merges to duels out the back. Every thing else is stock heads intake etc. dyno tuned by blue cat and truck put down 351 hp to the wheels through a 6l80 tcase and 33 inch mud tires on stock steel wheels.

^^^ yes u will loose some bottom but u make up for it up high. I lost a lot but damn with it just 3300 rpm. I can still pull my trailer with my can am maverick on it and I live in eastern Kentucky. No flat ground here but it still don’t really have a problem.

It will loose a decent amount in the low end, but the higher stall will make up for it some. You may loose 15ish Hp/Tq below 3k rpm, and It wont make power until 3,200 rpm or so, hence why that 3200 stall would be ideal. A 3600 stall might be better.
If you do not want to lose and lowend, at least noticeable lowend, I would not go any larger than the BTR Truck Stage 2. 212/218 .553/.553 113+2, or a TSP 212/218 .600/.660. The TSP 212/218 High Lift cam, last I heard, is the highest HP 212/218 Cam on the market.
That cam should net you around 55-60 rwhp gain. Expect around 350-360 rwhp after longtubes, airaid intake tube, and Tune.
My Truck, 2007.5 NNBS 4x4 with the 5.3, dynoed at 364 rwhp at 5,950 rpm using a BTR Truck Stage 2 Cam. But, I also have TSP-PRC Stage-1 Ported 243 Heads with 63cc chambers running 10.5:1 Compression.
I chose this cam because it would pretty much keep my Hp/Tq Curves the same, but making more Power/Torque at any given RPM, while keeping peak HP at or under 6,000 rpm. I tow often, and wanted to make as much power/torque down low as possible, while making more overall power up to 6k rpm.The Cam really kicks in around 2,500 rpm and pulls hard up to 6,200 rpm. I did loose 5ish Tq at 2,000 rpm, but nothing crazy.
