It has Chop
This Brian Tooley Truck Norris cam definitely has a chop to it. My truck has decent power with this cam. It is drivable, but you’ll notice it at stoplights. Personally, I could use a little more power with a little less chop, but it’s a good cam. Just remember, your real gains over stock are somewhere between 4500 to 6500 rpm’s. I found out that the transmission shifting at 5300 rpm’s is a bit hard on the transmission. I’m repairing it now, lol.

Sounds good, pulls hard, stock ECU no tune
05 Sierra 5.3 2wd, Monsoon intake and MBRP single side 3” catback exhaust. Throaty deep tone and excellent chop to it. Sounds rowdy for an easy cam setup. A noticeable bit quicker for the butt dyno. But for just the smile it’s gonna put on your face lol

Awesome
Installed this Truck norris camshaft kit onto my 93 sierra ls swapped , love the power it makes , fun to drive , would definetly recommend if you dont know what cam to choose . I did not know what cam to get since theres so many out there, after so many reviews and comparing lots of brands and cams i decided this one is overall great among the others.

Don’t over think about it and just do it.
I was nervous on buying this cam kit off Amazon, but I did anyway. I built a lq9 6.0l to replace my 4.8l in my 99 single cab Silverado. Got the cam installed it in the motor and dropped the motor in a week later then drove it for a week before the tune. When I till I I have a while another beast, “bruh”. I wanna buy another cam kit for my Monte Carlo LS swap 5.3 5 speed. Truck Norris cam kit is a straight beast men. I wanna upload a video of the chopping. Straight popcorn.

Great sound and power
I installed this cam and springs on my 2012 GMC Sierra 1500 5.3l, 6l80, 4X4. I had it dyno'd after the fact and I came in at 294hp and 365 torque to the wheels. The sound difference it worth it. I would recommend it to others.
