I’ve been diving into some upgrades for my 454 big block and I’m at the stage where I really want to get the best cam for my setup. I know there are a ton of options out there and everyone seems to have their favorites, but I’m hoping to gather some solid recommendations and insights from those who’ve been through this process.
Why a Good Cam Matters
Choosing the right camshaft can dramatically change the behavior of the engine, affecting everything from torque to how well it revs. Since I’m aiming for better performance on the street and maybe some time at the track, I need something that balances power and drivability.
What I’m Looking For
Performance: I’m looking for a cam that will enhance performance but not kill low-end torque.
Sound: A nice growl would be a bonus!
Compatibility: It should work well with my existing setup (intake, headers, etc.).
Street-Friendly: Absolutely want it to be street-legal and reliable.
Current Setup
I have a mostly stock setup with some minor upgrades (like headers and an aftermarket intake), but I’m considering more significant changes down the line, like a better carburetor.
Questions to Consider:
What cam specs should I be looking at?
Any particular brands you all recommend?
What kind of gains have you seen with your cam choices on a 454?
I appreciate any help and am looking forward to hearing about your experiences. If there are specific part numbers or setups that worked really well for you, please share! Thank you!
I’m glad you’re considering camshaft profiles for your 454 big block! It’s critical to evaluate lift and duration. Higher lift can increase airflow, while longer duration can shift your power band up. What kind of performance are you aiming for?
You make a solid point! Additionally, don’t overlook lobe separation. A narrower separation typically gives you a looser idle and more low-end torque, which is great for street applications.
I’ve been eyeing the Comp Cams XE series for my 454. I find their lift and duration specs really get the most out of an engine like ours! Has anyone had experience with these cams?
Absolutely! The XE284H has been a game changer for mine. It gives a great horsepower boost while maintaining drivability. Just ensure you have the right supporting mods.
Are you guys looking into roller cams or flat tappet? Roller cams can really up your performance without much wear and tear. Curious what you all prefer!
That’s an interesting question, gina02! Roller cams are definitely more efficient. But some love the traditional sound and feel of flat tappet in big blocks. What do you think influences that choice more, nostalgia or performance?
I’ve read that the lobe separation angle can really impact how an engine behaves at different RPMs. Does anyone have input on what angles work best for the 454 in a street application?
For street applications, 112° to 114° lobe separation is often a sweet spot, balancing both torque and horsepower. It makes cruising more enjoyable without being too rough.
It’s also worth noting that each cam profile can profoundly change the engine’s character. If you want a lopey idle, aim for higher duration with a lower lobe separation. It’s all about that sound and feel!
Choosing the right cam for a 454 Big Block can significantly impact performance. It’s essential to consider how the cam works with your intake manifold and cylinder heads. I’ve seen some great setups with the Edelbrock Performer series.
Don’t forget to account for your desired horsepower and torque goals when selecting a cam. The right camshaft can make or break your build! What’s your intended use, like street or track?
