Our GMT400 Suburban 10.3L Big Block Build Begins! "Uncle George" Will Never Be The Same (632 BBC) 

What 2000s rock song title fits with pulling/installing an engine scenario? 😂 Example: “can you take me higher”….“it’s never too late” )when coolant starts pouring on the floor) etc. Let’s hear some good ones 🤟🏻😂

Get er done! I got turned on to your videos by my late son. During quarantine in 2020, I rented an air bnb with him. I was never a youtuber. But liked Garrett/cleetus, and we followed you I believe during a race week in the LSEcalade. Thanks for the ride.

I honestly love working on these gmt400s some things are tricky but once you learn it you never forget it. They are incredibly simple trucks. And everything bolts together very nicely.

I love it. I'm a huge sucker for OBS Suburbans. I've had a 98 K2500 7.4 and I'm currently 6.0 LS swapping my 98 K1500. This video makes me happy.

I always said that I needed 5 year old sized hands to work on those old 80-90s GM products...! Looks like a Logan world's as well...! Holy cow, I'm jealous too...! Sitting up right under a suburban without lifting it...! Just wow, you've got a hell of a helper...! Not bad on the eyes either...! Very cool, thanks and keep up your awesomeness...!

You guys are awesome together as a team. I have pulled out both SBC and ls motors and I agree the LS motors are a little bit easier but to me both were fun to do can't wait to see the rest of this build great job Mitchell and Logan

I love watching yall, its not high tech stuff that you can't understand, you explain stuff as a real person, real appreciate that👍

its sometimes daunting to get into a 40 minute video. But you had me the entire time! Rough day at the office so its taken 5 hours to catch all 37 mins or so but I wanted to say; listening to your wrap up.. You bring such a fresh perspective to youtube, something that at its core seems so obvious, but something that is NOT the main anymore. its hardly even desired to take something away from what you watch anymore. I hear so many people say now they just want to turn off and watch something (i dont get it) I think its a reason I always find myself coming back watching all your content. Being an LS turbo guy, when i saw this blue whale come in to PFI singing with twins like that, I was instantly hooked. Youve had me ever since. Thanks for taking the drive to CO. Cant say Id be a follower now without. Sorry for the long post!

The Home Improvement reference to Wilson the neighbor who hides his face lol, I still watch that show all the time. Loved it growing up too

Hells yes, please build an "overlanding" burb with a fawking matching canoe!

Hell yeah Mitchell and Logan! This video just made my day. As Mitchell knows I went through my second major colon surgery back two days before Thanksgiving and I've been recovering since...but now the problem is I've been deathly sick since Saturday night and our doctor is worthless and won't see patients if they have fevers or anything like that. Fevers ended Monday night but it ain't getting better. Feels like sinus shit with a lot of abdominal pain and a headache from hell with throwing up. Thank you guys for always knowing when to cheer a guy up! I'm so damn pumped for this build.

Mr Mitchell and Ms Logan or should I say Mr Hood Cleetus and Ms Logan. I've been waiting for this day to come ever since you managed to swindle them at Blue Print to get the engine. Uncle George is gonna be a bona-fide ripper. I'm still watching every episode til the end. Not much bonus footage. I'm probably just as excited for this as yall are. I miss yell being in Texas. On to bigger and better things. I'm happy for yall. Ms Logan has come out of her shell. It's great to see the better interaction with the camera. Keep up everything. Will be paitently waiting for part 2, 3, 4 and how many it takes. Love you guys

Quality entertainment is what I consider your videos. I haven't watched any TV in 6 years. So RU-vid is my entertainment. I've pretty much abandoned all my other channels at this point, lol 😆

"Can you take me higher" I think was creed if it hasn't been said 100 times already haha. Love big blocks. Had an old super stock big block in the camaro before it went turbo ls.

“Where were you when Mitchell Stapleton swapped in his big block on that January day” - Alan Jackson

I recently retired and have found out that these sites help take up time. I've watched a couple of your shows and enjoy them greatly. My only request is would you date them somewhere so we can follow in sequence. Thanks for making my days better. Steve Woods, 42 years as a law enforcement officer, finally retired.(Retirement is not all it's cracked up to be)

Suburban’s are SMOKIN hot right now!!!! Love this!!

Great job Mitchell and Logan no disrespect but I've done these jobs so many times I don't feel like I have to watch them but I can listen to them like their podcast either way though great informative video. You know me I'm here for the Long Haul and I can't wait to see it pound the ground

This is sweet! That engine is going to be insane in this rig.

I once swapped a TBI 350 in one of these OBS trucks as a teen. I did it in 6 hours from the time I popped the hoods of the dead engine truck and donor truck to the time I was firing the receiver up and driving it off. I did it same method as here. Hand tools and a cherry picker. I even had to swap flexplate from donor engine for flywheel on dead engine as receiver truck was manual trans and donor suburban was auto. Truck in question was 1993 Chevrolet K2500 with a 5 speed stick. Donor was a 1989 GMC suburban K1500 that had a GM Goodwrench stock style 350. I can remember helping put that Goodwrench 350 in the 89 suburban. Let me tell you. The front driveshaft on 4x4 machines is annoying to work around. Doubly so with the exhaust in the way

My brother loves these trucks! I’ll be watching, and I’ll forward them to him! 🔥

Another one bites the dust! The best accidents are the ones you never see coming that’s why why that trans didn’t drop. George will be a killer with it’s new power. Great content and a woman that doesn’t mind gettin dirty😂😂🐿

You guys have some of the best builds.going on right now. I'm. So pumped to see that big block get in there.

Late night watching this because I can't sleep, you know why this truck is so easy to work on? It's never been apart! That's a clean, real, one owner all original truck! This project has been interesting to watch and I hope it's as fun as it's been entertaining to watch.

For future usage taking the hood off remove the upper spring bolts and let the hood down put say a rubber mallet on the support so the safety doesn't catch grab a #2 Philips screw driver go to each end of the plastic cowl cover remove the screw on each end allowing you to remove the end peice of the cowl cover under that you will find the hinge pivot remove those bolts and lift the hood off no adjustment needed just set hood back on and put hinge pivot bolts back in and hook the springs back up and done! You could even take the hinge plates off the truck and install them back on the hood to make it easier to reinstall just a thought. Gonna be one sick burban!

Another fine friggin' episode guys. Nice to see a pro on a Sawzall. Good job Logan!

Every day you both amaze me on how well you work together and that your not talking down to anyone your just sharing your experiences Wish I was there to help!

I'm sure this may have been mentioned by someone else some other time, but when it comes to draining coolant....i went to a salvage yard and looked for the largest, flatest plastic fuel tank i could find and cut the top off around the top most edge leaving the sides up to help with splash. Best thing ever.

I put a blown big block in my 97 Suburban. I enjoyed watching your video. The swap is a huge project, but the reward is SOOO WORTH IT!

The GMT 400 is imo the best GM platform ever built. Great platform for speed.

You can shorten the trans shifter rod and re mount it like 2 inches higher and you will be happier than just using the cable, it keeps the steering interlock and reverse lights functional

The one thing I haven't figured out is the fuel sender wire. I also switched to analog gauges, and I accidentally cut some of the wiring behind in the gauge cluster trying to make enough room for the deeper gauges. I'm looking forward to more of your build videos. This is an awesome project!

Oh!!!!!!! all 8 pounds 9 0z little baby jesus, my wish has come true .. Big block time. Let's go dale. Uncle George let's go..

So pumped for this build, feel like we've been waiting forever. Any plans on Logan being the driver for this one?

You guys work as amazing as a team.👍 keep up the good work

You guy's are hilarious. "Higher" is a creed song and "never too late" is 3 days grace. Love the video. Can't wait to hear this beast

Hey you guys just wanted to say you both rock! I'll have to agree with you about one of the worst parts of pulling a engine is the radiator hoses! Try this it was a game charger for us! Get a wet and dry vac "shop vac" and suck it out. No mess no bs. One of my biggest pet peeve is cleaning up coolant!

Dream engine for sure. Cant wait to see it all.

Love the content can't wait for the next won. Much love and respect to u both. Been watching your videos for a while know love it

Had a 90ish dodge van a good while ago. Starter was going bad but it just needed help sometimes. I kept the dogbox loose so i could just move it and give it a wack or two when needed. Drove like that for months idk why. One day i went and got an oil change and it wouldn't start again when they were done. I beat the heck out of it for probably 20 minutes and finally got a start, then immediately went to the parts store to get a new one.

You can see my absolute gem of 92 suburban on my channel it literally had almost every single option with dealer options including the Mitsubishi TV which I still have the hook up for under the rear seat.

I would have definitely removed the front clip just to have the added room and so the engine hoist didn't have to go so high

Hell yeah, my daily driver is a 98 GMC K1500 Suburban, with 250,000 miles. Great content coming!!! I'm going to need one of those shirts!!

So happy to see this build come together finally. One: because I have known for so long. Two: I am reliving my build's beginnings through this,. Three: gmt400 ftw

Let's Goooooooo!!! Big Block Power baby

i am surprised how tall you both are, mitchell looks like an athletic but normal size guy and logan looks like a cute little pristine girl, after this video my thoughts have changed, mitch is a giant and logan is what i call a real woman; tall, tough, always ready for buisness (after coffee) but still manage to stay pretty all the time, world needs more women like her! at least one for me please lol

Friday AND a new video from you? Fuck yes!

You’re the reason my avalanche has a cam right now, since the Escalade had the LSA ! Now a 90s Burban! Oof yes!

Tbi 350s are actually super reliable with just regular maintenance. My 93 has 243k on the stock engine and it's still tight. They are shit for power but I love the reliability.

I’ve been waiting for this video

Suburban! Had my first in 93, it was a 75 3/4 ton 4wd, it would climb trees.. at the drive in swing the back doors open and watch movies in bed! Then I had a 73 then and 84 in 2015 got tired of people using my truck bed for a garbage can and taking shit out. Have had an 04 every since. 250k and I have a new motor on the way. Who cares about milage. I won't have anything else ever.

Pro coolant tip, buy cheap transfer pump at harbor freight and pump out the rad from the cap and you will get most of it out before you remove the hoses.

Can't wait to see that 632 in Uncle George 👍

Those Black tubs are great for all kinds of activities. Logan’s first appearance and this engine all showed up on that Blue Print engine tour if memory serves. I’m pretty sure the only way to tell if a 90 GM truck is original is if the paint is flaking paint off in sheets. Awesome that you guys are going to give it body off frame treatment to preserve it.

Damn, this is making me miss my '97 GMC 'Burban !!! Had a white one with a 6"+ lift with 37's, (2) KC light bars, full-size spare on the huge home made roof rack, etc.. My buddies nicknamed it the Kangaroo Hunter. One night, someone ran a light and totaled it!!! How the h#77 do you not see an 8' tall monster like that rolling down the road???!!! Can't wait to see how this turns out!!!

That hinga dinga durgen dug up some old memories the second you said it. Awweee the good ole days.

Great Video. Got a 93 K3500 that will eventually get a 454 or 502. And just picked up a Mint 99 OBS suburban that I'm going to drive the hell out of and when the motor gets tired I'll flip a coin between Big block and 427. Keep up the good work you guys make a great team.

Man I've rebuilt 2 5.3s and been through like 5 4L60s just to own and drive my suburbans and nobody understands why I like them so much. But Mitchell fricken gets it! Uncle George is gonna be sweet! I love the 3 burbs and they give me very ambitious ideas for my own.

I CANT WAIT TO SEE THIS!!!! A good rock song for pulling a engine hmmmm We didn’t start the fire 🔥😂

I had a 1994 single cab silverado with the original 350ci with 300,000 miles on it and it ran awesome. It had some rust but it wasnt bad. I had planned on building the truck but life came knocking and i just couldnt keep it. I would like to find another one eventually

Big block time!!!!!!!!!! While you are building the exhaust you should do some equal length 180 degree headers with an x pipe and either y it to a single exit or go duels. Have some nascar sound with a big block

Man, I been here since you were in the 20k range for subs man. It's awesome to see this channel grow, and you keeping it the same, down to earth, simple, and to the point. Y'all rock. Keep it up, and I can't wait to see that big block pounding the ground in that burb.

My buddy used to drive one exactly like this in Highschool. I'm going to send this to him so he can enviously watch and see what could have been

When I put the big block into mine, I removed the grill and cut the top of the radiator core support. I made new support brackets so I could put it back together afterwards. I also pulled back the carpet and cut a removable access panel in the transmission tunnel, so I could get to the bellhousing bolts easily. Once the big block was in place, I had zero room at the firewall

Yes about beating on the starter! We used to do it to my moms Blazer all the time

Try using your wet vac to suck the fluid out of the cooling system as you disconnect the hoses and afterwords to drain the block. I have not tried that but I thought it was neat when I saw it on Vice Grip Garage. Thanks for the videos

Shaking the crap out of a trans trying to break it loose “Rock you like a hurricane” Just subbed, love the content makes me want to work on the old Tahoe. Yes I know Rock you like a hurricane was way before 2000 but it works, hey I’m old

So much win for this build so far can't wait to see the progress on this one I've had several suburbans and they are amazing

Wow that big block is nuts.! This build is so awesome.! I can't wait to see what this landyacht can do. 👍

Love the video and can't wait to see the progress!! And as far as early 2000's rock songs to work on stuff, blunt force trauma by damageplan. Perfect for hammering on stuff lol

Putting a piece of hose on the petcock probably would have been less messy draining the radiator. This is going to be a cool build! 🇺🇲🦅💪

GM used 10,13,15, and 18mm headed metric bolts on the driveline in the 70’s, 80,s and 90’s. In the mid 70’s they swapped about half of the TH400 to metric threads, and left the rest standard thread, silly but working on them all those years it’s normal. Funny to see younger people figuring it out! There are block drains on both sides of the block above the oil pan rail, prevents the coolant waterfall!

Freaking SWEET!!! and on my birthday too of all days 🤘

been waiting for the big block build ✊🏻

Now this is my style of build!!!! Big blocks for everything!!! My go to was always Chevy Big block with NOS!!!! gets anything down the track!!!!!! 😃😃😀

Hooker headers makes a shorty header for the 454, I know because I was looking into upgrades for my 99 2500 suburban when I had it. 😁 this build makes my heart sing 🤩😍

I been waiting for this to come can't wait to see the final product and Logan and you are one of the many reasons I watch the channel

3 conscutive generations of long roof GM SUVs! Can't wait to see what all you do on Uncle George, maybe we can get him together with Storm for some pics!

When a shitbox gets a big block. An Angel gets its wings. This warms my heart lol

I am also 5'9 and it's handy at times like sitting on the inner fender working under the hood vs being leaned over the entire time, but God forbid you have to get something off the top shelf in Walmart 🤣😭

On the 1996-2000 gmt400/k1500 steering column shifter is a cable coming from column under the carpet through the floor on drivers side under the seat to transmission. Might be able to put a little newer steering column in to have a shift cable. Just wire up your lift yourself. If you can wire a car with efi never designed for obd2 efi you can handle a simple 110v or 220v circuit for a lift. Run wire from source in conduit overhead to your lift and hook up the wires

"I can't wait to get that thing in there!" AHHH, THATS WHAT SHE SAID! 😂😂😂😂

So excited for this build! I know it’s been in the works for a while. It’s going to be so badass!

Content reminds me of that sleeper vid back in the day haha, another awesome vid guys love following for here in Australia 🇦🇺

having been along for the ride since you visited PFI, the time taken to film and produce good quality entertainment is appreciated. I am sitting looking after our 5month old puppy after his operation today. 0230am here and a great way to pass the time watching great content.

Oh man I'm hyped for this build! Very exciting stuff yall!

Hell yeah man! Doing it up right. I'm pumped to see this ripper on the road and track. I have. 2004 suburban. It's the most comfortable vehicle to take long trips in. It rides out so nice and nothing is expensive to replace.

Mictell and Logan no wasted time here I enjoy looking for your content, if I lived close too you I would have helped you wire that lift! Have a great weekend you too.

Dude you making fast suburbans is like my wet dream of all things vehicular. My ideal suburban is a 69 with A6BT and Allison and Atlas type 2 Transfer case a Dana 60 end of the nose and a full float 14 bolt under the ass end. Is an absolute bulletproof rig from start to finish. You guys are building stuff that absolutely makes me smile

Glad to see you guys are starting a new project! I see you have a stout trans to put behind that 632. Great video content, great truck! My '94 K2500 Suburban is a f'n' beast w/1 ton rear axle & 454 engine, you won't be disappointed! Right there wishing I were able to help you & the lovely lady Logan pull wrenches on that truck, it will be a nasty customer when you get it repowered! Looking forward to all build episodes, I'm there, & thanks for the cool video, man!

Well then.... And I thought all y'all did was NASCAR history. Hell yeah guys, this is awesome!

I've been waiting for this build. I'm currently building a Mopar big block to put into my '83 RamCharger

Looking forward to more content on this build. 👍👍👍 Going to be a fun one

This build is absolutely sick and i thought Uncle Rob on the Esco are crazy🤘🏽Can‘t wait to see more of it. A fitting song while pulling an engine out could be Aerosmith „ I dont want to miss a thing“ and something is still connected😆

Found your channel, watched all of the uncle Rob videos… and now I’m just hooked on your stuff and I want to build a race car too!! Thanks Mitch… Suck it!! Keep ‘em coming, love your content.

This is a project I think a lot of people gonna be able to relate too and may have sitting in the driveway

Glad to see George is finally getting his new motor can't wait to see that land yacht runnin down the road tearing things up and breaking hearts

just got my own uncle George project! Cadillac 500 with sm465 though. Great videos!

The thumbnail says it all. Gmt400 !! Hell yea
