My trucks going in for open heart surgery in a month. DOD delete, tsp stage 2 L83/5.3 cam in my L86/6.2. I eventually would love to put a blower on it. I drive the truck frequently and don’t want to do too big of a cam where I’ll have to change my torque converter. Will I get away with a L83 stage 3 cam with my stock converter or should I stick to the stage 2. Specs are 5.3L Stage 2 Camshaft w/ +32% Fuel Lobe: 218/226, 635", 113 LSA, 109 ICL

 

All my mods will be intake, portable TB, (hopefully have my heads ported when it goes in for dod delete and cam) LT4 injectors, 1-7/8 long tube hears, off-road y-pipe. I’ll have a 3.5” electric cut out followed by stock exhaust for now. 
 

Trucks reverse level and blocks removed. 22x12 -51 285/35r22 no trimming or cutting

That's kinda on the edge for size, likely would be okay.

 

The 218/226 would be large for a 5.3 in my opinion on a stock converter, usually a 212/218 is about the biggest people go on a stock converter. The added cubic inches of the 6.2 should make it alright.

 

You also have an 8 speed so the drop in rpm between shifts is less than the 6 speed, so it helps to stay higher in the rpm.

I ended up changing it up for the vvt-2 231/235 .645/.635 116 LSA +32% fuel lobe. I can’t justify doing that much work and end up regretting it by not being aggressive enough. With the stock converter I’ve been hearing it’s less noticeable with it wanting to push through the breaks/stall on the 8-speed trans.

It's not that it will push through or stall but it's going to have nothing down low. The idea of the higher stall converter is to like a light switch snap the rpm in the correct range for that camshaft as well as not allowing the rpms to fall a lot during gear changes.

 

That's a big camshaft for a stock stall and I'd suggest getting a new converter.

Probably a 2500-2800rpm stall. You can contact a torque converter company and tell them the mods you are doing and they will help spec a stall converter.

      I have a 2021 6.2 Chevy Silverado, and just did a muffler and flapper delete. Sounds amazing but is way to loud on the highway and drones way too much for me. I am wanting to put a muffler back on but I want one that is as loud as I can get with no drone. I was looking at the Flowmaster 50 Delta Flow, the 40 series delta flow, or a Magnaflow 22 inch muffler... I am wondering the pros and cons of all of these, if they drone, and how loud they really are. I have watched a bunch of Youtube videos on them and they just don't do a justice for how loud the drone is. If you guys have any other suggestions for what to put on there I am open! Thank you!

      Okay guys I bought this truck from a dealership in September. It was used and I got a 30 Day warranty. After the 30 day period, this is what’s happening. I got in my truck and noticed a rough idle. My truck would shake and out of no where the check engine light starts flashing and my traction control light comes on. I took it to my buddies and we got a P0308 Misfire Detected Cylinder 8. So I did some research.. I also had a code which was P219B. Air/fuel mixture ratio. 
       
      I changed the spark plugs.. didn’t work. I moved coil packs.. the misfire didn’t move. So we watched Live data on the scanner and injector 7 was acting up. So we replaced all the injectors on that side and this truck is still missing.. I’ve ran seafoam through it and cleaned the throttle body and MAS.  My buddy things I have a valve issue or something wrong with the cylinder…
       
      there is no AFM deleted or anything of that sort. The truck has worked flawlessly until now. 135,000 miles on it. The rocker arms all
      looked great.
       
      please someone give me something to try. I just want my truck fixed lol.  
       
      posting a link below of what it’s doing…

      Got a 07 Silverado 1500 classic crew cab with the short bed 5.8ft. Need to replace my bed but having trouble finding another short bed. 
       
      does anyone know if I could put the regular 6ft bed on and will the wheel wheel/fuel filler neck, and bolts line up? 
       
      thank you

      "Opinion ‘Car Talk’ host:
      Independent auto shops deserve the right to repair your car
      September 28, 2022 at 7:00 a.m. EDT
      (Washington Post staff illustration; images by iStock) Ray Magliozzi is one half of NPR’s show “Car Talk,” a longtime independent repair-shop owner, a Dear Car Talk columnist and a car reviewer on CarTalk.com.
      When your car breaks, what do you do? Okay, after you utter a certain word? You have to decide where to take the car to get it fixed, right?
      You really have two choices. You can go to the dealership or an independent repair shop. However, some car manufacturers don’t want to share key information for diagnosing and fixing cars with independent shops — and that’s something that’s not only bad for repair shops but also bad for you.
      As a radio host who has advised thousands on their car problems and as an independent shop owner myself, I know all too well that car owners benefit when they have more choices. Congress is considering a national “right-to-repair” law, and lawmakers need to pass it to protect your rights as a consumer.

      Back in the old days, when people were still switching over from traveling by mastodon, you repaired cars with your eyes, ears, nose and hands — and, if you were desperate, a Chilton repair manual. Now, you often repair a car by first plugging a computer into the on-board-diagnostics port and seeing what the computer tells you is broken.
      So, what’s the problem? Carmakers and their dealerships want to maintain control of modern diagnostic tools, which forces customers to come to them for repairs. Even though independents are willing to pay to license these tools, dealers see an advantage in exclusivity.
      Dealerships have always had certain advantages. They have better coffee in their waiting rooms. Heck, they have waiting rooms. They have clean restrooms that don’t double as auxiliary air-filter storage. They also work on your particular make of car all day, every day. So they might be familiar with an oddball problem because they’ve worked on 4,000 Camrys.

      Independent shops are small businesses, run by individuals — some of whom are terrific people and mechanics and some of whom will blame your car troubles on demonic possession and give you essential oils to fix it.
      But independent shops have their own advantage: price. Their labor and parts costs are usually much lower — hey, who do you think is ultimately paying for the dealerships’ coffee and fancy couches? Some research has found that dealers, on average, charged as much as 20 percent more than independent shops for the same repairs.
      This article was featured in the Opinions A.M. newsletter. Sign up here for a digest of opinions in your inbox six days a week.
      There’s also the matter of distance. Not every town in the United States has a stop light, let alone a dealership for every car brand. There are 16,752 franchised car dealers in the United States, according to the National Automobile Dealers Association, but there are nearly 240,000 repair shops — meaning that for a lot of people, an independent shop is the only nearby option.

      At Car Talk, there are times we’ll strongly recommend an independent shop for standard work like brakes, shocks, the engine and regular service. And there are times we’ll recommend going to the dealership, like when you have a particularly rare problem that might be unique to your make and model. But at the end of the day, you should take your car to the dealer to be fixed because you want to not because dealers have hoarded all the key information.
      Beyond the information needed to diagnose and fix your car, dealerships also want to maintain control of your car’s telematics. What are telematics? Well, now that everything is connected to the internet, your car can notify your dealer when your car needs an oil change or has a blown sensor. Using the software they’re denying to independent shops, the dealer can then diagnose the trouble code, call you and schedule a repair. Most modern cars already have this ability.
      Car manufacturers point to the importance of keeping your car’s data safe — including your location, say — as a reason to deny independent shops access to these tools and codes. They are right about the need for data security, but part of privacy is that you should be the one to decide who has access to your data.
      Story continues below advertisement
       
      At least 17 states have laws on the books stating that your vehicle’s data belongs to you. Many independent repair shops will need to invest in tools to keep customer data secure, but just because they’ll need to invest doesn’t mean they can’t compete with dealers. Lack of choice — and competition — is never good for the consumer.
      So consumer groups and independent shops are promoting what they call right-to-repair legislation, guaranteeing consumers more choice by requiring automakers to license their data with independent repair shops. The voters in my fair state of Massachusetts approved just such a law in 2020. In 2021, 27 states introduced or passed similar legislation. Beyond those state laws, there’s a national push to protect consumers and independent shops. H.R. 6570, a national right-to-repair bill, has been sitting with the House Energy and Commerce Committee for months.
      My Car Talk colleagues and I know not everyone will support right-to-repair laws. Dealerships won’t like the level playing field. Mechanics might not like how much work they’ll actually have to do. Still, this is an issue everyone else can get behind. If you own something, you should be able to choose where to repair it.
