Hey good news.. BTR now has ls9 head gaskets for small bore now. 4.8, and 5.3. Made by the same gm manufacturer

Will be buying them one day soon

If my next toy is LS3 powered, you have my business. 👍💪🇺🇸🦅

How bout boost

Nice

What’s tires on this

I switched to 2116LSR. When I tighten my rocker, it preloads my valve spring instead of pushrod side. Is this normal or are my pushrods too long? I'm not sure if the pump is just that hardcore on them. There's no spring in the cup

King...NA.....!!!!!!!

I wanta go racing to.....hahaaaaaa

Bad ass!!!!!

God...Dang!!!!!!

Fun....fun...fun ........

Internet for the win! Has there ever been a publication or show that did this level of testing with this much consumer involvement? I can't think of anything close. True grassroots and camaraderie. A great thing to watch. Congrats to every single one of you guys. You guys did more than test cams, you redefined media going forward. Just wait and see.

What plugs you guys runnin in gen 6 lt1 416 stroker ???

This video is definitely helpful. Thank You

Great video 💪

Hit it with your purse! 👛😂

Honestly people don’t take responsibility. Trying to warranty something they installed wrong.

This is the new state or "car guy" 😂😂 "How do i spark plug wire"🥴 warranty!? for real bro. . . Take your Hellcat back to the dealer bro☠️

So sad that you have to make this video.

Lol.."Hit it with your wife's purse"

Can I send y'all my block for a rebuild?

It is stock cam, stock heads, stock fuel system and stock converter The mid list printed above has another customers list in it. I’ll get them to fix it

Why not ADD a Pro Charger or turbos and see how much more than 1000HP you get? After all ETS just added twin turbo's and went 8.64 @ 170 MPH ( see video on youtube!) in the quarter? Surely YOUR HEADS AND CAM with a supercharger or/and turbo's SHOULD easily beat that time! After all power at the track is what it is all about, or WHY BUILD IT?

After listening to and watching this video of your approach to camshaft design I decided to subscribe, It's nice to see a humble approach to your success. Thanks for competing and sharing your knowledge.

GPI is and has been at the forefront of LS and LT piwer and reliability for a while. I’ve used them multiple times and they always NAIL it. I’ve worked directly with Ryan on a few of my custom cams for our drift cars and drag cars and they always exceed expectations. Very few people understand valvetrain as well as these guys and this proves it. Great job as usual guys🥳🥳

Hi, I have a LT4 in a Camaro. I wanted a BTR cam, but the guy that built and tuned the motor had you guys port the heads and used your cam, At that point I had never heard of GPI....lol. You fellas should be very proud of yourselves! Congrats!!!

Thanks for the update! Some one should make a magazine!!

I hope to see these contests become a staple in our industry. There’s no better marketing than proof in the puddin

Are there any other mods necessary to do this to a stock motor?

Thank you for your entry and info. You are a real asset to the community and are greatly appreciated!

Engine setup ?

Nice setup

Long Live Dolph 🐬

Are they publishing comparison curves?

I can't wait... One day ima bring my ls3 5th generation for a stage 2 or 3 cam install

thanks for sharing your thoughts on this. Congratulations for doing very good in the challenge !

Thank you for mentioning your specs, I’m really interested in camshaft theory and many people are super secretive about their specs. Congratulations on your results! You beat out some big names.

Great video sir , congratulations on a fabulous result. Thx you for explaining your strategy and cam specs.

I thought Eric did a great job not sure how he got done .

You guys have done the community proud with your results. GWATNEY already resides in the upper thought echelon along names like CID, BTR, MAST and even LME, as Tier 1 Gen 3/4/5 Chevy SB Professionals. This Competition frankly just backed up Gwatney's already long line of successes and records. Something tells me that if this were an EFI setup, that competitor's such as yourself would have been leaps and bounds ahead of others. I love seeing shops go head to head. No losers, all winners, as everyone who entered their Cam into the public arena had balls.

Great job Gwatney performance I am happy your doing video there’s a lot to it more then people realize. You did well man .

The cam challenge was fun, I put in a guess in, My guess= Intake 239 @ .050"-.650" lift / Exhaust 247 @ .050"- .659" lift / LSA=108, hats of to Eric he did an awesome job, it was exciting and informative, congrats to GPI on 2nd place

Was nice to meet you sir!

hats off to all, you all desaerve a pat on the back, everyone won--- data data data on ya eric

Great job! It was a great contest, and it was a ton of fun to be a part of it!

Thanks for sharing your work and the details involved.

Not surprised GPI did really well. I have GPI CNC ported heads, intake and throttle body on my 5th gen tuned in house by Ben and it has exceeded my expectations. The folks at GPI are very passionate and very good at what they do. Congratulations!

Air in, air out. Doesn't matter how you get it in or out . The more the better.
