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!

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

Just got a 2011 1500 5.3 this is perfect

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

Ive been looking for a video like this for weeks

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

[luisjr]

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

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

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

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

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?

[ashtenhungerford]

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

[CaptainAries]

getting a 5.3 avalanche 4x4 and plan on getting some basic bolt ons with a k&n intake in due time

[skin]

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

[coletongossett]

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

[HillcrestClan]

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