My parents have a 2500 Suburban with the 8.1L, I remember we were towing a 21 foot boat going up a very large ramp from one freeway to another in overdrive with the cruise control on 85 and it never lugged back or lost mph, if anything it was accelerating and didn't have to drop a gear. It was a very underrated platform that lost all the glory to the new Duramax. It's an excellent choice for an ugly truck.
You are going to LOVE that 8.1! Owned 2500HD CC/4x4 with the 8.1/Allison for 16 years. Burned no oil, ran like a top. Gobs of torque. Did have cold start knock, but only for 30 seconds or so. Don't ever check MPG...just put your right foot down and smile! : )
Another awesome video!! So you kind of inspired me to finally buy my first truck. I scored a heck of a deal on a 2003 Silverado 2500, not an HD. Has a 6.0 LQ4, 4L80E, 281K miles and I got it for $1,500 from a friend's tow yard. Super stoked to finally have a truck.
Very cool. Although LS stuff is a tried and true platform that's great, I also like being different. My '86 C10 has a 514" Caddy. Can't wait to see that 8.1 fire up! *Fun fact, the 8.1 as well as all the old traditional big blocks were built in Tonawanda NY. 40 miles from my home. All the current LT engines are built there today.
I also everytime I hear somebody argue against an LS and say they dare to be different I think you dare to spend a lot more money to do the same thing go ahead and slap a turbo on that crank up the Boost blow the bottom and up
I had a 2001 Silverado 2500HD w/8.1 and Allison in a service truck when I was working in Wyoming. I absolutely loved that engine, but I'm glad the truck had a company gas card. It got 9 mpg no matter what you were doing with it.
I have 2003 class A moterhome with a 8.1 4L80 E. it has 64000 miles and run great. Also have a 67 Camaro with a ZZ502 both great engines. I will be watching.
Heck yeah. Love that 8.1 my boss has one in a 3500, the motor mounts broke twice under normal towing conditions. Might want to beef them up for that turbski. Also I think you were sitting right in front of my daughter and I at LS Fest East for the burnout competition.
Cadillac 500 was an awesome engine! Production began in 1970 exclusively in the Eldorado. It was rated at 400 HP and 550 lb-ft torque. I believe compression was 10.5:1. From 71 to 76 it was available across the Caddy line, standard depending on model and/or trim. 77 & 78 they were available by special order in factory limos only; GM pretty much dropped big blocks from all passenger car lines after 1976. Cadillac was their "Golden Child" and could get away with it. My buddy and I installed a 71 500 in his 71 Trans Am in the early 80s. The 4th hard launch ripped the passenger-side subframe mounts out of the body. The 500 went to the back corner of his dad's shop and the TA went to the crusher. The 500 may still be there! Anyway, I think the 8.1 is a great idea! "If it don't go, cube it!"
@@LawrenceTolman, you are definitely one of the most talented mechanics on tv, it's awesome to see you do things for yourself! I'm here for the long haul! Can't wait for you to teach me some more about setting up a ring and pinion backlash
Just installed a Raylar Eng. 201 cam and Raylar modified intake into my 2001 Silverado 8.1 Vortec w/5spd Allison. Fired it for the first time yesterday, tune will be installed today. I also have JBA shorty headers into stock exhaust and installed 4:56 gears last summer. Truck tows a 15,000 lb. 5th wheel. Will be end of July when I see if the new mods improve my hill climbing ability at max GCVW.
100% agree. LS has been done to death. I’m restoring my 87 and everybody and their brother asks, “you gonna LS swap it?” No, way overdone. I’m gonna be putting in a Dart 400 small block with AFR heads
LT I drive an 05 GMC 5500 rollback for a living and speak from experience when I say the 8.1 has plenty of torque to move a 12,000 lb. Truck down the road. So you should have more than enough to get in a little trouble. With that being said, I'm considering the same swap into my square body stepside. As far as I know Raylar engineering is the only company for aftermarket support of this motor. I'm now a subscriber of the channel and look forward to updates... good luck with the build.
I am looking forward to watching all the videos on this you have listed. I have a 2014 Z71 Silverado and I also have my old work van (I am retired now) which is a 2000 3500 Express with an 8.1L. I loved driving that van. It has positrac an weighed over 8k pounds and would light the tires up if you got on it. I love my Z71 and at my age, it is probably my last truck and I really want to have some fun with it.
I have 2 each 8.1L engines 1 is brand new the other has 30K but was using oil. Thinking about putting one in my 2002 Avalanche. Love the channel I will be watching.
If you can show the world how to make power cheap with an 8.1 you'll be a hero! Whenever I hear "weak pistons" I think not enough ring gap, so hopefully before it gets boost you pop the pistons out and at least check the gap if not open it up.
Man! This is the coolest channel on youtube right now. It was cool to hear the story and you obviously write your goals down because you are checking them off the list in a timely manner! Looking forward to seeing what's next!
Nice project ,just keep an eye on the oil consumption I will go with a oil catch can and make sure you install a new crank sensor they are not fun to replace on the engine is bolt on.
I have a 96 C3500 dually with the L29 454 you have inspired me to build my sons & I all owners of our own ugly truck. Got a locker 4.56 gears but with 300 plus miles strong but needs a rebuild. I did hurt it a little burned the brakes pulling 18,000 lbs. up & down a hill not too steep but it was enough to scream the engine to 220 degrees once I reach the top. Still runs but won't be towing that much anytime soon. I need a rebuild or maybe find me an 8.1L or stroke my current engine. I just subscribed be interesting to see the build. I myself is a little anti LS too many out there.
Dude, I dig it! Props for going outside of the box. I’ve always wondered what the 8100 would do with a little work. That big exhaust should be perfect for that ole girl to breathe too 😎
8.1 is awesome. For my uses, it's really hard to beat an LS though. The 8.1 is sweet and can be built, but you will pay to make significant power over stock. Should be cool to see the build though.
I bought a 50' Buick last year which came with a small block and an auto from a (what I was told) mid 90's Impala, mounted in the front clip of a 77' Monte Carlo. It also has the axle from the said Impala. I'm in the planning stages of its next build right now. Yes the LS is an awesome platform with a ton of aftermarket support... but like everyone says... it's been done. I've always been different anyway, so I'm trying to figure out what I want to put in it. It's already set up for a small block so swapping in a newer, healthier small block (a 383) would be easy (and practical). I'm also eyeballing a 454 or 502 option (they would be fun). I'd like to put a Tremac 6 speed behind it. Hell... the thought of a Duramax even tiptoed through my brain... but that's a BIG can of worms! I never thought about the 8.1... this has caught my attention! Subbed...
Very good presentation....I have ever done an ls anything....but I have been thinking of how I could put a duramax in my 68 impala....that would be different...but the 8.1 does seem a more practical swap....and there are a couple of sources for 8.1 stuff. I think I will subscribe...this could be interesting!
Just subbed..like the engine swap u have planned..look at the L21 bbc it’s a gen6 454 has coil packs 1x cam signal and 24x wheel..you can stroke it to 496 and has lot more availed parts..
Hey Lawrence, I’m becoming a sub and can’t wait to see your progress. This is going to be a different fun build. Are you going to be pulling the pistons and changing the ring gap for boost, or are you going to leave the short block alone?People can be real dumb and there dogging me on my build to!
I did a 8.1l swap in my 01 2500. Just a fyi. The 6.0l and 8.1l y pipes are the same. 4.8l 5.3l y pipes can be used. But the drivers side flange needs to be changed.
The biggest problem with that engine is it's low rpm peak. 4,200 for peak HP is where it falls short and causes problems for being a high performance candidate.
That's really cool what ur doing everyone I know are 6.0 freaks I always told them to do up a 8.1 liter they oh no u dont want to do that 6.0 is the way to go. My buddy years ago put a 500 caddy ina 78 chev pickup I couldn't bleav the torque it had we had more fun with the 500 caddy then the 454 that was in it
Go for it! the more big blocks the merrier. not sure what year your truck is, but I have a few more videos to come on the swap with a lot more swap info
@@LawrenceTolman "user *may* experience increased tire wear" lol. Solid plan, after reading your thoughts, I realized that your logic is solid. My bad.
@@LawrenceTolman I have the 8.1 and the allison transmission so I'm going turbo to match diesel numbers for horse power and torque it's in a 2003 gmc 2500 hd 4x4 short bed crew cab ....
You better be ready to dump some money for forged internals... that engine cant hold boost for shit. Theres a reason no one I mean no one uses them in swaps that's because its expensive waste of time you could pull more power from a junk yard 6.0 and have less of worry than a built 8.1
Those are okay if in stock form but have a weak bottom end very little aftermarket support not sure why anybody would go for one of those instead of an LS but don't expect any crazy horsepower numbers there's a reason why GM quit making those
I have that same engine in my eagle 230 eliminator boat.......bad ass motor, ..........my boat can do 80 if the tide is right and the trim is dailed in.......... good choice, so you can still run this on your factory ecu, pretty much plug, tune ,and run!!!......does it have knock sensors like a 3rd gen ls??
yeah, its more or less plug and play. it has two knock sensors (one on either side of the block) so it will need a few wires lengthened and such, but overall, not bad.
I'm so excited to get this thing swapped in, I think its going to be a blast! Thanks for watching everyone!
2003 and up oil fill is already curved for you. they had to clear the other style DBW tb

They are a great engine. Have a mildly built one with a pair of 67mm turbos in my Nova.
that sounds like a blast for sure
Damn. This man has a great presenting voice.
Thanks!
Big cubic inches are great for nitrous. If you go turbo . It will take a big one .
thats perfect, because i ordered a big one
Excited to watch this build, Im all for a good ls engine but Im happy to see that come out and be replaced with the 8.1!
The 8.1 LTR is an awesome engine. They put it in the H2 as well.
I never knew thats pretty cool. I only seen them with a lq9
yeah, I had no idea the H2 came with an 8.1, thats badass
They produced them into '07, I've got a Sierra 3500 with one of those big ol' 8.1s under the hood

good choice this thing is superior to a ls
An awesome motor to do that's very very unique would be a turbo charged ford 300 with the Windsor V8 internals
8.1 had major problems with crank sensors while driving down the road. Have to always replace sensor with OEM, was a pain in the neck.
anytime I've used a non-oem crank sensor, it seems like I've had trouble

Nice choice man! 👍👍 That's gonna be lots of fun!

You don't need 4.30 gears with a torquey engine like that. It will be just as fast with a 3.70 or 3.73.
3.23 is efficiency and top speed, 4.10 is acceleration but loses top speed, also 6-10 speed trans can run 3.23/3.73 even in kodiak/topkick.
The biggest problem with that engine is it's low rpm peak. 4,200 for peak HP is where it falls short and causes problems for being a high performance candidate.
I suppose a larger cam and a turbocharger could cure that
Lawrence LT Tolman. Exactly, cam swap and valve train upgrade is the way to go.
That Engines a beast!!
I think I just realized why you looked familiar, your one of the guys from the Power Nation channel I think.
I am, (or was rather) between 2015-2020
Low RPM big block is best for trucking.

because of the shape of the 3 bolts in the pattern, I dont think so.

Got my subscription due to your engine choice.
Appreciate it a ton!
There is a reason no one swaps a 8.1, it's a turd with next to no aftermarket. What aftermarket is out there is $$$ and marine based
Lucas Beadle both valid points, but there’s just something cool about a big block with a turbo...
@@LawrenceTolman
I have the 8.1 and the allison transmission so I'm going turbo to match diesel numbers for horse power and torque it's in a 2003 gmc 2500 hd 4x4 short bed crew cab ....
Have owned two 8.1L trucks. Still have one... A turd it is not. It's just badly held back from the factory. Happy to see it used here.
It's still a BBC.. what the fuck do you mean they have no aftermarket? You can use ANY Gen 4-6 head on it with the correct cylinder head gasket.
All man that's gonna be a tq monster lol.
I'm planning on doing a turbo 4 cylinder S10 something a lil different also lol
Always wanted to see someone mod one of these up. Sub'd.
thanks! hopefully it'll be pumping out some serious numbers some day
You better be ready to dump some money for forged internals... that engine cant hold boost for shit. Theres a reason no one I mean no one uses them in swaps that's because its expensive waste of time you could pull more power from a junk yard 6.0 and have less of worry than a built 8.1
An old school iron block 454 wouldn’t be a bad heartbeat
Those are okay if in stock form but have a weak bottom end very little aftermarket support not sure why anybody would go for one of those instead of an LS but don't expect any crazy horsepower numbers there's a reason why GM quit making those
Caddy engine in a C10. I like the way you think.
Those engines are monsters, so excited to see that
Did ext cabs come with short box? Or did you mean the standard box? Btw nice truck man! Can’t wait to start working on mine
I guess I meant "Short box" as the 6.5 foot bed vs the 8 foot.
Heck yeah! I knew it! That will move that truck damn good! Good choice!
I have heard those suck gas I mean they only came in 3/4 ton or bigger but I mean a camshaft would make a big difference with all those cubic inches
you can be guaranteed it'll suck more gas
I've heard that engine is a beast
it certainly weighs as much...
I have that same engine in my eagle 230 eliminator boat.......bad ass motor, ..........my boat can do 80 if the tide is right and the trim is dailed in.......... good choice, so you can still run this on your factory ecu, pretty much plug, tune ,and run!!!......does it have knock sensors like a 3rd gen ls??
yeah, its more or less plug and play. it has two knock sensors (one on either side of the block) so it will need a few wires lengthened and such, but overall, not bad.
I seen that church before in that one shot in the beginning. Are you from Michigan?
nope, that one was in TN
