we're building the WORLD'S FASTEST stock bottom end 8.1

we're on a quest to make the world's fastest stock bottom end (piston, rod, crank, block) 8.1 vortec powered silverado, and later this summer we're going to run a 9 second quarter pass with UglyTruck, but do do so, we need to make a few small changes in the induction and suspension department. Today, we're doing just that, all while improving the looks.

[@MattsOffRoadRecovery]

When you said “it’s not a claw hammer….” That really hurt 😢

[@JohnDoe-en9ch]

Coming from a guy that considers a rock an essential piece of recovery equipment! 😂

Always good to see the truck that started it all, and has inspired others to look into working on the 8.1.

[@paddywagon5_0]

6:26 I love having 2 different hole options. 😂

[@blahblah4125]

I've been watching your channel for a while. I watch POWERNATION as well and saw you in an episode back in 2009, you definitely have expert level fabrication chops. Thanks for what you do, your channel is very enjoyable for a car guy like me.

[@markcraig2512]

I like how you keep your work area clean. We’re mechanics not pigs. Also you always go the extra mile to make everything strong and safe.

[@beausmith3900]

I'm really liking the new wheels on this lt...

[@V8RJIM]

Lots of great info. That vise flopping around would drive me crazy. A good solid bench vise attached to a solid work bench makes life easier.

[@aslacker]

Nice job on those brackets for throttle !

[@ricmorris6789]

found something unique to your videos. Besides all the fabrication & tech info, I now listen to hear what song is playing in the background! Good choice of shop music!

[@WilliamJernigan-qp1fn]

My first dad memory was taking a hacksaw and making a inner tie rod tool and welding a pipe between the socket and ratchet

[@J-RocksCustoms]

Brake rotor direction usually goes by the direction of the veins. If veins are straight up and down it really don’t matter which direction you put them.

[@amazeddude1780]

Not many KZbinrs would know about the cave paintings near Montignac, France. Four teenagers discover those prehistoric cave paintings when they were following their dog down into a cavern.

[@ZippoVarga]

I hope you don't mind Lawrence, but I've been living vicariously through your videos. So keep it up buddy! Cheers! Zip~

[@goodson77784]

Thanks to you I'm swapping the engine in my 1500 burb to an 8.1

[@patrickmoran7830]

I love that you are keeping this project going.

[@justinkramer3653]

Love the work on the throttle brackets! Absolutely professional.. its all about the small details

[@kiretheyoutuber6535]

1:22 I think that style of rotor scoops air inwards towards the rotor with the direction the veins are going, which it why the manufacturer tells you to go that direction.

[@mikeo5668]

Can't wait to see it run down the strip

[@brandonhackley7067]

Love the build

[@bobmerlo9198]

I still have that same hacksaw in my toolbox Great tool !

[@teaguegearhart9851]

I am with ya. 9 here we come.

[@That_Dyna_Guy]

Loving the fabrication LT! A tip, if you want to mimic the cast look/texture of the manifold on the tab you welded on, you can hit the tab and weld with a needle scaler

[@Boogie1967]

Matt might send you straps after seeing you lift the box off Great video

[@bm9860sts]

Love following along. Nice work LT

[@mahdialsenussi3066]

You WORK always amazing 🔥👍🏼

[@chriswise1232]

I used a claw hammer for years, back when drums were more plentiful. The claw can yank or pry them off real quick.

[@wxmt95]

thin mints are my fav! love the 8.1 content

[@4BillC]

For what it's worth I put my rotors on the same way. Left or right side really only matter if the vains inside the rotor are curved, most are straight making air flow through the rotor the same no matter what direction it spins.

[@GreaseMonkeyVIP]

have you ever thought of cutting the bedside internal braces and changing them to all thread with a sleeve that spins out to get more clearance on the tires? I had a friend with an OBS who could get around an inch and a quarter to inch and 3/4 before causing problems and still look barely stock but had a lot of clearance for tires if you are a serious street hound!

[@ericguggenbiller7266]

You may wanna think about adding a set of either Funkhouser brackets or a set of MAK gap bracket on the leaf spring it’ll help with your bar angle also

[@LawrenceTolman]

That is a good idea, I've been thinking about trying something like that for the 4x4 so I should probably grab a set for UGT also

[@Mr572u]

I hope you recheck your pinion angle after that!👍

[@tylerangieslayton7455]

👍🏼Glad to see her sitting at a more level height, without the Carolina squat😅

[@robertsmith7580]

Awesome video

[@Bella-b5u9i]

Your videos always stand out for their quality and originality. Thank you for your contribution!👾🕊🥒

[@bluecollarhotrods9781]

Just curious if what you did changed the shock angle/throw at all? Doesn't seem like it's enough to matter, but I do recall when you order shocks/brackets from Atomic, Richard has you specify certain measurements pertaining to ride height/fender lip to ground relation.

[@tyler6602]

hell yea

[@MIUBHI007]

Doesn’t matter which way the holes and slots are oriented, only the veins on the inside. If the veins are straight, then they are bi-directional and can be put on either way.

[@jsilver919]

Lt, you are going to drive the price of all junkyard 8.1s out there 🤣

[@actschp1]

Bandsaw and a 4'x4' plasma table. Can you imagine how much faster some of your fab work would be?

[@HooligansMx]

Needs a tubular front end with long travels!

[@jefflamb5343]

Not sure if you have exhaust backpressure (EMAP) sensors on ugly truck or your 4x4 drag truck build, but it would be good to install this type of sensor on both so you can quickly and easily determine how restrictive the hot sides of your turbos are on these big engines.

[@johanwallqvist646]

Hi LT! Do you think one 4" pipe is enough for the new Hp? Maybe time for a Cut-out? Great channel🤩

[@tommoon2700]

Heartbeat of america 💪

[@JacobBennett45]

Diaper or pan under it? Might be a good idea if we’re pushing the limits of the bottom end

[@JohnBoyBuilds]

Next project i wanna see you do a turbo 4200 atlas i6 with in a elcamino or 4th gen camaro

[@stupidlegos6485]

That’s something that’s up @nivlac57 KZbin channel. He does lots of atlas engine builds and customs swaps.

[@scottg391]

When you get into the 9's, give that truck a paint job. It deserves it....

[@KTMGREG55]

No way it needs and Ugly Wrap 👌😂🤣

[@scottg391]

@@KTMGREG55 It deserves at least an Earl Scheib 29.95 paint job....No ups, no extras, They'll even paint the exhaust pipes free of charge....

[@joshuaelizabethfoster6276]

Larry at raylar said he's making a stainless steel head gasket. I almost port matched the head gasket to the block/head water jacket holes. The holes are like 1/8" on the gasket and block most of the passage...can't understand why the jacket ports are so big but the gasket holes are so small? The seal goes around the whole area with tiny holes? Kinda thought Larry might have fixed that on his stainless ones. Me thinks that's the difference between the stock 340hp and stock 320hp numbers. Also with right love the 8.1l is around 650/700hp NA and runs a very safe 1000hp with 5-7lbs of boost on top of that.

[@rocks-if6uh]

Hey LT i have come across a performance alternative fuel company that i found a bit interesting especially since they may or may not have prevy to test certain power plants that are not shall we say supposed to even exists in this part of the hemisphere. You may already have knowledge of for mentioned group but i might stop at your shop to say hello. Oh and im thinking a 9 second MORRVAIR would look great doing a recovery dragging the competition at the same time.😂

[@carbonfiber8071]

Will that tab on the MAP sensor transfer heat to it? Could you make it from phenolic material?

[@GhostSniper67]

I wish I was close to you, I need work done to my SUV and I wish you could do it.

[@Metalwolf765]

Paint that raylar black so it looks less “race” than the fast truck!

Woo Hoo!!

[@InnocentMiscreant]

It was making 800 before the cam upgrade as a 100% stock engine with these upgrades. I'd be hoping to see maybe 1200 wheel horsepower

[@carbonfiber8071]

Lead, arsenic and glyphosate just found in ALL the girl scout cookies tested. It was just in the news.

It's ok they indentify as carrots.

[@Saudicitizen]

I wonder if i made empty intake manifold how it's will perform?

[@aaronfields57]

I want to do a similar build with an 8.1 and turbo but in a c10 or an El Camino Make it consistent and comfy enough for drag and drive

[@cameronwilliams8035]

@3:08 Is that a nail in the tire?

[@scottlance2404]

I saw that also!! lol. Inside tread on drivers rear tire!! Haha.

[@BigfootMoto98]

I want to do a cammed 8.1 in a manual C5 so bad

[@timothycarey3883]

The ls1 in a c5 is faster. A 6.0 or 6.2 would be more fun.

[@GreaseMonkeyVIP]

hey the reason Matt is used to a Clawhammer is because he was a roofer for so many dang years before he became a professional on KZbin lol being a roofer you use a dang Clawhammer for everything lol

[@mikeoverby2232]

Found a Mahle 2003 8.1 head gasket kit for $366.49 if that helps. I know you’re super particular and pretty much OCD when you build your engines which is a good thing. Just thought I’d help if you want any more information hit me up. Good luck with the build. I enjoy your videos a lot.

[@timothycarey3883]

Man thats insane for headgaskets, glad i dont plan on building an 8.1.

[@XLTJeff]

would Matt's Off-Road Wrecker be better off with Tri-Y Headers instead of the Long Tube Headers that he is putting on now, and doesn't Tri-Y Headers take up less space generally 🤔

[@johndcramblit3045]

Taking a heavy beast like that into the 9's, shouldn't you be installing at least 6 piston calipers on the front?

[@jeremycook9852]

What happened with the 4X4 drag truck build? Seems like we haven't seen it in years.

[@LawrenceTolman]

Still have it, just waiting to gather a few more parts then we’ll get back on it

[@craigessich611]

LT , do you know of anybody that sells fuel rails since they are Discontinued? Thx

[@LawrenceTolman]

i am not aware of any aftermarket ones out there, i usually buy them second hand

[@TehSwiftly]

I’ve always wondered this but do you actually like matco or was it given to you when you parted ways with the tv series? I know they sponsored the show so I’ve just always been curious.

[@mchristr]

Another LT video? Click! When are you going to fix that left outer bed sheet metal? Now that I've mentioned it, it's going to bug you (sorry 'bout that).

[@JohnDoe-en9ch]

Think about all the locals who bring their cars in for mundane stuff like brakes and oil changes that have no idea they have an accomplished car builder right in their backyard.

[@TrevorDennis100]

I have to say, I would have expected the radial slots in those brake disks to to trail outwards rather than inwards. Centrifugal force will already be trying to dispel water outwards, so why would you counter that force - unless you want water to stay on the disks and pads? I am looking at the outside tread on the tire right after you talk about the brake disk, which has a tread pattern dispelling water away from the tire. Then there are tractor tires (driven wheels) which have a very pronounced tread that pushes mud away from the tire. You brake disk instructions are not making sense to me. Do those disks have internal veins? If so, and I am sure they do, then they should absolutely be scooping air and pumping it into the cavity to cool the disks/rotors. Here you go. This short video says fit them with the slots trailing outwards. kzbin.info/www/bejne/oaOvgKxvZbClrLs

[@KTMGREG55]

Don’t care for the cameraman. I liked how you did it yourself. He’s too slow and don’t like his camera work/angles

Why didn't you use plasma to cut aluminum throttle bracket?
