Thanks for sharing your build. It looks and sounds very good. Did you use the same transmission from the 4.3? Any modifications needed to mate the transmission to the LS? Since you made this video about a year ago, can you give us an update on how the vehicle is doing and whether you use it as a daily driver? And since the build, is there anything you would change if you were to do it all over again. Great work! Thanks again.
Is it possible to take out the 5.3 wire harness without having to cutting them ? I just bought a 2003 Tahoe for 950 and I’m putting the ls in my 93 obs .
Ive watched a hundred of these swap info vids. You sir are built for this. Im only half way through and cant get over how good its shot and how straight to the point you are. Appreciate you.
Great clean job on the swap! I just completed my 2nd swap as well on a 71 Chevelle (now in paint and body) as well. Since I’ve just been finishing small jobs on my first swap. Nice work! I subscribed and tuned in.🤙🏾

Thinking about eventually putting a 5.3 into a 1989 C1500 that currently has the 305 baby V8 with an NV3500. This helped a lot! Thanks! Also, where are you located? I live in Clemson and when you mentioned Greenville I was like HEY I KNOW THAT PLACE LOL.
Out of the swap stuff I’ve seen for these era trucks this was definitely the most informative. Plus including all the part numbers and other miscellaneous parts needed.
Appreciate you bro! I like the content and attitude and very informative. Planning on swapping a 4.3 NBS Silverado to a 6.0. I know it’s a different body styles but concept and parts needed are the same!
Man this definitely built my confidence, I just rebuilt the engine, having my 4l60e rebuilt. Like I mention on Facebook I had a V6 and had to do the same thing you did. Those bolts are hell to get to, but I got V8 clam installed now. I'm not using stock harness tho. I'm going with Holley Terminator X Mac and there 12.3 screen. I'm a customize my dash where it look stock....sorta Thanks KJ
Awesome video. I just bought a ‘98 with a 4.3, so that’s nice to know about the motor mounts. Also, I love your whole radiator solution. Factory parts FTW!
I want to do an ls swap but I want to change the transmission to a 4l60e will I have to change the driveshaft on my 4.3 or can the old transmission handle a used lr4 4.8?
You can reuse the old driveshaft if you set the motor in the right spot using dirty dingo adjustable engine mounts. Later model transmissions are leaps and bounds better than older transmissions, in my opinion.
Nice job man. I was given a wrecked 05 Silverado 1500 and it's got me thinking about putting that 5.3 into my '93 K2500. It would be a big power difference and that old 350 is pretty tired.
I got a 1990 RS with the V6 I'm looking at doing a 5.32 a 6.0 VA where's a good starting point besides buying engine and harness? Was it a complicated swap
What's going on KJ, blessing. I was just wondering, what mounts are those that you used to hold the radiator and fans? I need to cut the ears off my electric fans rn, but I need a bracket to mount everything. Thanks in advance for your time and response. 🍻
So you used the 6.0 clutch and pressure plate? I was told to use the 4.8 on my 88 5 speed also external slave and no luck on it disengaging the clutch ?
My 5 speed wasn't in the greatest shape when I started this. It still runs perfect but it's hard to shift at times, lately. Haven't looked into it to see whats causing it.
I have a 91 GMC that I wanna LS swap. Never been much of a car guy but always wanted to fix up an old car. Since this one was sitting in the driveway with a bad rear main seal it's gonna be my project. Shoutout from Rock Hill!
Its the same stuff in the picture at 2:55. NFW1050 flywheel. Luk 04-201 clutch which is OEM clutch equivalent. And 1377c throwout bearing. My nv3500 is external slave. Yours internal or external?
Cool Cars KJ will the nv3500 hold the 6.0 tho ? Bc I’m in the process trying to do a 6.0 swap on my v6 obs but idk if it will hold. And for the clam shells did you get a 3 or 4 bolt clam shell ??
I found this to be one of the most helpful videos on LS swapping an OBS . No bs, straight to the point. Thank you for doing this!!!
You broke it down bro so I 50 year old non mechanic could decipher it. Thanks Keep the video coming
Dude this video is beyond perfect. I’m looking to swap my 4.3 to an LS. My ‘96 looks like an old man’s truck, it’ll make a great sleeper.
did you ls swap it?

Is it possible to take out the 5.3 wire harness without having to cutting them ? I just bought a 2003 Tahoe for 950 and I’m putting the ls in my 93 obs .
Yes, it unbolts and unplugs. You do not have to cut it at all.
Appreciate it. I’ll be back for a lil more info once I get stuck again
Nice work! You came up with some clean innovative solutions.

What pedal are you using and where did you get the bracket
Using the pedal that came with the engine. Used an adapter from this guy:
i got it from this dude:
facebook.com/paul.seeman.5
Have you done an upgraded fuel pump hotwire kit for the integrated fuse box? I'm upgrading my fuel pump, but the factory wiring is too small.
I have not
This is badass! looks awesome and keep up the good work
hey bro where did you get the pedal bracket or did you fab it?

@@CoolCarsKJ thanks
Good information....
I love how u made the engine bay look clean looks stock
yup, tried to keep it nice and clean. just an old work truck ready to tackle any job, lol.
Not sure if it’s been asked but what headers are you running in the process of swapping my 95
It's been mentioned 100 times in the comments but they are Schoenfeld 1302LS1 Headers
Awesome video. I just bought a ‘98 with a 4.3, so that’s nice to know about the motor mounts. Also, I love your whole radiator solution. Factory parts FTW!
Are those upper radiator brackets stock? Mine has the plastic shroud thing going on. Just like to get a set like that for my obs.
Yes, stock on OBS vehicles that came with a 454...
Awesome video. Keep up the good work. I'm swapping in a 5.3 in place of a 4.3v6 right now
It will be a hell of an upgrade bro!
Did you have any problems with gas fumes after deleting the evap canister and putting a filter on the line?
Big time!
Kj love ur videos I’m in the middle of doing my 95 Silverado it’s just a process.
You can do it bro!!! See it through. What steps do you have left? 95s are the "bastard" year.
Nice job on the truck and video man, looking to do my 94 gmc short box 2wd also with a 6.0 l LS from a v-6
How is your project coming?
I have a 97 4.3 chevy obs and the transmission just gave out. I have a 05 Silverado transmission, can I install the 05 transmission into my obs?
Will this clutch and flywheel setup work with a 6.0?
The nv3500 will not hold up very long to a 6.0. Especially if modded. I wouldnt do it.
I need to LS swap my 94 Camaro for this spring! 💯💯💯
I want to do an ls swap but I want to change the transmission to a 4l60e will I have to change the driveshaft on my 4.3 or can the old transmission handle a used lr4 4.8?

So it turns out that Silverado has the all aluminum L33 in it. I've got to swap it now.
Got watch it again💯💯💯

Not that advanced yet bro. maybe one day.
Do you have the part numbers for the an fittings for the fuel lines
th-cam.com/video/b9vzbZ3hT8M/w-d-xo.html
Did you use the stock transmission? If so how does it hold up?
Yes, it's still kicking.
Is it necessary to buy a low profile oil pan for the chevy OBS???? I have a 5.3 out of a 2005 Tahoe on a 1996 obs.
No, not if the vehicle is stock height or slightly lowered
thanks!!
Whats up bro nice video.. is there any way i can contact you for some question
Instagram... @cool_cars_kj
Great video kj! I got a 98 4.3 I was thinking about doing the same. Did you change your gauges? The only difference is I have an automatic trans.
So you used the 6.0 clutch and pressure plate? I was told to use the 4.8 on my 88 5 speed also external slave and no luck on it disengaging the clutch ?
What did u do with the a/c ?? Is it working!!how did u connect it to the old style
I don't have AC on it yet. Hopefully soon.
Why did you need it tuned ? Was it because the aftermarket ecm?
When you change specs (like adding a cam) you have to get it tuned.
What v8 mounts can I use ? I also have the 4.3 mounts
Mounts from any obs that had a v8. Just select that when searching
We’ll explain , what starter did you use
The starter that came with the donor engine. The ls starter works perfect
Quick question bro that clutch the brand is luk right ? Im trying to do a swap and well just wanna be 100% sure
Yes I used Luk
I’m getting ready to do the swap on my 93 except I’m probably going carbureted. I’ll probably just take the 6.0 out of my foxbody
Aye boss do you have a link for that motor mount you used?
amzn.to/3wnI37m
I belive I bought a black truck bed from you the truck it went on I’m getting ready to do the same too
Good stuff, if so! Hope your build is working out!
I quess one of the benefits of living out in the sticks is you don’t have to worry about emissions but I’d definitely need A/C
How is it holding up I’m doing the exact thing next week
My 5 speed wasn't in the greatest shape when I started this. It still runs perfect but it's hard to shift at times, lately. Haven't looked into it to see whats causing it.
