Generation IV Internal Engine - 6.2L L92 L76 intake NW 90mm what cam is good

hello everyone,
i'm swapping a 2007 escalade L92 6.2L aluminum engine into my 1999 blazer with a t56 6 speed dodge viper spec tranny L76 intake w/ Nick Williams 90mm throttle, sanderson headers.:D efilive v2 programmer to do the tunning.
and maybe a 3.43 rear or higher not sure yet.

now i am looking for cam and need to now what has to be done. this engine comes with the VVT variable valve timing. is it a good idea to eliminated it and go for a bigger cam or do i leave the vvt stock cam there.
i'm gonna be driving it in the streets but dont want it to sound too chopy.
something that i can have fun with on the street and on the track and save a little gas.
am i asking for too much?:confused:
thanks in advance

What PCM are you using?

I think the reluctor wheel isnt going to work if you are using the 99 one.

i'm using the e67 pcm with a stock program for the engine now and a t56 for the tranny. i'm having trouble looking for a cam for this engine, since it has vvt

You will probably have to work really hard finding a cam. I am not for sure if anyone is offering one right now. We have been doing some work with Mast Motorsports on their turn-key engines using VVT and their controller. They have made some good power with just a cam swap. I will check on the availability of just a cam as they weren't selling just the cams originally.

Look at Mast Motorsports. I think they offer a VVT cam that will work with the L92.

I got my my L92 without VVT. SDPC replaced the covers and other parts with LS2 units. But, I am also looking for a good cam to work with the L92 combo/6.2. Happy for any advice....

what parts did you have to change to put another cam in it. and do you have part numbers that'll help out alot thanks :bang:

I'm curious about this too. subscribing

i think that if the cam phaser can bolt on to any cam then where good to go with any ls3 cam. from what i've been reading the cam phaser turns on at cruising speed, and turns of when you give some gas or going uphill. i'm gonna look for some pics of the cam phaser and post them here, to me it looks like the cam phaser bolts on to the front of any cam.

I got the L92 from Brian at SDPC. Hopefully Brian can step in and put some light in the work they done at SDPC. We went without VVT, because will run it with the (former UMI-Racing, now MSD) InGenius PCM. Will keep you updated as soon as it runs.Thanks

yeah give some part number or even a package deal to eliminate the vvt. that sounds very good....

Interested in this as well.

I'm doing the same thing except into a ws6.

remember it's basically an ls2 with 12 more ci. and better heads from the factory. change a few parts and it's like doing an ls2 conversion.

you're biggest obstacle is finding a proven cam for a stock displacement l92 that fits without flycutting.
good luck.

I Think I Now Mast Motorsports Secret Ha Ha Ha Ha Haa They Add A Performance Cam Wich Has 3 Bolts For The Sprocket And Use An Adapter To Keep The Center Bolt As The Stock Cam Comes And Whuala You Have A Nice Cam Upgrade With Vvt... Ha Ha Ha Haha Ha Aah Hahahaha Been Looking Around To Much Info And Now I Think I Got It.... I Feel Like Trying It....

this is the cam phaser i have on the 6.2L L92

now click on the attachment and see if that will work
This kit allows for a proper installation of an aftermarket cam on a 2007 or newer Trailblazer SS or Corvette. These vehicles have a newer cam design to go along with the variable valve timing available on some of the other GenIV motors. Simply using an older LS2 cam sprocket will not be good enough because of the differences between the ECM’s.

yeah you have to use the 4x cam sproclet (06 up) for your ecm. so youre ditching the cam phaser but keeping vvt? I'd ditch the vvt if youre gonna cam it tho.

so how do i keep all the stuff and just change the cam

i wonder how it'll sound a nice beefy cam running on 4 cylinders with alll this vvt stuff. i would like to keep all of this stuff, i see a big future in the vvt

i see a big future in the vvt

Definitely interesting... I wonder if there are performance gains to be had with it?

ohh yeah there are performance gains there is a post on this ls1tech site where they showed some dyno graphs with and without the vvt. if i find it i'll link it

i think i'mma go without the vvt and also eliminate the cam phaser.
i know i need this

http://www.ls1speed.com/cont.cfm?cid=C0000752

now what cam can i go with maybe a gm hotcam or LS3 or a LS7 cam i need a cam that wont touch the pistons i dont want to flycut the pistons...

Whats the max lift/duration that can be stuffed into one of these without flycutting?

i would like to know also

me too!

Lots of LS3/L92 mod info in the c6 section over at corvetteforum guys. lots

ohh forget it i'mma swap out the cam and eliminate the vvt.

what cam can i put without having to change pistons

I've read a lot of posts about not needing to use huge cams with these heads. Seems the 224-228 range is popular

what kind of horsepower am i looking at for a L92 6.2L, GMPP L76 intake, 40lbs injectors, 90MM Nick Williams throttle, with a 224-228 range cam. i'm thinking at least 500hp am i close to that or is it more or less than, and it'll be mated to a t56 viper spec that could take 650 ft lbs of torque

500 is a big mark from what I've read the 480 range is more typical and 500 more the exception. You seriously have to join Corvetteforum man theres a LOT of info on this over there.

I have a SSTB with LS2 engine Rick Hollenback from Synergy Motorsports designed me a killer cam for my L92 heads & long tube headers motor. It is for a heavy SUV/Truck to get it moving with killer torque off the line. Nice choppy idle not extreme with great street manners also computer friendly no PTV clearance issues. Watch trying to go too big on the cam it kills these heavy trucks. All the fast SSTB's are running milder cams or it won't 60 ft good. My cam is killer that Rick designed covers the low/mids with big torque off idle to over 6k. I ran 12.12 @113 before now looking at low 11's high 10's with my new MT DR's 305-45-18" for much needed traction. LOL use regular cam & junk the VVT stuff.

care to share your cam specs? PErhaps post the spec sheet? pretty please....lol

Buy it from rick, or do your own homework and figure out what you think will work best for your effort.

If you dont want to figure it all out, find a competent tuner in your area, and let them help you.

Just like I did..... after yall didnt call me back:punch:


Peace:gtfo:


No biggie........I dont have a Corvette owner budget.... but hey... I did pay more than 420 for a cam:D

Thanks. thats good advice, and asking someone who loves their setup IS DOING MY OWN HOMEWORK. Maybe next time you have an urge to be a dick, you can save it for someone who is speaking to you.
If he doesnt want to share his cam specs, thats understandable and fine. He is a big boy and can speak for himself.

Because a lot of people pick a cam from someones combo, and then try to piece together a combo and it doesnt perform. Then they get on here and complain why it doesnt make power.

Im not being a dick, Im merely stating what I have seen since the inception of the LS1, and how this board tends to ride cam specs. Its not about that, its about what makes you happy, and the entire combo and what YOU want it to do. Do some research, make some phone calls, talk to some people who have done it, or experimented and then make your educated guess.

Being a dick isnt my gig, and Im sorry it came across that way. I pick up the pieces with a lot of combos every day, and If I can help one person with their initial setup and them be happy, Ive done my job :)

My apologies then. YOu are absolutely right about the cam riding. I often see people (when i am doing my research, lol) asking other people for their cam specs because they like that persons numbers, like it is going to work for them.

again, sorry for taking it the wrong way. Appreciate the heads up.

Rick put mine together based on my mods (L92 heads, 2800-3000 stall & LT headers) also the weight of my auto. He figured what would work also that i wanted good street manners. 22x/22x, .58x/.59x on LSA116 that is about all i can share other then intake & exhaust are ground on different lobes. Mild cam but works for my combo. That is as much as I can share to be fair to Rick. I promised not to share cam card on his research to him. I understand why on his part but the above will give you a idea the rest just get with Rick he will sell a cam just for your engine for a normal going price. I did a lot of research & hardly anyone shared much more on a pure custom grind. He was fair with me & it did all he said it would. Rick & Lewis are the guys that seem to have a good handle on their combo's. Price was real fair.

cool. Cam seems to be a reasonable size for the street. Thanks.

I agree 100%.... HOPEFULLY THE CAM foots the bill and I gain from it not taking a step backwards.

as far as my cam from Synergy: it is a 23X/23X .6XX/.6XX on a 114+4......... but unless you know what lobe it is on the duration numbers only tell part of the story. :nod:

BINGO! well spoken!
There is thrill in the HUNT!
It's a sense of accomplishment when it all falls together!:cheers:

After this past weekend I am going to half to say the G5X3. If you haven't been following my post in the dyno section you should take a look at the torque on that thing.
