There's no replacement for displacement man. Most hi-power mods to a naturally aspirated motor come at the expense of street manners. For all the money you spend to coax another 100 horsepower out of the 5.3, you could have just gone with a 6.2 or larger motor.

6.2 has an extra 60 hp and its heavy but yet again I'm just learning I know its a bigger motor u can bore it out blah blah

Spend more time learning and less time asking.

I’ve owned a few blown gas trucks. For the money drivability and longevity couldn’t be happier. My 92 is more radical than that I’ve had it 10 years just maintenance. I bought it off E-bay already done. I expected to have to do a rebuild, hasn’t happened yet. I even run the small pulley sometimes. Do the research. Especially if you’re a do it yourself type. You can do a kit in one weekend. Quicker than going inside the engine with better results.

These trucks are to new and not enough info about reliable parts so yes I'm asking for opinions and sets ups people do and dont like ect. And all .motor will wreck a 5500 lb truck how? I come from the custom frame and suspension world not modifying engines thanks keyboard warriors

FOR YOU INFO therea only 1 local guy boosted pushing 1000 hp with a 16 gmc . So how the **** is 1 guy gunna have all the info if I listen to everything he has we would have the same build.......

another thing I'd like to know is what also needs to be switched I know stock cats need to be replaced with high flow . What other random crap like that needs to be considered

How much 'all motor' do you want?

You have to pick a hp/tq number and set that as the goal. Then you have to decide if your budget will handle it.

Not hard to blow $20 or 30gs screwing around with stuff like this. I'd strongly suggest making damn sure you know exactly what you want, else you're going to blow your budget all to hell.

IMO, you'd be waay better off dropping the 'all motor' idea and just putting a supercharger kit on it. Waaay easier, waaay less screwing around, more reliable and waaay better for the street, towing etc. Less money in the long run as well.......There are a few different supercharger options out there.

Lol at custom frames and suspension world.

you obviously don’t come from the motor building world.

any sort of all-motor build, aka NA build, involves making it breath as much as possible. Cams, heads, exhaust, intake, etc etc etc. They all produce hp by allowing the motor to breath. When you allow a motor to breath it moves the power band to the right. It sacrifices low end hp to make hp up top.

This is great in a sports car, but horrible for a 5500lb truck unless your going high stall race only truck with no streetability. Can you make 800hp NA, sure, but it will ruin the streetability. That is why you don’t see NA build trucks.

Now I’m not talking about bolt on, I’m talking about legit NA builds.

but being a real enthusiast, and not a keyboard warrior, you must already know all this

The LT platform has been taken to it’s limits 100’s of times, you can find this info out on corvette forums and camaro forums. You surely knew that as well.

its looking like na is a waste of time and to expensive a supercharger maybe the route to go for daily driving and less maintenance compared to turbos

I think you mean a L82. never heard of a L85. You might want to change the title.

If you have Flex Fuel then you have a L83.

If you don't have flex fuel and its AFM its a L82

BlancoSilverado, my 17 has the L83 non flex w/afm. Perhaps this is different for other years. I even requested a build sheet from GM to be sure. It states the block is indeed L83. Can you shed some light for me?

Back to the original topic and ask. . . .

I know I've said it in dozens of posts. It is much cheaper, safer and more reliable to just SC your truck. Coming from experience you'll easily save $24,000...

Here are websites I've used for parts and information getting into the GM Gen V platform.

https://www.onallcylinders.com.

This is an awesome site to look at specific engines, their specs and some build suggestions.

https://www.gmpartsdirect.co/auto-parts/2014/gmc/sierra-1500/denali-trim/6-2l-v8-gas-engine

Great for stock parts or some budget friendly upgrades like Injectors, fuel pumps etc.

https://www.carid.com/2014-gmc-sierra-denali-accessories/#spb_exterioraccessories

Great resource for ALL types of parts for ALL types of vehicles.

https://www.jegs.com. and/or https://www.summitracing.com

Perfect for sourcing anything stock or aftermarket. I usually purchase my Oil and Meth (Boost Juice) from here.

https://www.texas-speed.com

pioneers in many GM LS based items. Top or bottom end solutions.

https://gwatneyperformance.com

Great for some really niche solutions such as true drop in piston/rod combos that will bulletproof your Gen V Block.

https://www.briantooleyracing.com

Classic resource for cams and fuel management delete kits.

https://www.rockauto.com/?a=G

rock bottom prices and a good source for replacement parts.

Here are some popular power adder websites:

http://performancefueled.com/trick-performance-turbo-kits/

trick turbo system

https://whipplesuperchargers.com

Whipple SC's

https://treperformance.com

This is the best site I've found for prochargers, upgraded components and price of kits.

I'm sure I've missed things, this should be a great springboard for anyone wanting to look into upgrades.

this is exactly what I wanted thank you very much I knew there was. at least 1 person on this website that actually knew information

Many of us have been around the game long before these direct injected engines. It's just that some may not want to do someones homework for them is all.

This guy will end up doing a CAI and a crappy cat back plus some cheap zero HP parts. Very easy to sniff out a dreamer.
