C7 Corvette: Headers Worth It With a Cam? DYNO TESTED!
HTML-код
- Опубликовано: 6 мар 2022
- One question we get regularly: "do I really need long-tube headers with a camshaft upgrade?" The answer is an obvious yes, right? And while most start with intake & headers before doing a camshaft, it occurred to us that we've never tested the opposite approach. And in this video, we do exactly that to answer exactly how much power headers are worth on this GPI SS3 cam'd C7 Corvette!

Short and to the point, clearly established objective and not loud bs music.
Thumbs up!
Man the c7 corvette grand sport is my dream car!! I need some money 😂
Great videos guys keep them up
Wow, such a great educational video! Thanks for taking the time to post this. As a new C7 Stingray owner this video made me definitely get headers along with a cam. Thanks again! :)
I love the sound! What did you change on the exhaust and what brand? Thanks again!
VERY interested to see what mine picks up! I have them ordered and hope to make larger hp gain with my supercharger pully being changed as well. My c7 grand sport already has a stage one cam, Lt4 supercharger, Lt4 fuel injectors, Lt4 fuel pump, AFE Momentum cold air intake, upgraded Edelbrock cooling system, an active fuel management delete kit, and forged racing pistons. I'm now going in for the Stainless Works long tube headers, high flow cat with x-pipe, and putting a smaller 2.3 pully on the supercharger.
This the video I needed. I have a 6th gen Camaro SS with an LT1. I’ve been trying to plan out upgrades. Started with cat back exhaust. Next I want intake and headers. Then later I’ll get the camshaft I want. My hesitation was wondering if I needed heads to go along with the camshaft. But this lets me know it’s ok to go 1 small step at a time. Great video.
Thanks! We enjoy making these types of videos.
Loved the information. Just bought 2015 Z51 and looking to install Cam/Headers/and turbo charger. Any recommendations?
So I've got a full heads cam,Intake manifold. Everything you can do without E85. do recommend one heat range cooler than stock on the spark plugs? Also what you set gap to? Thanks and love your vids guys
I bet a lightweight C/F driveshaft would help a bunch as well.
The undercarriage is a work of engineering art 👏🏽
do I need to change the gaskets and spark plugs when installing headers or would I be fine just installing them?
Can y’all do long tube headers on a’13 Escalade with a cam and supercharger?
Can you list cam and headers used on this build to get for mine :P
great vid.i have an 18 gr.sport..ive had a custom exhaust with the mufflers deleted + the secondary cat..question is putting long tube headers on alone without changing the camshaft....is it worth it now??? + oh n plus i put an afe cold air intake on it.
no reply...just-groovy...LOL...
Yes, absolutely! Check out our Stage 2 Performance Package for C7 Grand Sport here: nationalspeedinc.com/packages/gm/corvette/2014-2019-c7/c7-grand-sport/
Sorry for the late reply, catching up on responses now!
Will it pass smog? I'm looking into buying a C7 7 speed.
At what stage cam do you have to upgrade the torque converter on an A8?
This is more of a question of comfortable idle speed than a cam stage. We have a cam spec that is good to operate and idle well within the ranges of the stock TC, we include it in our "Stage 4 Auto C7" Package. Anything above that, we recommend TCs.
Who makes the best quite cams not a fan of that cam sound
so, what cam is this. also, I have an LT1 A8, what is the best cam i could get without changing the torque converter
Feel free to check out our performance packages for Corvettes here: nationalspeedinc.com/packages/gm/corvette/
There are cam options and explanations for which ones need torque converters and which ones do not.
What type of long term issues do you run into after installing an aftermarket camshaft?
None
Lifter failure
@@tweakhawaii362 need to upgrade those too?
@@josephraines4338 yes definitely, make sure whoever is installing it is reputable. With an after market cam, its recommended you upgrade the entire valve train. I bought a 07 C6 with an aftermarket cam, drove it for 2 weeks, lifters failed (could hear a tick in the engine)... When upgrading my heads cam the mechanic found score marks/dents on the camshaft, had to get a new block entirely. Now im going with a forged 408 with forged internals. 11k down the rabbit hole for me LOL
@@tweakhawaii362 Damn!
Best compassion wouldve been stock manifolds with no cats, active mufflers...
Then headers with no cats and active mufflers
@1:34 Banana
What’s the itemized cost? Thanks!
Hey Theo, it varies a bit depending on year and vehicle trim. I encourage you to reach out to a Performance Consultant, we'd be glad to chat! nationalspeedinc.com/contact/
so nobody else noticed the banana 1:33
?
?
I’m new to the car scene so his car messed up with the cam he had so he had to upgrade it ?
One of the AFM (Active Fuel Management) lifters collapsed, which requires an invasive repair. The camshaft had some scoring on the lobe as a result, so he took the opportunity to upgrade, since the scope-of-work isn't much different from simply repairing.
@@NationalSpeedInc ANY-1 WHOO HAS A NICE CAR LIKE THIS..WELL IS A FOOO IF HE HAS THE CAMSHAFT CHANGED..THIS ENGINE IS NOT BUILT 4 IT..+ IT WILL DEFF..VOID YER WARRANTY + WHEN U GO 2 SELL IT IN THE NEAR FYTURE..NO-1 WANTS SOMEONES ...HOT-ROD!!..NUFF-SAID.
How much would all this cost with installation?
A bunch
Hes Santa clause and Christmas is every time the car breaks from those nifty upgrades,keep it stock with a warranty.
My 2016 Camaro SS has been supercharged for over 5 years now.
No issues
I've had multiple cammed LS cars that had zero issues also
Over 60k miles on all of them
Are long tube headers street legal?
Nice...manual or auto
Manual transmission.
i saw the banana
We love the banana.
