Good video and a LOT of good info on doing a LS swap. Right detail and really good advice on saving money on a do-it-yourself swap. I have a 89 reg/cab s/b 4x4 that I'm looking at doing a LS swap on. It's my work truck and I need a lil more towing power.
Good info" some people might need to know about, steam port adapter, vacuum booster Port fitting, different fuel pump is pre 98 motor along with all rubber in fuel line to handle pressure, temp sensor 98 Camaro
I'm thinking ok doing this swap for my 90 k2500. Still thinking about it since I have an lm7 sitting in my garage for one of my muscle cars. I heard the transmission bolts right on. I was going to use a 700r4 for a nova just not sure if the 4x4 version would be the same for the trucks. I assume it will and then paired up to an fitech harness and computer should make this swap easier.
Mmh mine costed 1800 My vats delete and tune was 385 my wire harness i could've made but i work to much and never had the time it was 350 or 380 off ebay for it engine cost me 260 semi complete i just didnt have a air compressor
@@manuelramirez-rw5yt not really, from what I've read on fb groups, guys are finding 99 k1500s that come with factory 4x4 floor shifter and completely swapping it all over.
Very good video. Now I know that such a swap into an OBS chevy truck can be done for under 1K dollars with the parts you have mentioned in this video. I have the NV3500 manual transmission in an OBS chevy, but not too many videos are out there on such a combination with an LS engine. Can you advise what additional parts I might have to add to your parts list to make this combination happen? Thanks.
I’m sorry I don’t have much info on swapping with a manual trans. However I can point you in the right direction. Go join the 88-98 ls swap Facebook group. So much info
Dawson Copeland that’s not true at all, going from that 5.7/350 with trash fuel injection to let’s say a LQ9 later model 6.0 you’ll get 16/22 with a considerable amount more power than a 5.3 or 4.8 Also add in the extra power from the 6.0 that you don’t get from the 4.8 and 5.3 and the gas cost will be less than a 5.3/4.8 because you won’t be using as much power to lug that big ass truck around with a smaller engine. There’s no replacement for displacement. I’d throw a 6.0 in it over a 4.8/5.3 everyday of the week
I broke an intake bolt on my 97 5.7 2nd plenum I have access to a free 6.0 2005 GMC that my brother wreck I want to build this truck to mud 400s for hp should I 6.0 swap or fix/rebuild the 5.7?
excellent info! how about using the stock gauges from the donor truck and skipping the ECU flash costs? they seem like they can be made to fit on the OBS.
Endless Wishlist I might try this next year. one part not on your list is the flex plate adapter and its installation. maybe I missed it. what is the jegs ORY?
So how does the 4x4 work exactly? Did you use the stock 98 tranny harness or did you use the 5.3 harness to connect to the transmission. Ive done two swaps so far, both 2wd, but I’m getting ready to do my first 4x4 swap but I can’t find consistent 4x4 swap info, I’m either looking in the the wrong places or there isn’t much info out there. I have a rare 98 crew cab short bed that I daily for work, it has the push buttons 4x4. I’m taking a paid week off in November to do my swap.
It’s easy. I used the 98 trans. This truck also has the push button 4wd. The ls computer doesn’t control 4wd. It just has 2 pins that tell it that it’s in 4wd. The ls harness plugs right into the trans and controls it this year and a couple others.
@@EndlessWishlist ah alright I see so I’ll just use my stock trans and save myself some money. Thank you my man for the fast response, cleared up some headaches i had on the swap. I appreciate you helping me and other people with your knowledge on this.
Im thinking of doing a ls swap on my 1994 chevy blazer it orig comes with 4l60e trans but been doing my reserserch and that trans wont work so any ideas on what transmission i can use im buying a 2004 5.3 for the swap want to figure out what transmission and transfer case will work without doing to many mods and would love to switch over to a push button 4x4 please help thankyou ??????
Endless Wishlist thx for your kindness At first glance how can I tell if an engine is an LS and not a 305 or a 350? Your truck sounds like the way it should have when it left the factory I want my 1990 GMC to sound like that Got balls
@@EndlessWishlist Thats awesome; I'm in Ontario, Canada and there are a few people here doing complete stand alone LS swaps packages for people to LS swap their rides. All you need is a battery, fuel source and radiator set up to run. Plus of course mounts/kits for the specific vehicle.
When you said an adapter for the oil pressure sensor do you mean an adapter for the harness or an adapter for the factory 1998 oil pressure sensor to the 5.3??
The factory 98. The ls computer does care about oil pressure. So you have to adapt the factory 98 oil pressure sensor to the ls block so your gauge works inside
Holy crap! Dont oblong those bolt holes! Also if you dont use the transmission intended for it, you have to buy a stand-alone wiring harness which is way expensive" find the proper flexplate spacer and bolting it up is easy enuff, 4l80e is a beast! Be aware that is 1/2 to3/4 of an inch longer depending on what year 4 l60 it is.
I was wondering if you know anyone that can turn the 96 to 98 stock harness into ls plug and play hookup?so repin computer and hook up injector and rewire,(whatever else)?? If you know someone please let me know.thanks
I was wondering the same. Im going to Ls swap a 99 suburban and was wondering how the fuel system worked in this swap if anything needed modifications or additional parts
Because the 6.0 cam is bigger and it was just laying around. It didn’t come with flat tops, I put them in. And it’s my engine and I wanted eBay head studs. That’s why
Julio Cervantes I agree why would you only put a cam with 5 more degrees of duration, and Julio is right dude, they all came with flat tops. All the 4.8 and 5.3 from 99 and up have them. I would have just reused the used head bolts over ebay China crap
They did not all come with flat tops early 5.3 was dished piston 4.8 flat top. Some 6.0 came dishes piston some flat tops lq4 6.0 is dished piston lq9 is flat top piston the lq9 was the higher compression hotter motor from factory
Your rationalization on why you didn't include the cost of the engine and other stuff you bought when you titled the video "How much did my swap cost" makes zero sense.
12:53 you’re welcome
port nut no problem 👍🏽
Nice.
Clutch thanks
Lol thanks
Using the 5.3 harness and modifying it was a good call
Thankfully someone posts some helpful info.... you were very helpful. My biggest thing is wiring. But really want to do my 96

Thanks for the video.. helps alot, almost done with mine
do they keep the same transmision ? obs 1994
What about keeping it 4x4? My 94 has a floor shifter for the 4x4 just curious how would I keep that to work
did you ever get an answer to this i am wondering the same thing

How did you make your 4x4 to work with the harness I’m pretty sure yours would be the push button as mine 1997
Thats dope bro rn i swapped my 97 chevy silverado same as yours and all i need it wites to get it started
So my 94 4L60E won’t work behind the newer LS did I hear you say that right?
That's a great looking truck! Thanks for sharing this with us.
I paid $150 for a complete aluminum L33 with a harness and ecm.
Nick Mellon where?
Where the hell do you guys find these unicorns !!!! lol
A decent clean ls swap u spend 2k with motor with harness with everything needed labor aswell trans not included
What about with the transmission and labor for it too ( plus all the things the tranny needs )

Wanna do this exact same thing, drop a 6.0l in my sierra and that 5.3 is going into my k1500
What would I gain swapping from a 5.7/350 to a 6.0 ls swap on a 1999 k2500 crew cab...im looking for more mpg as i dont haul tow or race it
If youre going for mpg and done haul anything go with a 4.8 or 5.3. 6.0s are just slow gas hogs

hi there help i need a y pipe part number i look for no luck
Can you put a link to the parts
Hey I was wondering why did you 5.3 swap it? Is it worth it if you have a 5.7?
Definitely worth it. More power and better mileage and reliability.
Endless Wishlist did you put a different transmission? The 5.7 is reliable. But the mpg is better on the 5.3. Even the 6.0 gets better mpg lol.
excellent info! how about using the stock gauges from the donor truck and skipping the ECU flash costs? they seem like they can be made to fit on the OBS.
I have seen them retrofitted but it was a lot of work. And regardless the computer still needs to be tuned to have the vats deleted

How did it work ? I have a 95 k1500 4x4 that I would like to swap as well.
I am new to this so pls be gracious
I thought GM put LS engines in all their vehicles starting in 97
No?
No just the ls1 in 97. So the Camaro got it but the trucks didn’t until 99 in the nbs trucks.
Endless Wishlist thx for your kindness
At first glance how can I tell if an engine is an LS and not a 305 or a 350?
Your truck sounds like the way it should have when it left the factory
I want my 1990 GMC to sound like that
Got balls
Didier Mukendi, ls is fuel injection and no distributor. Thats pretty much it
You can tell if it has a distributor, or just look at the intake
Way to kick ass on your projects and think of the price it would be if you paid a shop to do all that work. 👍
Yea it would have been a lot more for sure
Does the factory 5.3 power steering pump fit the 98 obs. Lines and everything?
Yes they do.
Endless Wishlist Cool, I appreciate it man!
Did you use stock tranny. Any issues. Is the 6.0 same less or more.
Used the stock trans. And yes a 6.0 would be the same swap.
@@EndlessWishlist same add on parts too?
Yes. Externally the 5.3 and the 6.0 are the same as long as you get a 6.0 with aluminum heads. Don’t mess with the 1999-2000 6.0 with iron heads.
Noo a/c? All depends on your motor mounts
gaspar ortiz
There’s brackets available for under $200 that allow use of the truck’s original AC compressor.
what year 5.3 is that
2002
Can you put a link to the guy you got to tune your pcm?
m.facebook.com/bauerperformance/
If you had all the parts waiting (you didn't have to order anything and it was all at hand); how fast do you think you could do an LS swap?
Something I’d like to know. I love the obs , got same truck as him I’d love to modernize it
If I had everything I needed I could do it in a weekend.
@@EndlessWishlist Thats awesome; I'm in Ontario, Canada and there are a few people here doing complete stand alone LS swaps packages for people to LS swap their rides. All you need is a battery, fuel source and radiator set up to run. Plus of course mounts/kits for the specific vehicle.
When you said an adapter for the oil pressure sensor do you mean an adapter for the harness or an adapter for the factory 1998 oil pressure sensor to the 5.3??
The factory 98. The ls computer does care about oil pressure. So you have to adapt the factory 98 oil pressure sensor to the ls block so your gauge works inside
How to get in touch with the guy who did the computer for your swap
He has Instagram and Facebook. Bauer performance
Great info! Thanks
I have a 95 4x4 what transmission are you running? And will the stock transmission bolt up to the 5.3?
Stock 98 transmission. But yours is a little different than mine
Can you please link that eBay intake with the filter? I desperately need one.
It’s just a 99-06 5.3 intake.
I need the coupler and cone filter
Can you use 5.3 harness if you get your 5.3 bored over to a 5.7?
Yes
What oil pressure sensor adaptor did you use? is it just a thread conversion?
Yea converting the ls block to the obs threads. Mine was a 1/4 npt
Would it be easy to LS swap a automatic 94 with a 4.6 v6? My budget is around $2000
It will be harder starting with a v6
I know that you used an adapter but did you use the stock 5.3 flywheel
Yes
What adapter did u use
Will you be selling the truck back to your brother?
If he wants it he will definitely have first chance to buy it.
Can I do the swap in a standard transmission 98 silverado?
Yes
did you have to change the engine cross memeber?
No. Just motor mount adapters
Good shit man! Awesome info!
Did the factory transmission bolt up
Yup
Should be the same for a 69 c10r right? Great video
Bully Breaker no
A little more
What do you need to bolt up the stock 4l60e to the 5.3
Just oblong the holes on the flexplate where it bolts to the torque converter
@@EndlessWishlist Would the same thing apply on a 4l80e of a K2500?

5.3 is not an LS based engine it’s literally a iron block
It is LS based actually. It’s not a true ls aluminum block no but the swap it exactly the same. Maybe you are just missing the point.
