BTR Truck Norris
anyone running truck norris cam in their C5? after watching a few videos this cam is a torque monster and sounds great. im gonna give BTR a call before i 100% commit but I plan on running 243 ported heads keeping my stock intake since its the ls6 version and add tpis 90mm snout to it with ls2 TB this should help take care of top end? im in an auto so lets be real im not gonna be hanging out in the higher RPM.

I put one in my 01 this past Spring long with ARH headers and Borla catback. It dyno'd at 370/370 and is definitely fun to drive. Like you I was looking for low end grunt as I rarely wring it out on top anyway. I am super happy with the choice and if I want more, I will add a supercharger to the mix.

370 at the wheels, yes? So about 435 crankshaft. For an LS1 that is a nice bump. Most important for this discussion: where is the torque peak, and how broad is the curve? Any chance you could post the graph?

I could see this being an option in an automatic. IMO you could change the valve events some, wider LSA, to carry the power a bit better while giving minimal up low end torque. I wouldn't buy the cam if I was going forced induction.
The Tick stage 3 truck cam is interesting. When I've purchased cams, I've called a few vendors and asked their suggestions. Also have a tuner lined up before you buy the cam if you aren't tuning it yourself.

I forgot to mention that I actually have Richard Holdener's "Low Buck Truck" cam which is nearly (if not) identical to the BTR. I wanted to try this type of cam as a budget build to see how it performs with stock heads, intake, TB, injectors, etc. The car is very fun to drive and has good power everywhere, it is very linear.

Its a pretty small cam, but if low end is your #1 priority its a good choice. It all depends on where your engine normally lives. I went with a slight bigger one that doesn't ever lose low end, but has a bigger top end.

The Truck Norris cam is a solid choice, especially for an auto car where you’ll really feel that low-end torque. Pairing it with ported 243s and the LS6 intake should wake it up nicely. The 90mm/LS2 TB combo will help the top end breathe a bit better, but honestly most of the gain you’ll enjoy will be in the mid-range where that cam shines. Just make sure you’ve got a good tune lined up and maybe think about a higher-stall converter to get the most out of it.

My engine doesn't have a ton done to it. I did the springs and trunions in prep for the cam. Flip tie mod, shorty headers and an axle back. It really rips up top. HP is almost flat 5k-6.5k and shifting puts it right back at 5k. I have LT headers and some heads on order for 'stage 2' but from pretty much zero supporting mods it makes more than a ls6 now.
Here's my dyno tune.

very nice, cam sounds pretty mild not over excessive
