Yes, definitely an old post but the project is still underway. We ran into some serious time delays with Covid, and the body shop getting everything completed but that is now behind us. Then we ran into some problems with the engine builder ordering the wrong supercharger., that Delete us a couple more months. The engine has been pulled and I believe it will go back into the shop in the next couple weeks for the install. Still shooting for 850 wheel horsepower to start then doing secondary fuel injection and bumping that closer to 1000 or 1200 hp. After that, we will try to get it into a couple magazines and we are currently looking for sponsors to get it into this years SEMA show/convention.

It’s one of my never ending projects…. Still in the original body shop. There hopefully is a light at the end of the tunnel, l don’t want to jinx it but it looks close to completion. Next step, off to the performance shop for the engine swap.

I’m a little hesitant to use the edge or Banks system. I don’t necessarily like how they interact with the ECM changing parameters from what the ECM is really l telling the truck. I prefer to have a fully tuned ECM that I can swap out. I plan on upgrading to 37 inch for 38 inch tires, I just want to compensate for the power loss in the gearing change. A little extra power it’s not bad either. Not looking to drag race but I do occasionally tow 10 to 15,000 pound loads.

For those of you who are looking for the same answers. It looks like the front axles on our trucks are sealed. There is no re-gearing option for our trucks for four-wheel-drive trucks. Only 2 Wheel Dr.

Anyone running emission compliant ECM tuning? If so which tuner/company did you go with and how happy are you with them?

Sorry diesel.

Order placed January 25th. GM just picked up the order up Friday March 4th. Now the wait begins.

I have them on my current 2022 high country and they are on the new high country I have in order. I think they are prioritizing them on the higher trim models.

You can 100% tune your truck. It’s not cheap but it can be done, $1000 to unlock the ECM. That said this discussion is more about what I need to do wheels and suspension wise, not performance.

Hey guys I have a couple questions for you. I am looking to run 38’s on a 2022 3500. I’d like to use a 3/2 level kit, not a full on suspension lift. I’d also like to use the stock high country wheels if possible to keep it looking at least fairly stock. I realize it will be a little bit of trimming necessary and most likely a mudflap delete. 1. Do you think that wheel spacers will be necessary? 2. I would probably want to do a regear to try and maintain the factory final gearing. What ratio differentials would I have to get to get back to stock?

I wonder if the 2500 CCSB tank would fit in the 1500. I believe it’s 35/36 gallons.

Man this project is taking longer than expected. There’s a light at the end of the tunnel though. The truck is almost out of the shop that is doing the short bed conversion and custom paint. The one off wheels are in. The engine is finally done!!!! Still moving slower than I expected but it’s progressing.

Anyone know what power the stock 5.3l is putting down with the whipple? I’m thinking of taking the 5.3 out of my 2020 build and drop it in a Jeep JK.

Looking good! Give us a full report once you get her on the road.

Stuck with wet sump. 1. Less things to fail. 2. No issue with ground clearance. 3. I’ts not going to be a road course truck.

Update: truck is coming back to the builder/shop from the suspension shop. Did a 4/6 drop, traction bars and driveshaft loop by VAS Specialties https://www.vasfab.com/ The engine has been my biggest headache. Apparently Edlebrock is moving out of California and is in mid move. I’ve been calling for 6+ weeks to order the engine and have gotten horrible customer service. I finally spoke to a sales manager 2 weeks ago, they do not have any blocks in stock and he doesn’t even know where they could produce the engine as their Cali facility is closed and haven’t moved into their new one. He promised me a call back 2 weeks ago..... (so did the other 6 people I’ve talked to there, still waiting). I ordered an engine from Late Model Engines in Houston. https://latemodelengines.com/They produce some serious engines for some of the top names in the business. Pricing is significantly more than Edlebrock BUT customer service it top tier as well as communication and individual attention. Sticking with a 416ci motor and an Edlebrock 2650 supercharger. It will produce 900-1000hp to start, I’m having them mill/port the SC to add secondary port injection later, the block is good to 1400hp. Hopefully the truck will be out of paint in the next 3 weeks. Custom 1 off wheels are still 8-10 weeks out and the engine is around 8-9 weeks. That’ll give us time to have a level 4 trans built and installed by Circle D. https://www.circledtrans.com/6l80-level-4

I think I read the carbon pro option only saves 60lbs of weight. It was t worth it to me.

I have a guy that works for me, he has to be late 50’s. He has the train horns installed on his truck. He thinks it’s the coolest thing and sooooo funny, we just think he’s a doushebah.

For a 2 piece design just hiinge the section of at the top not the side.

Great, I didn’t know this existed but now I need it.

Here are all their products for current generation Sierra/Silverado’s. Scroll down to their pro series kits. They will give you the capacity of a 2500 series truck. https://www.hellwigproducts.com/products/search-by-vehicle/?Year1=2020&Make=GMC&Model=Sierra+1500 It is a progressive setup when you are unloaded it rides like a stock vehicle. It can also be tuned by tightening the U bolts that tie the springs together to give you a stiffer starting point.

I used Helwig helper springs on my 2500 and it made a HUUUGE difference. Daily drives the same and I’ve towed 12,000 lbs with over 2000lbs in the bed with minimal sag. Much simpler than an airbag set up with less to fail.

I have an ‘05 duranax that I tuned +100hp and +200lbs of torque. I did it around 30k miles. I now have north of 250k miles and not a single problem with the engine or drivetrain.

Too much bitching from all sides. I’m out of this thread.
