Question 2015 Sierra Denali 2500 Cam

Two questions:

1) Does anyone know the engine code of the 6.0 in the 2015s?

2) Can anyone recommend a good towing cam for these engines? Preferably one from Comp Cams?

3) Bonus Question: Does anyone know of a good shop that can perform a cam swap and tune in Canada, or a north central state?

Thanks guys.

Should be the L96. Are you going to get headers?

Something in the ball park of a 212/220 114+3 with headers, and a 210/222 114+1 with the stock manifolds. The overlap bias becomes really important when you have stock manifolds.

I will be getting ARH headers yes.. I was just trying to quickly find the engine code on google and found a review of the silverado 2500hd, and it claimed the engine code was LC8. Sounds like a weird code

Spoke to Comp Cams tech, they recommend this cam for the LC8 (assuming thats the engine thats in this unit!)

I have no idea how to read numbers though. I'm thrown off by the massive RPM range. I have a theory in life, anything that does everything is not as good as something that does one thing only. (i.e.: an adjustable wrench doesn't work as well as a combination wrench, and a grill for your kitchen that has 18 attachments doesn't work as well as a bbq)

What do you guys think of this for a towing cam? Truck seems to cruise around 2000 rpm when towing, and doesn't seem to go above 4500 RPM unless your an animal on the throttle. Also I will be installing long tubes on it, my pipe dream is ARH, but I may resort to hooker headers or something of the like. Long tubes for sure though.

That cam would work. Its in the ball park of what I just recommended. That cam is a VVT cam which could help with bottom end power too.

What I had in mind was not.

Yep. It's not safe to go too aggressive on vvt cammed engines. One exception I know is that there's a 2013 camaro ss l99/6l80 that's running an ehi lobed vvt cam that traps 7.0 in the 8th mile all motor lol

Nope. The 6.0 is a carryover for the '15 year model so mod on.

Basically you get a motor that was sitting in a warehouse since like 2011 in your new 2015 truck haha.
