Seeking Input on Truck Norris Cam Specs

I’ve been diving into camshaft specs lately, and I’m particularly interested in the Truck Norris camshaft for LS truck engines. After all the hype, I want to know what makes it stand out.

Here are a few specifics I’m curious about:

  • Lift: What’s the lift on the Truck Norris cam? How does it compare with other cam options for LS trucks?
  • Duration: What’s the duration at .050, and how does that affect the powerband? I’ve read some varying opinions on this.
  • LSA: What LSA (lobe separation angle) do folks typically use with this cam? Are there benefits to varying this spec?

Installation Questions

  • For those who have installed it, how was the process? Any modifications needed that surprised you during the install?
  • Any special tools or tips for getting the best torque numbers?

Performance Expectations

  • What kind of performance gains can I realistically expect? I’m looking to optimize my setup for both street and occasional off-road use.
  • Any experiences with tuning? Does this cam require specific tuning adjustments to run efficiently?
  • How does it perform in terms of fuel economy? I do a bit of highway driving with my truck.

Other Recommendations

If you’ve got any other cam options that might yield similar results or even outperform the Truck Norris, I’m all ears. I want to be informed before pulling the trigger on a purchase!

I appreciate any insights or experiences you can share. Let’s get the conversation going!

The Truck Norris camshaft generally has a lift of around 0.650 inches and a duration of approximately 230 degrees. These specs can significantly improve your engine’s performance, especially in street and drag racing scenarios.

3

That’s a serious lift! I love how it can really wake up a truck’s engine. Does anyone know how it performs at lower RPMs?

4

In my experience, the low-end torque can suffer a bit with that high lift. But it definitely shines in the mid to high RPM range. A perfect cam for more aggressive setups!

5

I’m curious if the Truck Norris cam is compatible with stock heads? I’ve heard mixed opinions on this.

6

Good question! I believe it can work with stock heads, but you might gain better results with performance heads that can handle the lift and duration.

7

If you want to push it further, upgrading your valve springs is a must too! Stock springs may not handle the higher lift well.

8

I’m loving the energy of this thread! The specs are exciting, but has anyone here had a bad experience with Truck Norris?

9

Totally agree! I’ve personally messed up a couple of stock springs because I underestimated the power of a cam like Truck Norris!

Haha, that’s a classic rookie mistake! But I guess we’ve all been there. High lift definitely demands respect.

11

On a more serious note, have any of you done any tuning after installing the Truck Norris? How vital is it?

12

Tuning is crucial! After installing the Truck Norris, you want to dial in the fuel map to handle the enhanced airflow to avoid running too lean.

13

Exactly! A well-tuned setup makes a huge difference in performance. It’s not just about the camshaft specs but how they harmonize with the rest of your engine.

14

Has anyone tried pairing the Truck Norris cam with a supercharger? I hear it can really unleash some power!

15

That sounds wild! I haven’t done it myself, but I’ve heard of some insane results with that combo. Just be sure your supporting mods are up to par!

Reflecting on my build, having the right parts like headers and exhaust can really help capitalizing on the Truck Norris’s potential. It’s like a perfect orchestration!

17

Totally! Each component plays a role in the overall performance. And let’s be honest, having a Truck Norris just feels badass!

18

I’m excited to hear about the Truck Norris camshaft! For installation, I recommend having a solid socket set and a torque wrench. It’s crucial for ensuring everything is tightened to spec.

19

Does anyone know if I need any special tools for the timing gears? I’ve heard it can be tricky.

For timing gears, you really just need a good puller set. Be careful with the timing marks; misalignment can lead to performance issues.
