No I had Pray Performance port it.  He is very well known on the 6th gen Camaros and will port anything.  He is also tuning mine as well.

did you  cfm flow a set of stock heads before throwing the wallet at the intake manifold and new TB.  i doubt the stock 5.3 heads out flow the 6.2 manifold and 6.2 tb...

Who are you asking??   Mine is a 6.2 so I had my stock intake manifold ported and added a ported 95mm tb as well.

If you're keeping your truck N/A go for it. If you're going turbo don't bother and if you're getting SC you'll want a bigger TB. Other than that I wouldn't bother. 

 

If you want a N/A Intake and TB combo get the Atomic with 102 Nick Williams or 103 Lingenfelter.

The msd atomic intake manifold will make more hp and tq from 5500 on.  Not good in a truck (I tried it).  The truck intake vs ported atomic was down 60wtq and 20whp peak to peak. At 4500 it was down 50wtq and 40whp.  From 3000-5500 the truck intake manifold (unported) beats the msd ported. My advise would be to port the stock truck intake and add a 95mm tb.  PRAY is the only 1 I know of doing it.  Ports the throat to accept the 95 without an adapter.  My truck hasn't been back on the dyno since I put the truck intake back on.  There are many FBO L86s making 420/460 or more with stock unported intake and tb on e85 at the wheels which is advertised at the flywheel from GM. On the LT1 in the 6th gen Camaro PRAY's ported intake and ported stock tb are worth 17-20hp from back to back testing he did.  Check out his FB page or Camaro6 forums.

I don’t need it. My L86 intake is ported. I also have a potted 95mm Tb. I’m forced induction too. I was just saying to the guy asking the questions that their ARE intakes that fit the bolt patterns.  
 

also, Gwatney does the porting service.

Yes Gwatney does port them and also takes all the structure out of the intake manifold.  Then they epoxy a sheet of aluminum to the floor of the intake.  Nowhere on their site does it mention they port it to work with the 95 either.  Holley's high ram is killing it on the Camaro and someone on performancetrucks put one on their truck (cant remember if it was a L83 or L86).  LME makes intakes out of billet for $4500 or so.  There are some options available now.

I didn’t say Gwatney ports the TB. I just stated I had one too. It does wonders for my set up. 
 

I thought about the high ram from Holley. It just does t make sense for me. I don’t race my truck. Just an enthusiast with a hankering for power.

Just wanted to let you guys know that we also make a 95mm, actually 100mm effective at WOT after the rework, they come (included in price) with an Adapter Kit specifically for your manifold, stock manifold Adapter, MSD manifold adapter, or we'll also match your own ported stock manifold.

 

Add our controller to it, and you'll have a total solution to the slow response.

Okay so I am wanting to go from and l83 TB & Manifold To a l86. Other than just getting the gaskets for both things what else am I going to need to purchase complete the swap.

 while your at it, dont forget to yank the stock airbox , carefully with a prybar lift under the box til it pops up, and then remove the muffler restrictor panel before the airfilterl , it unclips right out.. then push the box back in place, enjoy the growl....

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou

      Is it an optical illusion in the pic or is the truck really squatting that much horribly?

      It's Been a Long Time...

      My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
