6.2L LS3 CAM TEST-STOCK VS STAGES 1-3 WITH STOCK HEADS & STAGE 1-3 WITH CNC PORTED AFR LS3 HEADS. 

Right. Cam stages are really only relevant as a way of comparing each manufacturers cam models. For instance, I run a GPI stage 1 LS3 cam. The lift on this cam is much higher(647/638) compared to some other companies stage 3 cams, albeit the duration and overlap is rather mild at 224/237, 7º. So basically, stages make little sense between different cam companies.

its usually duration that matters not peak lift

@@WildEngineering theres a ton more to cams than just lift and duration for sure but seems most people spec cams off of sound, not performance.

@@madmod yeah its weird that people would rather have "chop" than proper set up HP

@@madmod Youre talking very minimal differences. I mean even the "stage 3" cams here didnt lose any power down low. Even bigger cams would keep gaining up top and only lose very minimally down low. Unless youre in a strict class racing it doesnt really matter.

Whats ur current setup ??

@@kevincantu1238 the 1LE was stock 3.91 rear, stock LS3(no head work) w/btr stage 3 cam, pushrods, springs, retainers and polished throttle. Cold air intake and longtube headers.

I'm honestly surprised vendors haven't done this yet for their stages. btr and tsp kind of do it now for some of them but not an actual comprehensive graph or spreadsheet like you said.

Thanks 🔥

That should make more power but not as much as these cams. That cam was made for smaller displacement motors but it should make good power and it’s supposed to have more low end torque than stock down low

my 2002 WS6 LS1 stock block, heads,and LS6 intake with a RPM5 cam basically an old MS3 spec cam put down 414/390 also on a mustang dyno thru a Yank 4k stall convertor and was also a daily for 12 years never an issue driving

I have not

How did it do? Swapping from a 4.8 with chopacabra cam to a 6.0 and trying to find the best cam to go with

@@JC-dj5hj The truck never made it on the dyno but it's fast and fun...

endless 6.0l cam and boost videos up-same results

No ls2’s are wack

you need to drop the valve size down on the LS3 head to improve CoD

much bigger difference on heads for a 5.0l

cath ports might gain more from head flow-the rec ports already flow a ton

@@richardholdener1727 I swear you did some similar tests in the past, just haven't been able to find out if you've done anything with better flowing heads than stock and a smallish cam. I remember the 4.8/5.3 test with the TEA 706s, Crane 224/232 cam, FAST LSXRT, etc. I swear that you said that the heads helped, but the gains weren't that big all things considered. That 224/232 cam is larger than the TN.

​@richardholdener1727 second to last test the "227" cam or stage 2 would you see much increase if raise a full point on static compression @same advance just better fuel?

if it adds power na-it adds power SC

see the many intake videos I have up-the gains would only come up top-with losses through much of the curve

small

@@richardholdener1727 decided to go with 212/218 .550/.550 112 LSA from TSP. We’ll see how it does. I really didn’t want too much chop.

I have some for sale (cheap)-email me

@@richardholdener1727I have a 2012 Yukon with the L92 6.2. What exactly would I need to go along with a stage 2 cam? It’s my daily I’m just looking for at least 50+ hp

I’m throwing a LS 3 in my 06 four-door z71 I wanna run e85 FBO what can you recommend I also have a v3 sc1 I’ll throw on later down the road when I get bored of N/a

with very rare exception, every na motor I run is on 91 pump gas

Do you have any recommendations for camshafts for the above stroker?

I have not

Yup, this

that is you missing the point

@@richardholdener1727 I am not clear,? What is the objective? Cam only vs cam plus heads should be same cam used as a contol. Unless AFR or cam manufacturer disagrees? I.e. the gains are embarrasing?

On an engine dyno, no accessories fitted etc.

We made 470whp/470wtq with a bolt on ls3. They'll make more power than he shows.

@@HioSSilver1999 I made the same using a mild cam and headers with an LS3 intake on a L92.

ea my 02 WS6 made 414rwhp with stock 241 heads and a RPM5 cam similar to the MS3 specs

Hi so its doing that with a stock ls3?im thinking the same for my 2010 Camaro ss

My 2011 Camaro SS with a new GM performance LS3 495 crate engine with CNC ported and milled LS3 heads tuned and running on E85 made 430 horsepower at 6200rpm and 410 foot pounds of torque at 5000rpm at the wheels has a ton of upgrades a aluminium one piece drive shaft a built 6L80E transmission with a circle D 4200rpm stall converter stock 3.27 gears with a Auburn limited slip with suspension mods and drag radials has gone 7.22 at 96mph in the eighth and 11.28 at 122.7mph in the quarter mile it makes good horsepower and torque to the 6600rpm redline shift point and does 1.71 60 foot times

@@gloriamaletta8667 Nice ride! Either my dyno shop is overrating me, or yours is underrating you!🙂

My engine on a engine dyno made 520 at 6200rpm and 490 torque at 5000rpm with 26 degrees timing and running E85 but it has a pretty loose 4200rpm stall converter

@@gloriamaletta8667 your 60ft needs improvement especially with that 4200 stall but im sure once you iron that out you will be in the 6s in the 1/8

If you're constantly at full throttle or only care about that torque converters will definitely even the playing field at all time. As someone that barely flashes their converter is where you'll notice the difference. If you're looking for real performance though 3k converter will dissapoint lol

@@hayden6056 Turbo SUV, not throwing a 5,000 stall in it. But at the same time don’t want to give up 25hp up top. With a 3k stall, you can have the bigger cam without losing out on torque the only place big cams seem to lose out on torque- below 3k.

@@boost1728 depending of level of traction and what you're trying to do a high performance stall should always be set 500 rpm below peak torque. Also be aware that a stall will usually lose you turbo response because you don't have as much resistance to spool it up.

@@hayden6056 I agree with traction but disagree with your converter recommendation- you don’t want a 4k stall in a tow truck.. ideal stall depends entirely on the vehicles purpose. And a higher stall will absolutely not lose turbo response. The higher RPM you can load the turbo up at, the better…. Notice the fastest turbo LS cars running 5k+ stalls leaving on 20psi? Good luck doing that with a stock converter or a manual transmission without launch control.

@@boost1728 fair enough , it's how I've always had my stalls built , I don't understand why you'd need to flash the converter that hard with all that power while towing personally. Chassis not rated to pull something that has the same amount of torque as a truck rated for a 30 tonne load. Shouldn't need to have your foot in to it constantly. When I went to a taller gear my car spooled up faster with no other changes . When I went to a lower flash rate stall it also became more responsive. A torque converter when it's not hit flash point doesn't have the resistance to build exhaust pressure as easily. The more load on the motor the faster the turbo spools. Hence why third gear and above you're peak boost comes in earlier than first and second if you have traction. You can even test it on a chassis dyno. I've had as bigger difference as 700 rpm depending which gear I was in on laggy set ups. You're obviously an expert in the field so as someone with a lower knowledgeable amount on this subject theirs no use me contributing any further you already know everything. Hope your build turns out to be everything you hoped for.

makes less than the 224 or 223 cams

There’s plenty of videos with it and it’s an outdated cam. I think the truck Norris cam made more power and that cam doesn’t even require a stall converter

makes no difference in power using factory ECU-just takes too long for programming

@@richardholdener1727 I'd be curious about that. Also, we could see tests with VVT VS NO VVT. There are advantages to both approaches. Thanks for all you do Richard!

What kind of a gain would shorter intake runners get. Are these cams too small for 7500rpm
