I just put the truck norris cam in my 5.3 and it's a very nice cam sounds great, my other 5.3 has a trick flow 30602004 cam and the power difference is not even in the same zip code the 5.3 with the trick flow cam seems to make much better power but I'm still happy with my BTR cam and plan on keeping it
The Truck Norris cam is for pickup truck guys who want to be able to get away with a stock torque converter (212/220). It's also a really good driver cam that has good sound and some punch. That Trick Flow cam is called the Track Max (238/242). There should be a massive performance difference between those two cams.
I'm putting the Truck Norris cam in a 6.0 for my '93 obs truck. REALLY hoping I don't regret going with 2.5" dual exhaust, x-pipe, and Magna Flow knock-offs.
I would of thought it make more than that stock and after the cam swap, I like to know how some people dyno pull a stock 5.3 and are getting roughly around 330-340hp stock
It wouldn't make sense for anyone to get that kind of power from a stock port injected 5.3. This is rear wheel horsepower. Not engine dyno flywheel horsepower, and port injected 5.3s were rated at much less than 350 hp. Factory ratings are flywheel horsepower, not rear wheel horsepower. There is about a 20% loss in power through the drivetrain to the wheels. Rear wheel hp numbers are about 20% lower than factory flywheel numbers. Post 2014 5.3s are direct injected and are rated at 350 hp at the flywheel, but that is not a rear wheel horsepower number either. Of course, the engine in this video is a 4.8, not a 5.3. For 350 rear wheel horsepower stock, you'd be looking more at an LS3 6.2. 350 wheel horsepower is about 440 hp at the flywheel.
Sounds great now.

It'll hurt your numbers a little versus 3 inch, but its definitely not going to be a build-crushing restriction.
👍👍👍
Wondering what this cam would do in a 5.7 LS1 with the 4L60e stock converter combo.

What rpm did have in gear /idle
1st comment 🤣
Go sell your car!
@@Scramspeed I did … it’s staying local and he picks it up next week 😕
Sounds awesome
Why such a small engine in that?? Ugh😢
