Best Performance Mods For 5.3 Chevy Vortec 

Start Your Performance Truck Build! bit.ly/3qujUXL

My buddy has an 04 Silverado that was in a rollover, he sawed off the tops of the cab and made a convertible to go ripping through the woods on. That day we rode around in it was the day I swore that I’d get my hands on a Chevy for my own, because he was beating the ever-loving sh*t out of it and it never skipped a beat.

I drive an 03 Silverado and for the last year I’ve been driving it with a blown head gasket so when the man says bullet proof believe it 😂

Just got me an 01 2500HD with a 6.0L and I’m excited to start getting some power out of that thing! Thanks for the video!

Just got a 2011 1500 5.3 this is perfect

This video was meant for me, I just recently got my first vehicle which just so happens to be a 1999 Chevy Silverado 2500 gas, 5.3 v8 ls engine. This was an amazing, very informational video, thank you!

Surprised these guys never talked about stall converters, gearing and intake manifolds, 5.3's really wake up in trucks with a stall and really short gears like 4.56's or 4.88's and I find it to be very pointless to cam any LS without an upgraded intake manifold too extend the rev range and more power obviously

Ive been looking for a video like this for weeks

I tow big sheds with my half ton chevy 2010 and 2004. Still going.

I’m not proud to admit that I had a oil cooler gasket leaking by the oil filter and had a bunch of insane crap happening in my life and I stopped checking my oil level for a long time, almost like it was something that didn’t need to be done anymore. Obviously the first owner I bought my 2011 Chevy Silverado 5.3 Z71 must have made keeping the oil level at the correct level something he did religiously. Because my low oil level sensor doesn’t work probably because it never had to move the entire time he owned it . I had about a 173 thousand miles on my truck when while on the interstate my oil pressure went to 0 . With no extra oil in my truck anywhere and just have given my wife the debit card . I had no way to by oil. I had about 12 miles to go before reaching home. I decided to just push it all the way home doing my best to not get stopped at any red light, stop sign or in traffic. Got home and it was bone dry. Got oil and filled it up and about 75 thousand miles later still runs like a beast with absolutely 0 damage of any kind that I can find and remember it’s a AFM ENGINE

The very best mod for a 5.3 14 and newer is a tune from Trifecta, trust me!! Awesome 👍👍

I just got my first broke lifter assessing damge tommorow looking into this video since im already in the enigine

What about the 5.7? I’ve got edelbrock heads, comp cam and new rods going in mine plus a set of hooker headers and a three inch quad exhaust

Thanks!

I have a 2011 chevy suburban 1500 lt which carries a 5.3l LMG. I'm trying to figure out what is the best way to get 400hp and 420tq at the flywheel. I'm in the process of installing a 3.42 gear set.... any recommendations?

That's good to here might put one in my 62 Chevy instead of the engine it has now

for N/A how much do you think for everything besides adding boost

Got a flowmaster 40 series on my 2003 tahoe, need to run the exhaust over the axel and out at a 45 on both sides

Thank you

I gave you a like cause u mentioned Fast and Furious movie 👍

what are you thoughts on getting a 5.3L chevy avalanche staight piped duals into y pipe 2.25 tail pipes into 5 inch tips

Don’t forget to either upgrade or build your 4l60e or 4l80 swap it 😂 I’m on my third tranny

Owned one for years, they should make tank armor out of this engine

Do this video for the 6.6!

Wow your videos are awesome

Why would my 5.3 Z71 rado pop a knock out of thin air right after i filled my tank it happened and to be honest now that I think about it my gas tank wouldn't take no more then 2 notches past 3 quarters of a tank... Should any be able to help me I just bought this truck yesterday and it never sounded like a 12v diesel till last night I'm hoping it's just bad gas and not total engine failure

Yall should do this video but for the 5.0 coyote

I want more power to not drop to 35 mph on towing up a mountain. What will help ? Got a 3.5, with a 4l60e. Cheap,? Have a big trans cooler. 04. Got rear towing shock/springs. Which helps. Engine and trans ... help. Only has 102000 on it. Trailers sometimes at max ,but only going 200 miles. I don't break 3rd till the Arbuckle mountains for around 40 miles. .wishing had the bigger trans.. hard to find

Throttle body spacer to compliment all others listed.

I am definitely that guy🙃 2:40 But not for long I’m about to do a fender exit

Can removing everything factory and allow more air ratio better for engine?

i have a 03 cateye with a 5.3 LS and a cherry bomb muffler, i pretty much have everything in this video except a turbo and nas

Anyone got any suggestions for long tube headers specific brand and does it really make a difference 🤔🤔🤔 Thanks In Advance💯💯💯

I wanna make my 5.3 Chevy avalanche vortex motor off road u should make a video on that never seen a Chevy off road I wanna do it to mine it’s just so hard to find out where to start

I've got a 08 with AFM deleted, FiTech intake manifold, 102mm throttle body, cold air intake, 50lb/hr injectors, stage 3cam, forged pistons, a 150shot of nitrous

👋99 Silverado. Was going to just buy a performance upgrade (460hp) engine for it, older buddy of mine told me he’d help me just build one, and for half the cost. So I’m gonna head to a junkyard and get a hood 5.3 block, have it machined, and build it up, learn on it so in the future when things break because they will, I won’t have to send it to a friend to be fixed. That and I don’t have to drop 5 grand straight out, I can take my time and drop yk 500 here and 200 there

Got a 2012 silverado 5.3 stage 2 tsp cam, long tube headers,x pipe,3:73 gears, on e85. Not sure what i should do to it next any ideas?

U should do this for the gm 6.0 I never see videos on the engine and wonder things I should be doing to my 2500hd

Probably need a better drive line too. I was told my 08 silverado stock driveline is crap. And will fail if I try to add more power then I have..

I ran my 5.3 on no oil. that didn’t end as well as it did for grant tho😅

Did they make any 2012 3/4 ton with 5.3 engines?

What about Go-Fast stickers?

I have a 2000 Z71 1500 that is my pride and joy. I'm pulling the engine out to freshen it up and make some repairs. Is there a realistic way for me to make a decent amount of power and still be reliable enough to drive cross country?

Do a video for a 5.7 Vortex engine please 🙏

Thanks just bought a 2001 silverado off a neighbor who had abandoned it in his driveway needs a lil TLC but alot cheaper than a new one with the money I saved i want to hook up the engine what should I start with 1st high mileage but runs solid?

What manifatture u recamend on header and manifold

I have a cold air intake and a smaller muffler on my silverado. I felt some differences after doing those modifications, but I feel like it's still lacking power. Will I need a tuner as well? If so, what do you recommend?

I just thought of a sick build. 96 Tahoe 2door with the 5.3. Lowered. Big wheels. Black out

Hell! Even the 4.3 vortec was a hella engine even stock.

Haven't watched vid. But top 3 would be cam, 3000 stall converter, regear and of course a dyno tune

what about 5.7L upgrades? are the about the same?

Damn that Banker comment came at my throat… granted I’m gonna straight pipe it to side exit but for now, I am that guy😢

Dustin you already know I am that guy lmao, mufflers been gone since like week 2 lol

Long tube headers with cold air intake on a 5.3 gmc Sierra. What size cam would you recommend

What can I do for a basic horsepower on my 5.3 Chevy Tahoe LS for hauling like camper trailers car haulers stuff like that and a daily driver but I really do want more horsepower without the NOS and turbo or supercharger even though supercharger is an idea

Had a 5.3 sold it running like a champ with 225,000 miles and had a lq4 6.0 sold that with 245,000 still running idk why most folks have so many issues these engines are as good as a 4 bolt main otherwise its lsx or a good old duramax now that's a ride stock theyll walk the dog on a pullin sled point 9f my story if u ain't got any of these motors your wasting money 🤣🤣🤣

Finally!!

I recently got a beater silverado I want to build this one up But I really got no idea where to start can anyone help ?

My dad and I are building a 55 Belair with a 5.3 LS1

Now do this video for the 6.0 please.

was the beginning from waynes world? been so long since I seen it im not sure.

I have '12 Gen IV. I'm hoping keeping clean oil in it and a Range ODBII delete will keep it from dropping a lifter. The first mod should be AFM delete.

Gotta stage 2 cam in my 08 woth 8” kit and 35s and it’ll get down with the get down 😂

How easy is it for a rook to install new headers on a 2018 Silverado 1500 LTZ? Mine is a 5.3L V8 as well.

Let’s us not forget about some fuzzy dice!

Can y’all do one for the 5.7 guys

Most of this also applies to 4.8s and 6.0s

I just bought an 06 silverado with a 5.3 vortec. My first truck for work. Did I make an ok decision? Has around 105k on it. Are they reliable?

Does anyone know if they make turbos for 08 Tahoe's 5.3 vortec engines

what’s the best exhaust system for 07-13 GM 5.3’s

You got sum perty eyes boy……in my best sling blade voice

Oh yea!!

I have a 2008 suburban z71 5.3L. is that an LS?

Could Custom Offset do the f150 5.0?? I’d love to see that!

My 5.3 has ticking!😁

The 4.8 with no muffler sounds great just don’t cut the cat off and you’re fine

I’m putting one in my Porsche

Do these also apply to a 4.8 v8 gm motor?

Day 3 of saying Dustin has pretty eyes until it's mentioned in a video

I got a friend that put a cam, cold air, and exhaust in his 5.3. He ran a 11.5 in the quarter.

What about the L86 6.2?

What do you do about transmission problems after ????

Literally just cut my muffler off today!!!...I'm that guy lmao 🤣 🤣 🤣 🤣

Hey I made the video!!!

Long tube headers or short tube headers?

Do this for the 5.7 hemi

You talk about adding power but forget to mention their transmissions are made of glass. The 4l60E trans is fine as long as you don’t tow, abuse, or add any extra power to it.

Cam shaft cost like $3000 installed and tuned for like 100 hp that’s worth it.

2:40 🙋🏼‍♂️I’m that guy

The first mod should be an AFM delete. 🙊. Now, if you got cash that's when you can also go ahead and beef up your Cam shaft and other parts.

any opinions on tuning a 5.3 to delete the AFM?

Does all this go for a LT vortec 5.3 too??

I looked with pleasure.

They were great, until they added AFM to the 5.3. Took good care of that truck and it was great to 90k, then I couldn't keep the lifters from dropping.

Should hit on the 4.8 sometime

Go check on d gas racing they're making crazy power with 5.3s

Pretty sure Dustin is a Viking

What kinda truck is in the thumbnail?

I have a 2007 Z71 1500 classic. The motor is a gimp. Wants to kill at idle but will not. 165k. Anything anyone??

0n the 5:3 liter
