03 Jojo not really I am an automotive tech but this is my first time doing a swap like this so done some research ang bought what I needed and just went at it I love this truck now
If you're mechanically inclined, it certainly helps! So does having some buddies willing to sacrifice to the greater cause! LOL thanks for the input and the clear shot of TTR's Crocs & Socks!!!!
Thanks for all the great Q&A. I inherited my dad's 78 longbed c10. I built a 350 for it and I struggled on the idea LS swap. I've learned alot watching videos such as yours and I'm going LS swap. I'm keeping dad's C10 old school sbc but I'm getting another shortbed to LS. Thanks
I got the motor into my truck! It should be done soon and on the road! Keep an eye out for a video of it! I want to thank you guys for the motivation to finish my truck!
You made a great point when you said someone might say "I can do in one hour what it takes you 10 hours to do..." To them I would say that may be so, but my ten hour time is spent taking my time, meticulously paying attention to every detail, checking and double-checking so that it is done right the FIRST and only time. Not that your job wouldn't be done right, but I don't do this for a living...that is, I don't do it every day all day long so much that I could do it with my eyes closed like you might, so please take that into consideration when blowing your own horn about how awesome you are, or how slow I am! My proverbial 10 hours is spent taking my time, not rushing or getting in a hurry, and having fun! I don't care if you can do the same thing in one hour..you know, good for you, what do you want, a parade? I'm not made of money so I have to make sure that what I do is done right because I cannot afford to have something break, and have to re-buy (is that a word?) parts just because i got in a hurry and f'd something up. I literally cannot even watch these shows anymore where they say "we have 6 hours to do a complete frame off restoration..." (slight exaggeration, but not by much!) because I know that corners are inevitably going to be cut, and unimaginable and more than likely, unfixable problems are going to surface probably as soon as the project rolls out the door! Anyway..great show! Have a great day and keep up the good work!
2 people myself and a friend ripping out his motor\trans from a 80's Firebird, rebuilding a junkyard motor, dropping the motor\trans in, wiring, fueling, fabricating air intake system, troubleshooting, install AC/PS/Alternator/accessories, and troubleshooting it took us about a month(not total time) from beginning to finish working sometimes 1-4 hours during the week and 4-12 hours on weekend. Tuning was done with a friend of mine on his dyno.
@@UNITEDBYTRUCKS now I just need to find a home for the LS3 collecting dust wrapped in plastic in my garage. My first truck was an 85 Chevy short bed that I bought and did not run. Ripped the motor and trans then replaced it with a crate 502 I got with birthday money and saving. Stupidest thing I ever did was sell that truck. Now they are nearly impossible to find unless you want to spend what a new truck cost.
I get this question at every show and cruise. I shouldn't have done this, but I did it for record keeping "if" I ever sell my truck. I kept a detailed log of a every part, big or small, on my build and what it cost. It's scary how fast it adds up. In hindsight, I could skip some of the new parts and work I did, but I wasn't sure of condition at the time with the engine and trans. I didn't get to see either run and drive so I error-ed on the side of caution and rebuilt. My OCD also got the best of me and I spiraled down that wormhole a few times. All in all, I wouldn't change it for the world. Fortunately, these trucks are at least holding their value so I won't get hurt if I sell. It's all in what you want out of it. I was brought up on fuel injection and computers, so that is what I wanted. I know how a carb works, but it is still a bit like sorcery to me. You can most definitely do it on the cheap, or you can spend a fortune. At the end of the day, do what you are comfortable with.
So very well said! I kept up with the same on Teddy but have honestly yet to tally it up. Ron has the same but we didn't tally it up completely. We decided to work with round numbers that were easier to digest and tack them on to the engine/trans cost as well as tuning. I'm sure it's not the exact answer some want, but it's the best we could do and feel like it gives us garage builders a good frame of reference.
Rusty Wrenches my ocd is the same. I just wanted it right. If it took longer so be it. That said the other half of me just didn’t want to see the numbers so I never really kept up with it.
Buddies just did a swap in a older c10 I believe they used a factory Jeep electric fan setup and it fit perfectly even controlled the whole thing with hp tuners
"You're already there" . Man I am the world's worst at "while I'm here I might as well..." to the point that it delays my projects endlessly. I really need to learn the "it's good enough" lesson.
Great video I got a 64 c10 from my dad and i have a 5.3 with transmission and a bunch of parts including wiring harness with computer, radiator with electric fan,kwikwire harness and dakota gauges What i don't have is the skills to put all that together but im all hands on.I hope i could get some help to put it together that truck means a lot to me i just have to get it running. It will be a great candidate for your next video! 😁😁😁
I got my donor truck with my LS for free, just had to go pick it up & bring it home...haven't swapped it yet though, I'm just starting my chassis, so can't say how much exactly I'll have in the engine once I get it in the other truck...I'll be using the transmission & differential from the donor truck as well, so cost for acquiring the entire drive train for my build was some gas money...won't know how much the engine will cost to build for a little while yet...but if you apply yourself, you can pick up an engine super cheap...
I prefer to pick up a low miles 5.3 with direct injection...easier fuel system, cam swap (DoD delete anyway so may as well up the power a bit) alone gets the motor to around 450 hp...but you cant beat free if its low miles and don't have to rwbuild it
I have a 90 suburban 2wd 3/4 ton with a 350. I also bought a part truck with a 4.8 ls. The flex plate is cracked on 350 and 0 oil pressure when warmed up. Now the 4.8 has been sitting a few years so it will need work. My plans are to change flex plate and try changing oil with better oil to get my winter ride through winter... Then do ls swap next spring.
Just a bit of information for who it may help I did a LS swap on on a 85 c10 and I modified the sending unit by relocating the float and putting it on the return tube it has a spot for rivets the float is accurate the pump I had to cut the tube for the pump to fit so it can sit as low as possible for when the fuel is low this was a way for me to not spend the money on the correct tank for this swap it works and been working of course I purchase a stack tank for the 85 and the sending unit for the 86 and I used the pump from a 2004 Chevy Tahoe that was from the diner vehicle as far as connections it’s simple everything was easy it took me about 15 minutes to assemble everything after getting new tank sending unit and pump the truck runs great and it’s a daily driver .
I was able to do it for around $3-3.5k including the motor and trans. I bought a wrecked van for $1300. took the 6.0, 4l80, stock exhaust, drive shaft, brake booster and stock wiring harness and sold the van body for 800. Then I bought: -small block to LS adapter motor mounts -sent the computer and harness to 150 tunes for wire cut down and reprogramming -like 500 in hoses and external fuel pump -bought an after market shaft for around 700 -aluminum 3 core radiator -aftermarket floor shifter - then about $6-700 in odds and ends.

Price of the harness, PCM, radiator with a union for the steam port from the LS, and then tuning it. That's the swap done. Hard parts are bell housing, flywheel, flexplate, brake booster (or delete) options, clutch master etc. Then you can figure if you want to run OEM GM VSS sending unit on your trans tailhousing for the PCM to use cruise as well as better for economy. The electric fans or just jerry rigging it to the old clutch fan. If you're going 4x4, you better start thinking np205 and $190 to have the VSS reflector ring adapted to your transfer case tailhousing for quick and painless option. Speedo fix is driving by mobile until you swap out your gauge or adapt it over from the VSS. If you're running an LS1, you have to adapt the crank with a specific flywheel and if you're going manual trans, prepare to grab your knees... It'll sting to get your NV4500 mounted. So many variations on that unit that you had best visit Advanced Adapters to view their tech for using that trans. It'll be worth it for a beast of a 4x4 and that's where I'm headed with my K5. If you don't move, you'll lose! Best to just bite down and get it done... Don't camp on it because it's a terrible waste of your time and a part of your life that you'll never get back. Bright side, your truck will be worth a whole lot more money if you do it right by the time you finish it and you'll have a sense of accomplishment!
Love the truck. I'm presently looking for a short bed 2w.d. I have a 5.3 in my garage that came out of a wrecked 2013 4w.d. with 32 k miles on the clock.
you know the type of square body is hard to find is the extended cab type that is a rare to me type. just helped a friend rebuild his 350 and fix some of the common rust fix issues on the corner of the cab. but to be honest the extended cab looks amazing but a rare type
I hate this question / discussion . I'm north of 20 grand in my 87c10. If I had to do it all over I would have put aluminum heads on a rebuild 350 and fitech fuel injection
@@therealchucktaylor3392 just remember .....you get what you pay for , these guys that are rebuilding their old wire harness are the ones posting question,a about why their truck isn't idling or throwing codes . ....i bought the best .... I saved my money until I could , I'm broke also
North of $20k on your swap? Easy to do but I hope you started with a crate LS3/7 etc and all new components. Nothing wrong with an EFI small block. I'd look at Holley Sniper over FiTech though.
I totlally agree it took me 6 sat at 8 hours each sat. Thats about 48 hours. I didnt do the rockers and springs cam so yeah. The fuel system alone took a whole day. The wiring was about 2 sat.
I'm a new subscriber I've enjoyed and learned a lot I'm going to LS swap my 2018 Chevy ZR2 Colorado as soon as the warranty is over I'm building the engine now it's a 4.8 that's plenty with trick heads and cam and headers plus a tune can't wait
I have an 77 c10 and what I did for fuel is an 87 tank, 87 sender , Corvette fuel filter, and use an compression fittings to hook up my ptfe hoses to my factory hardlines. Works perfectly
Man you guys are awesome I know I’m late to the party. But man so much info on LS swapping. I want to do my 86 Sierra here soon. Great job on the small details and for sharing the knowledge. 💪🏽😤💯
I work at a hot rod shop and have done my fair share of LS swaps, that being said you guys should try the BP harness they are cleaner, way better looking, and way easier to install. I did a PSI harness and ECU on a custom square body quad cab a few months ago and the ECU was un tunable and took more time to install.
Just finished up my first ls swap by myself, i did a bunch of unnecessary modifications, but my harness cost me 400, and i had 200 in motor mounts, 200 in a trans, and could have done the rest for free. Probably have 30 hours of real work by myself making it run, not including exhaust. Very realistic, but ive also done several engine swaps by myself, just not ls swaps.
Last question: So you went with a 5.3 for Pecos. I'm am contemplating a 5.3 vs a 6.0 (looking at a few donor vehicles between 2005-2007 with both engines). I spoke to a fellow at Summit who tells me to go 5.3 because they tend to be less problematic/last longer than the 6.0. (i.e. 6.0 has issues with oil pressure, etc) While I don't have to have a "drag truck", the 6.0 sounds sexy and it will come out of the donor vehicle 400hp-ready which is my HP goal. Hate to ask such a long winded/involved question, but what do u guys think...? (each vehicle has between 100-120k miles on them)
Can't go wrong with either. Never heard of any oil pressure issues with a 6.0 specifically, though I'm no expert. That said, if I had a choice and your goals, I'd go with the 6.0. We'll be putting a 6.0 in the new project TTR just landed for the UBT audience.
I have a 1986 Silverado short bed dual tank it was my fathers who passed , but it don’t run should I LS swap and what would it cost DIY to get it back on road ? It’s been sitting for 15 yrs but never wrecked that’s what I want daily driver ! Need to get fire under me would be sweat ! Seeing how nice y’all trucks are!
We have a 1986 GMC Sierra Classic 2wd lwb my father father bought new. Body is solid GA truck. Trying to figure out what to do with it. It is running driving with a GM target 350. Truck is still in GA about 50 miles north of ATL. Just found you guys and look forward to following your channel.
Second time around watching this build. Great to see the friendship between you guys. Great build. Although I have a 53 truck with i think is the third motor in it. It was long after I put in this 350 that I'd. Started thinking about ls swapping. Maybe next year I take the time to do it. My last work truck had a 4.8 but my new '17 has a 5.3. I love the power of it so ill be looking for that up hear in PA. The only thing about the trucks up hear is they rust out. Plenty of good running motors though. Thanks for all the detai) information.
You can certainly spend any amount of money. I’ve seen crate engine 7 liter ls with twin turbos listed over 25 grand for just the engine assembly. But HP per dollar is on a steep decline after a few thousand. As in stock 350 making 200 hp I buy an $800 6 liter a cam spend 2200 on motor and install make 450 ish hp.. that’s $12 dollars ls per hp. I could spend 30 grand and consistently make 1000. That’s $30 per hp. But that’s 37.50 per hp but it’s $49 per hp from the original 3000 dollar upgrade. Nothing wrong with that if you need 1000 plus, but for most of us the 450 is more than enough and a bargain, past that I can’t justify it in my 85 k5 that I just like to drive back and forth to work and wherever else I go and want it to be dependable, strong, fun to drive and more economical than the carbed 350 that’s in it now. I’m actually looking at a stock 6.0 with a 4l80 and transfer that will run me about 5 by the time it’s all done. Only because I haven’t found a 5.3 with a 4wd 4l80 anywhere and I want the strong trans. And I’m guessing a stock 6l will be cheaper and cheaper on gas and more dependable than a 5.3 tuned and cammed to equal it for low end torque honestly though a stock 5.3 with the 80 would be fine with me and plenty strong for what I need with maybe just a little tuning.
hello friend beautiful truck, can you please tell me the measurements of the rims and tires, I live in Germany, but I have it in Venezuela. It is the same color and my father gave it to me when he died.
nice work guys........you could of also saved money buy using the factory harrness that came on the 5.3......watch gear heads for life on youtube he show which 4 wire to hook up .....just so u know in the future....
I have a gmc 1997 sierra, i like it but it hhas high rpm, it goes pretty fast but something w the cylinder was wrong so its in the shop, it has a 4.3L vortec and im considering ls swapping it but i really dont know how much it is even after watching these videos
Gdmorning or gdnight this might be a old question. But new to the chevy game I bought my first 91 chevy silverado 4.3 v6 EF1. I understand I can go LS I know i need a LS motor cpu harness maybe trans. But witch motor mounts do i have to look up to buy. So I am able to run the LS.
It is, the only thing I think you might need some help with is tying the truck wiring harness into the LS engine and trans harness. Most everything else is nuts and bolts.
I’ve got a 1964 Impala. I’m wanting to do an LS swap but have no clue where to start. What LS motor should I go with and what’s gonna be the total cost when finished? Any help or recommendations would be greatly appreciated.
Man, that's a super hard question to answer. We like Gen 3 and 4 5.3s and typically end up with about $2500 in one aside from the cost of the motor and performance adders. Good luck!
Love all your videos. Going to swap my 87 r10 soon. What about trans cross member ? Can the universal one from summit work or ? Thanks for sharing you guys are awesome. +

If you're going 4x4, you better start thinking np205 and $190 to have the VSS reflector ring adapted to your transfer case tailhousing for quick and painless option.
Speedo fix is driving by mobile until you swap out your gauge or adapt it over from the VSS.
If you're running an LS1, you have to adapt the crank with a specific flywheel and if you're going manual trans, prepare to grab your knees... It'll sting to get your NV4500 mounted. So many variations on that unit that you had best visit Advanced Adapters to view their tech for using that trans. It'll be worth it for a beast of a 4x4 and that's where I'm headed with my K5.
If you don't move, you'll lose! Best to just bite down and get it done... Don't camp on it because it's a terrible waste of your time and a part of your life that you'll never get back.
Bright side, your truck will be worth a whole lot more money if you do it right by the time you finish it and you'll have a sense of accomplishment!
I bought a speedo for mine that works off of GPS
Power ground and mount your antenna and your done
Love the truck. I'm presently looking for a short bed 2w.d. I have a 5.3 in my garage that came out of a wrecked 2013 4w.d. with 32 k miles on the clock.
Whoa! That's super low mileage. Good luck!
You want one that’s already fixed up ? I have a 1985 square body for 10k
Gen 4 5.3 little bit more work for a swap but hope it’s been well!
in my truck, I will be going with the 383 stroker.
Sweet!
Can't wait to ls swap mine, aiming for next year
Sweet! You'll love it.
Love the truck TTR GREAT JOB by everyone involved!! Thank you for all of the information that’s involved.
Thanks for tuning in!
I made my own electronic speedo from a 1990 G20 van modifie to fit C10 cluster for $25...can wait to see if it work! :D
Sweet! Let us know how it turns out.
you know the type of square body is hard to find is the extended cab type that is a rare to me type. just helped a friend rebuild his 350 and fix some of the common rust fix issues on the corner of the cab. but to be honest the extended cab looks amazing but a rare type
Yup They are. Somebody actually tagged us in one the other day. Not a factory option but the third party guys did it well.
I hate this question / discussion . I'm north of 20 grand in my 87c10.
If I had to do it all over I would have put aluminum heads on a rebuild 350 and fitech fuel injection
I'm going to do the same thing to my 87. I've been quoted around $7,000 to $8,000 by 4 different shops.
@@therealchucktaylor3392 just remember .....you get what you pay for , these guys that are rebuilding their old wire harness are the ones posting question,a about why their truck isn't idling or throwing codes . ....i bought the best .... I saved my money until I could , I'm broke also
North of $20k on your swap? Easy to do but I hope you started with a crate LS3/7 etc and all new components. Nothing wrong with an EFI small block. I'd look at Holley Sniper over FiTech though.
If that $7-8k includes engine and trans, labor, hard part, etc, I can see how it makes sense.
@@UNITEDBYTRUCKS I'm way past that point , but you get what I'm saying
If you take a 2002 Silverado dash and cut the corners just right. You can use the gauges to from that Silverado and have a speedometer and everything
I totlally agree it took me 6 sat at 8 hours each sat. Thats about 48 hours. I didnt do the rockers and springs cam so yeah. The fuel system alone took a whole day. The wiring was about 2 sat.
Yup! It’s no small task but it’s one worth doing.
You can use a 91/92 suburban cluster and have everything hook up and work. That’s what I did on mine and it’s now in Texas running around.
Cool! He wants aftermarket gauges.
UNITED BY TRUCKS don’t blame him they’re nice.
I'm a new subscriber I've enjoyed and learned a lot I'm going to LS swap my 2018 Chevy ZR2 Colorado as soon as the warranty is over I'm building the engine now it's a 4.8 that's plenty with trick heads and cam and headers plus a tune can't wait
Sweet! That sounds like a super cool project. Keep us posted on it!
Great content Robbie keep Pumpimg out them videos bro 👍
Thanks, John!
I have an 77 c10 and what I did for fuel is an 87 tank, 87 sender , Corvette fuel filter, and use an compression fittings to hook up my ptfe hoses to my factory hardlines. Works perfectly
Sweet!
Man you guys are awesome I know I’m late to the party. But man so much info on LS swapping. I want to do my 86 Sierra here soon. Great job on the small details and for sharing the knowledge. 💪🏽😤💯
Appreciate it!!
thanks fellas i bought a short bed 69 chevrolet over the weekend just a body
Sweet! Blank canvas.
@@UNITEDBYTRUCKS yes sir going too ls it and slam it to the ground it has sweet patina
@@jeremystrickland7767 my favorite kind :)
@@UNITEDBYTRUCKS yes sir robbie mine to bro damn i can't wait to meet you guys
What did you pay for it if you don’t mind me asking
I work at a hot rod shop and have done my fair share of LS swaps, that being said you guys should try the BP harness they are cleaner, way better looking, and way easier to install. I did a PSI harness and ECU on a custom square body quad cab a few months ago and the ECU was un tunable and took more time to install.
Thanks for the feedback!
You on the East coast VLM?
Lloyd Hardy Texas here.
Just finished up my first ls swap by myself, i did a bunch of unnecessary modifications, but my harness cost me 400, and i had 200 in motor mounts, 200 in a trans, and could have done the rest for free. Probably have 30 hours of real work by myself making it run, not including exhaust. Very realistic, but ive also done several engine swaps by myself, just not ls swaps.
Ls swaps are expensive. I may do it but it's pricey
@@jamesjones4309 they can be for sure. I've done 3 now, all under 1000
Cool video man. I LS swapped my 66 Tempest with a LQ4 on my channel they pretty good motors. I’ve put a ton of smiles per gallon on that car.
Heck yeah! That sounds like a bad ride.
The beer you guys are drinking is made 20 minutes from my house. We call it Pottsville Piss Water
Last question: So you went with a 5.3 for Pecos. I'm am contemplating a 5.3 vs a 6.0 (looking at a few donor vehicles between 2005-2007 with both engines). I spoke to a fellow at Summit who tells me to go 5.3 because they tend to be less problematic/last longer than the 6.0. (i.e. 6.0 has issues with oil pressure, etc) While I don't have to have a "drag truck", the 6.0 sounds sexy and it will come out of the donor vehicle 400hp-ready which is my HP goal. Hate to ask such a long winded/involved question, but what do u guys think...? (each vehicle has between 100-120k miles on them)
Can't go wrong with either. Never heard of any oil pressure issues with a 6.0 specifically, though I'm no expert. That said, if I had a choice and your goals, I'd go with the 6.0. We'll be putting a 6.0 in the new project TTR just landed for the UBT audience.
Had a 6.0, never had an issue. 5.3 is also a great engine.
I have a 1986 Silverado short bed dual tank it was my fathers who passed , but it don’t run should I LS swap and what would it cost DIY to get it back on road ? It’s been sitting for 15 yrs but never wrecked that’s what I want daily driver ! Need to get fire under me would be sweat ! Seeing how nice y’all trucks are!
Another sweet video, Kinda makes me want to LS swap my 69'.
Thank you! That would be cool but I bet it has a cool motor in it right now.
@@UNITEDBYTRUCKS Yeah it has 425hp 355c1 with fi-tech and aluminum heads - she goes
I will be over hauling a 1983 3/4 ton Chev Truck CK-20 like your site.
Thanks much!
i have an 78 3/4 ton crew cab i want to swap my tiered 350 to a 6.0 ls
What ac system (details) 🙏 🙏 🙏 like the part next to the radiator please sir
Stock LS AC with custom made lines to adapt to the LS compressor
We have a 1986 GMC Sierra Classic 2wd lwb my father father bought new. Body is solid GA truck. Trying to figure out what to do with it. It is running driving with a GM target 350. Truck is still in GA about 50 miles north of ATL. Just found you guys and look forward to following your channel.
Truck is not for sale. Just would like to make it a good daily cruiser.
could u have used the original oil pan
Yes, with Tejas mounts you can
Second time around watching this build. Great to see the friendship between you guys. Great build. Although I have a 53 truck with i think is the third motor in it. It was long after I put in this 350 that I'd. Started thinking about ls swapping. Maybe next year I take the time to do it. My last work truck had a 4.8 but my new '17 has a 5.3. I love the power of it so ill be looking for that up hear in PA. The only thing about the trucks up hear is they rust out. Plenty of good running motors though. Thanks for all the detai) information.
why not use the donar vehicle pcm and harness? I'm getting ready for LS swap, but I think I'm going to use the 4l60e in my K5 4x4
Old harness and too much work to re-work. We used factory pcm on this one
You can certainly spend any amount of money. I’ve seen crate engine 7 liter ls with twin turbos listed over 25 grand for just the engine assembly. But HP per dollar is on a steep decline after a few thousand. As in stock 350 making 200 hp I buy an $800 6 liter a cam spend 2200 on motor and install make 450 ish hp.. that’s $12 dollars ls per hp. I could spend 30 grand and consistently make 1000. That’s $30 per hp. But that’s 37.50 per hp but it’s $49 per hp from the original 3000 dollar upgrade. Nothing wrong with that if you need 1000 plus, but for most of us the 450 is more than enough and a bargain, past that I can’t justify it in my 85 k5 that I just like to drive back and forth to work and wherever else I go and want it to be dependable, strong, fun to drive and more economical than the carbed 350 that’s in it now. I’m actually looking at a stock 6.0 with a 4l80 and transfer that will run me about 5 by the time it’s all done. Only because I haven’t found a 5.3 with a 4wd 4l80 anywhere and I want the strong trans. And I’m guessing a stock 6l will be cheaper and cheaper on gas and more dependable than a 5.3 tuned and cammed to equal it for low end torque honestly though a stock 5.3 with the 80 would be fine with me and plenty strong for what I need with maybe just a little tuning.
hello friend beautiful truck, can you please tell me the measurements of the rims and tires, I live in Germany, but I have it in Venezuela. It is the same color and my father gave it to me when he died.
What did you use for your suspension & Shocks?
It's a simple spindle/springs set-up in front and a flip kit in the rear. Think they are Belltech shocks.
My dad wants a already done swap what should we look for to know if it’s a good swap
Drive shaft will cost as well.
i have C20 vortex 5.3l swapped it cost me 2500$
Cleetus beats his TSP 427 like a red headed stepchild into 7 second land. TSP is tough
Yeah, he does. And yes, they are.
Keep it up! Keyboard warriors will be keyboard warriors 😉
Thanks, man! So discouraging to see people like that. smh
Cant please everyone bud! true subscribers would watch you talk about a prius lol
Can you swap an LS engine into a 66'?
nice work guys........you could of also saved money buy using the factory harrness that came on the 5.3......watch gear heads for life on youtube he show which 4 wire to hook up .....just so u know in the future....
Yup, you definitely can, but a ton of work (days to rework a harness) so we opt to use new. PSI makes it too easy.
@@UNITEDBYTRUCKS thats cool that youtube channel i sent u he does the same to a square body.....plus check out this web site...LT1 SWAP.COM
I love the content brother! Much love man !
Thanks, man!
Niners whooped that ass!
what do you mean, that he used donor drive shaft!!! from what vehicle fits c10,
Driveshaft from the suburban
@@UNITEDBYTRUCKS does it have to be shortened or it fits perfect? I have a 03 donor suburban
to fit a lab c10 79'
Great info as always.
Thanks, brother!
Great job guys!!!!
Thank you so much!
I have a gmc 1997 sierra, i like it but it hhas high rpm, it goes pretty fast but something w the cylinder was wrong so its in the shop, it has a 4.3L vortec and im considering ls swapping it but i really dont know how much it is even after watching these videos
6k for labor around here. That made me execute it myself with the help of videos like this! 🤝 and bring Alex back asap
Yup, that's the way it is for us too. Only way to learn is dive in and get after it.
Whitlock Garage yes sir. I appreciate you
I cant believe people get 6,000 to do the swap? That's just labor?
Working mans restorations yes in Cali. Another grand for vintage air install
6k for labor alone is absurd!
Love Pecos! Congrats!!!
Gdmorning or gdnight this might be a old question. But new to the chevy game I bought my first 91 chevy silverado 4.3 v6 EF1. I understand I can go LS I know i need a LS motor cpu harness maybe trans. But witch motor mounts do i have to look up to buy. So I am able to run the LS.
You know, Omar, we've never swapped an OBS. I would start with Dirty Dingo and see if they have anything to LS swap an OBS truck (88-98).
Pecos is a really cool truck
No doubt about it!
What's yhe name of that kit that runs both tanks on tanksinc I can't find it
I want to build a 427 for my c10 but ls7 is way out of my price range. Is it possible to stroke a lq4 to 427??
Now that I'm unsure of. I think a pretty common bore/stroke is to 416 but unsure if 427 is attainable.
Should I go with 6.0 or 5.3 ?
Hi guys, I've heard that a 4.3 vortex engine is equivalent to a 350 engine less to cylinders. Is this true?
@Carlos p Yes it's true, the 4.3 has the same bore size as a 350, same oil pump, same water pump, same piston and rings, just has 2 less cylinders.
I have no mechanic experience at all and was wondering if it's possible for a average Joe to tackle a ls swap
It is, the only thing I think you might need some help with is tying the truck wiring harness into the LS engine and trans harness. Most everything else is nuts and bolts.
I have 3500 in swap on my 86 with a stage 2 cam
Sweet!
My old 70 short bed is getting a 350 swap! 😂
Heck yeah!
The should have had a 350 to begin with
Joshua Herpolsheimer it did, just swapping a new rebuilt 350 in
It cost 2k to do a budget 5.3 LS swap. 30-40 hrs for one dude easy.
Sweet!
@@UNITEDBYTRUCKS called it lol
I would be happy to replace my tired 350 with a 5.3.
It costs 2k if you cut corners, same with the 30 hours. Let me guess. Old fuel tank? Old exhaust? Old radiator? Old driveshaft? Plate mounts?
@@philistineau Cut corners lol
I'm around 10k in mine thats without having to buy a motor and trans! I did a lot of performance upgrades.
Pecos is cool truck
No doubt about it!
its pronounced PECOS (pay-cus) not PAY-COSE buddy! Pecos, TX! . sick truck, great videos ya'll!
Haha not in southern it isn't.
I’ve got a 1964 Impala. I’m wanting to do an LS swap but have no clue where to start. What LS motor should I go with and what’s gonna be the total cost when finished? Any help or recommendations would be greatly appreciated.
Man, that's a super hard question to answer. We like Gen 3 and 4 5.3s and typically end up with about $2500 in one aside from the cost of the motor and performance adders. Good luck!
Why leave the front bumper guards in that front bumper
Because they look awesome!
Love all your videos. Going to swap my 87 r10 soon. What about trans cross member ? Can the universal one from summit work or ? Thanks for sharing you guys are awesome. +
We use the Tejas trans crossmember.
just answered a question i had from another video. hahah. great content
Sweet! Glad to help.
Can you elaborate on the dual tank thing you mentioned at around the 2 min mark?
Great video and great ride👍🏻 love watching your channel keep up the good work
Thank you, Mark!
Love this series!! Been watching videos to find out how much this was lowered front/rear?
Thank you! It’s a 4/6 drop
Cant wait to ls swap my 85 gmc shortwide
Good interview
I'm pretty stickular 'bout it.." -TTR
He’s a dang mess
i got two local people that got trucks like yalls one have Ls 5.3 other got 454 which one do yall think i should get opinions from both of you
Depends on your goals, but if the swap was done right and you want longevity and reliability for long drives, go LS.
I’m assuming he’ll do Spal 2044’s with the Tejas shroud.
I believe so, yep.
Those little Bastards move a ton of air.
What kind of wire harness do u use for a sqr body?
PSI Conversion
I want to swap mine, but i don't even have a carport!
I got a quick question I have a truck like that TBI how much do you think I was being to rebuild the 700r4 transmission
A rebuilt 700r4 is legit. Usually around $750 to have one rebuilt to stock and it goes way up from there.
