Seeking Cam Specs for LS6 454 Engine

I’m diving into a project with my LS6 454 engine, and I’m trying to find the right camshaft specifications to optimize its performance. I’m especially interested in details like:

  • Lift
  • Duration
  • Lobe Separation Angle
  • Any additional performance characteristics that might be relevant.

I’ve heard a lot about how the right cam can completely change the character of the engine and improve both power and efficiency. Whether for street or strip use, there’s definitely a lot to consider.

Questions I Have:

  1. What are the most popular cam specs that people recommend for this engine?
  2. Are there specific brands that have proven to be effective?
  3. What kind of performance gains can I expect by switching to a new cam?
  4. Should I be considering any other modifications that pair well with a camshaft upgrade?

Any advice or experiences you guys could share would be hugely appreciated! I’m looking to get my Chevy working at its best and, as they say, there’s no such thing as too much power! Looking forward to your suggestions and insights!

Hey everyone! I’m trying to find the cam specs for my LS6 454. Specifically, I’m looking for lift, duration, and lobe separation angle. Any insights would be greatly appreciated!

3

The LS6 454 typically has a lift around 0.515 inches, duration at .050" of around 230 degrees, and a lobe separation angle of 110 degrees. These specs are vital for understanding your engine’s performance!

4

That’s a solid starting point. I’m wondering how different lifts affect torque and horsepower. Anyone have performance data?

5

Higher lift generally increases airflow, potentially leading to better torque and horsepower, but it can also depend on other factors like the intake and exhaust systems. What setup do you have?

6

I think the duration plays a large role too! The longer the duration, the higher the power band. But it can sacrifice low-end torque. It’s a fine balance!

7

Exactly! I find it fascinating how choosing lobe separation angles can affect the engine’s behavior. Has anyone experienced tuning issues?

I’ve had some tuning challenges! After changing the camshaft, I experienced some rough idling. I think it’s due to overlap from the specs. Anyone faced similar issues?

9

Yeah, that overlap can really mess with things. It’s essential to adjust your fuel mixture to match the new cam profile.

10

Totally agree! It’s almost like an art form—engine tuning. Finding that sweet spot between specs and performance takes time!

11

Can anyone explain how the lobe separation angle impacts idle quality? I’m curious if a wider angle improves it.

12

Yes, generally a wider lobe separation can lead to a smoother idle and better drivability at lower RPMs!

13

Absolutely! I’ve learned that every combination is unique. Reflecting back on my first build, it was all trial and error. Now, I feel more confident with these specs!

14

I’m also looking for LS6 454 cam specs! I’ve heard a lot about the Brian Tooley Racing cams being a great option for street performance. Can anyone share their experiences?

15

I just installed a BTR cam and it really woke up my LS6! The mid-range performance is fantastic. Highly recommend it!

I’ve been considering a Texas Speed cam. They seem to provide a good balance between performance and daily drivability. Anyone have feedback on that?

17

I have a Texas Speed cam and it’s solid! Just make sure to pair it with a good set of headers for max power.

18

What about the Comp Cams? I’ve read they have good options too but I’m curious how they stack up against BTR or Texas Speed.

19

Comp Cams are definitely a solid choice. They have some great lift options that can enhance high-RPM performance, but can be a bit noisy.

20

It’s essential to consider your driving style. Are you going for a daily driver setup or a pure performance machine? It really dictates the cam choice.
