LS3/L92 Cam selection considering TX Speed I just picked up a 08 L92/LS3 intake with a 6L80E out of a 08 Escalade which will be going into a 70 Chevelle.
I spoke with Texas Speed and their Cam package 229/236 624"/615" claims 567 Max Power at the flywheel.
Has anyone had any experience with this cam package as well as drivability?
*Can a cam package increase HP from 403 to 567 wth a tune?
*What other mods are needed to free up the powere?
*What stall should I go with on the Torque Convertor?
Thanks

My LS2 with LS3 heads/intake and 227/239 .614/.624 115+3 should be somewhere close to 540hp at the flywheel I suspect ...so I don't see why with that cam and larger bore 6.2 it woudn't reach 567 flywheel...
and I agree, they LS3 and L92 are the same motor. I started with a L92 myself. just curious where you got a baseline for the HP on that combo? "should be somewhere 540hp I suspect" sounds like a pretty vague idea of what kind of power you might possbly make. Genuinely interested, not busting your *****. Like I said, im running a L92/LS3 myself with the cam I mentioned above, and I have no idea where im going to land on HP. I was hoping for 500-515 crank, looks like I may exceed that....

My baseline idea is based off of threads on here and threads on other forums as well...I wasn't really chasing a number...I was more or less going for a strong streetable/track motor...But I'm sure you'll be over your personal goal and I should be close to mine....
sounds good. ill be watching your build on s10forum.
Probably going to need a decent sized stall for that cam. As for power levels? Sounds about right from what i've seen but that cam will be on the edge of civility and street manners. The tune will be paramount to making it civilized but power wise it should fly.
As for stall? Im guessing your ditching the VVT correct? If so I'd be looking at a Vig around 3200 or thereabouts for starters. Not sure if you have Vigilante stall experience but they tend to flash quite a bit higher than advertised stall speeds compared to lesser brands. I also really like Coan for all out race and Art Carr, Yank, Edge, all decent too but again "advertised" stall speeds vary from brand to brand so ask their tech support a LOT of questions and provide as much info as you can and you'll fare well.
I like Vig because you get one free re-stall thats good for a year. Picking the right converter first time out is tricky and this adds some redundancy to your build.
I probably dont have to mention this considering the caliber of your build going by your engine etc but the saying "You get what you pay for" holds true as anything when talking about stall converters.
Good luck

I spoke with Matt and Texas Speed and I went with the 229/236 cam package he suggested. Matt also suggested the 3000-3200 VIG so I'll go that route as well. This combo should put me around 550 HP at the flywheel as per TX Speed.
I now need to figure out what kind of shifter to go with and what else I'll need to hook it up. My tranny is a 6L80E. Any help would be appreciated.

Thanks for your time.
If you swap from VVT over to a static cam then you have to change a few supporting bits and pieces like the timing cover and some other stuff I just cant think of right now as its late and Im still working away.
Another thought on VVT is you wont need such a big stall.
All in all I supose it really depends on your goals for the car and how you want to use it? Street strip? Or track machine? or just cruisin and bruisin? Either of the first two and I'd go for cam one above. For a cruiser VVT might be a btter way to fly. One downside though it adds a whole new dimension to tuning.
you will not be retaining VVT with that cam. If its an AFM motor as well, you will need to ditch that and purchase a few lifters. If its strictly VVT, which mine was, I got all the supporting parts for the swap from texas speed as well, they will be able to sell you the cam gear and hardward you need, and perhaps the timing cover as well, not certain there, I already had one.

251/259 660/663 111LSA, LS3 Stg 2.5 Heads milled to 68cc, 1-7/8's LT's,TSP TD's, M6, 12-Bolt 4:10's.... I made 527/475 with a stock unported L76 intake with a TSP 92mm Ported TB. This isn't the final tune on my motor either, but from 3500 on up it screams it's ******* ***** off an i raced a trans am that went 10.80 @ 128 last friday at GateWay in illinois. We went from a 45-Roll an i put just a hair over 4 cars on him it was awesome for sure so i know when it gets the new intake & TB it'll run even better should pick up more of a peak number an lose a little bottom end, but it's gonna run great with the final tune and some juice.

Anyways....It will have VVT, you need to determine if it has AFM or not. You can tell by looking at the valley pan beneath the intake. If its smooth you do not have AFM, if it looks like a maze you do have AFM and it must be removed.
Keep the VVT. It awesome new technology that people have tried to attain since the 60s and 70s and now that its available people are ignorant and simply remove it.
Comp/Texas Speed have VVT cams for your engine and they made +70hp with no torque losses! That's because of VVT!!!!!! Its not possible to gain 70hp with a cam swap and not loose any torque with a standard cam. IIRC is was an 07 Escalade engine all stock except headers. They added a cam, springs, and phaser limiter.
