Great video. I've got a V6 '99 Silverado that I want to hang on to but wishing to replace the engine with a crate motor long block V8. Have done some VW and Toyota engine swaps years ago but this is definitely a bigger job. I'm getting schooled by you guys. Thanks for this preliminary education. Much needed. Lotta prep required.
u need a setup from any 5.3 or 4.6 chevy thats 99 02 nothing newer or its not a direct swap and make sure u get a non flex fuel setup to so u dont have to have it tuned
Getting ready to pull a knocking 4.3 out of my 04 hopefully this video and others will help my dumbass finish it, it’s been 15+years since I’ve pulled any motors good video.
I’ve done this job and many others like it and I will say that you do not need to remove the fenders. If you have a separated motor and transmission, you can drop in the motor over the radiator support. Removing the fenders and just sliding a motor in is very nice, but with how simple these motors are, removing the fenders is often not worth it. Especially when the body lines Are already nice and straight, they often don’t go back on the exact way they were. Aside from that, great video and nice truck👍🏻
Hey, appreciate it and thanks! I’m not sure if I mentioned it on the video but we were changing some other items aside from the swap so it just seemed easier to remove it all, that way it also helped record better angles for the video.
Did the fuel gauge reading backwards? I did the v6 to v8 swap and noticed my fuel gauge was not reading properly and my battery light is on. Also on the gauge I got a service brake booster message which it didn't have before
No bro I haven’t ran into that in any of the swaps my only suggestion is check the grounding wires for the battery light. The fuel might have the signal wires backwards you might get away by switching them around. And check that sensor they take in the booster that actually broke on mine and I just ended up replacing the booster.

Super informative. I have an 06 4.3 Silverado that’s dbc and I’m swapping it with an 04 5.3. I have the harness, ecu, and tac module etc... the 5.3 I have has fuel and return like yours but my 06 is return-less. Could I put an 05-06 intake on the 5.3 to convert?
You can do that and get the 05-06 intake. You can also get a bit better power with a nnbs intake with adapter for the throttle body. As well you can buy a plug for the return line it runs about 25-30 bucks and problem solved without buying any more fuel rails or intakes.
I got a question bro, I did the same swap to my truck, and it's not tune yet cuze I'm confuse with the pedal and throttle body, did the pedal can send signal to the throttle with the key on even if it's not tune yet? Or will the tuner fixed?
As long as u got a tac module that goes from the main harness then down to the pedal it should work if not you need it. Only if the throttle body is electronic. Also the gas pedal does not go connected straight to the throttle body it needs the tac module to function properly.
@@proyectosloscarnales4512 lo tengo todo carnal esta conectado y todo lo mismo como el swap que hiciste, pero al momento de pisar el pedal no manda señal al throttle quiero saber si es por q le falta el tune

I just got a 04 V6 clean ass truck but it needs a V8. Some people use the older blazer computers but others use the computer that came with the donor engine. Whats the difference i see alot vids that are different. Thanks if anybody answers
If u get a donor engine from 03-06 (drive by wire) the computer and wiring that come with it should be a direct fit to your current fuse box and you would just need a tune to be out and driving. The older engines 99-02 (drive by cable) have a different setup and you would need to move some wires around to get it to fit on your current fuse box.
@@proyectosloscarnales4512 O got it. Thanks for the info I'll probably go with the 03-06 setup then still deciding what V8 i want, My buddy is a 6.0 guy in the square bodys, he gets those engines frequently some how
Hey wuts up bro. Great video 👍🏽 i did the whole efan conversion too just how you did it. Computer was tunned for those efans but my efans still dont turn on. Temp has past a little bit after 210 and no efans. Any suggestions?
Depending what harness if it’s oem make sure the relays are good and the power and ground are hooked up too not just the green and blue wires if it’s aftermarket trace the wires make sure u got a good power source and ground on both ends
I’m not too sure I imagine it’s switching over all the suspension like control arms and front differential mount and such but Ive never done it. What I do know is the transmission can just get switched over from 4x4 to 2wd just switching the tail housings and getting rid of the transfer case.
Hey Bro quick question so I got my 6.0 engine harness tac module pedal ecm and I watched your video that pretty much explained everything the only thing I’m lost is on how to hook up the fuel lines the swap is going into a 03 Silverado and the swap is from an 05 Denali
On the 03 if it has a single fuel feed and the intake does too it just plugs in you will just need the fuel line removal tool to pull the fittings apart and clip into the new ones
These are the fittings I ran the 5/16 is for return line the 3/8 is for the pressure side 165056ERL 5/16 to -6 AN adapter 165006ERL 3/8 to -6 AN adapter 658490 Russell 1 ft -6 hose (2x) 644123 Russell 3/8 push lock 644113 Russell 5/16 push lock
i know you did this swap years ago, but i have a 2003 silverado single cab 4.3l drive by cable, swap in a 99-02 6.0 wire harness dont line up with under hood fuse box, the plugs are pinned out differently. should i convert to drive by wire seeing its a 03+ truck?
Yes you’re going to need different items like the harness and throttle body electric pedal and the module for it. Amongst other sensors and the pin in the bottom of the fuse box should line up the same.

Can i use a blue/red harness motor in a 2006 v6 Silverado that is already drive by cable? I have the motor, harness and ecu out of a 2001 Silverado 4.8
The difference is where it plugs into the fuse box. U can see a black square-ish connector and compare the wires (colors) they won’t line up and then you’ll need a electrician it’s a way bigger hassle than just getting the correct one you need from the beginning.
@@proyectosloscarnales4512 ok because i also have a blue/green harness but alot of the sensor plugs are different on the motor and some arent even there
If u plan on using that engine u will have to change those sensors off the back I know the oil pressure the a/c and oxygen sensors are different also your throttle body bro. That’s y I say get the engine swap for the correct year to make it all easier down the line.
There is a TAC Module that plugs into the engine harness and goes bolted to the firewall by the booster, and then it has a small harness that goes from the module to the gas pedal. You can briefly see it at 16:53 before we actually bolted it to the firewall and installing the pedal.
Hey bro I’m currently doing a v6 to v8 swap on my 2000 sierra and I’m putting an 03 5.3 with electric pedal but it won’t start do I need tune first or can I still make it start with no tune?
If doing oem harness you need the drive by cable harness not the drive by wire with electric pedal. Unless your doing a complete swap harness you may have the wrong one now. And the computer needs to be tuned to turn on and stay on otherwise it will just crank and maybe come on for a second then shut off alone
I have an 05 Silverado I’m swapping, I have the early style dbw from an 02 red and blue pcm with all plastic tac. Can I use that setup or does it have to be 03-06 green and blue harness?
You need the new harness and ecu look at the small black connector you pull from the bottom of the fuse box the red/blue harness will not match up the wire sequence and the red/green will

Man I watch you videos and was trying to find this one......I need to know what's a good cam for street driven 4.8 ls that's better than oem...wanted a little more power...needed to know what kind of cam springs and lifters....please get back with me.....thanks anyone
If you want to keep it a daily driver it might be good to go with either a stage 1 or 2 cam kit (cam springs and seals) from BTR or Texas speed. Those cams don’t require a stall converter and are mild enough to where you don’t need to swap lifters pushrods and such.

You can shoot me a message on IG @ JulioPLC1 and it would take a little more time but you can go to BP automotive and in their website they have a swap harness and different kits that would include an ecm so you can swap it into anything. With that you would just have to wire in the gauges yourself and the transmission for the neutral safety switch and the reverse lights. You get a pedal and ecu with a baseline tune to start up and take it to dyno tune yourself later! Shoot me a message i would love to see the progress on this!
To the bottom of the fuse box when you take off the cover for the fuses and pull up the box you can see a black square connector with a 8mm holding it down just that and the other ends it leads to with clip connectors

Yea bro the motor mounts are the same but just be aware that the brackets that actually go on the frame to hold the motor mount won’t work from a Yukon you need Silverado v8 ones for the swap
That’s what I did to mine but with a 5.3. Aside from the actual harness you need to get for a 99-02 you will need the throttle body, fuel injectors(maybe the fuel rail or even a whole intake from a 99-02 to make it easier), oil pressure sensor, and the a/c system for your year.
this is a 03 plus swap anyone who has 99 to 02 will need a setup from 99 to 02 and get non flex fuel and anyone who says u need a anti theft flash u dont u just need a key relearn and the truck will run 99 to 02 is red and blue plugs and cable driven throttle body and the 99 to 02 4.3 throttle cable will go right to the 5.3 alot easier of a swap if u ask me

@@andhonialvarez2999 I'll also be taking the heads off of our 1999 Silverado with a 2005 5.3L swap. I have to put the ported 243 heads on and set aside the 862's. But when the heads are off I have to go in and fix the fuel line connections on the hose sections that they added because they didn't tighten them down i guess. I already had to replace one of the upper/intake side fittings because they had the metal fuel line bent a little causing it to leak and they chewed up the threads on the AN fitting somehow. It really is easy though bro. I could order lines for days and fittings and do these swaps all day long. I can even do the 4L60E to 4L80E swap in these trucks really easy with the exception of needing a new driveshaft made and a custom tune.

It sounds dope I havent looked much into them since that’s around the lt engines now and it’s a different setup but good luck on the project enjoy it and take lots of pics to go in the memory bin!
Everything still works with the original dash harness. In the video you can see the v8 engine harness plugs into a TAC module and that has a small harness that goes through the firewall and plugs into the electric gas pedal

If it’s an 02 u can use the harness and ecu from the engine u get and just pay around 100 bucks to get it flashed to work for you. In the process you can shoot me messages on my IG @JULIOPLC1 to see your progress bro! 👍🏽
Super informative. I have an 06 4.3 Silverado that’s dbc and I’m swapping it with an 04 5.3. I have the harness, ecu, and tac module etc... the 5.3 I have has fuel and return like yours but my 06 is return-less. Could I put an 05-06 intake on the 5.3 to convert?
You can do that and get the 05-06 intake. You can also get a bit better power with a nnbs intake with adapter for the throttle body. As well you can buy a plug for the return line it runs about 25-30 bucks and problem solved without buying any more fuel rails or intakes.
You just need a return less fuel rail 05+
In what part of Texas are you guys located ?
I really need help with an LS Swap that I did my self , I’m so frustrated at this point 😢
I have a whole truck 05 that has a 5.3 that I’m going take out and put in a 2000 v6 so I just have to grab everything I need form the 05 truck right
I got a question bro, I did the same swap to my truck, and it's not tune yet cuze I'm confuse with the pedal and throttle body, did the pedal can send signal to the throttle with the key on even if it's not tune yet?
Or will the tuner fixed?
As long as u got a tac module that goes from the main harness then down to the pedal it should work if not you need it. Only if the throttle body is electronic. Also the gas pedal does not go connected straight to the throttle body it needs the tac module to function properly.
@@proyectosloscarnales4512 lo tengo todo carnal esta conectado y todo lo mismo como el swap que hiciste, pero al momento de pisar el pedal no manda señal al throttle quiero saber si es por q le falta el tune
Do you know exactly what adapters and line I’ll need for the fuel set up I have a 07 classic I’m doing a 04 6.0 swap to
Hey bro we’re doing a v6 to v8 but we ran in to trouble with the gas line hope you can help me out
what are your issues
Okay got a question I did a swap exactly like yours but now my instrument cluster, door locks and my OBD2 won’t communicate and try we’re working just fine before the swap? Any ideas
Did the swap and used the same v6 4l60e but flywheel doesn’t line up
I just got a 04 V6 clean ass truck but it needs a V8. Some people use the older blazer computers but others use the computer that came with the donor engine. Whats the difference i see alot vids that are different. Thanks if anybody answers
If u get a donor engine from 03-06 (drive by wire) the computer and wiring that come with it should be a direct fit to your current fuse box and you would just need a tune to be out and driving. The older engines 99-02 (drive by cable) have a different setup and you would need to move some wires around to get it to fit on your current fuse box.
@@proyectosloscarnales4512 O got it. Thanks for the info I'll probably go with the 03-06 setup then still deciding what V8 i want, My buddy is a 6.0 guy in the square bodys, he gets those engines frequently some how
A 6.0 is a really good way to go and you can usually find it in a old work truck or van at a wrecking yard

Hey wuts up bro. Great video 👍🏽 i did the whole efan conversion too just how you did it. Computer was tunned for those efans but my efans still dont turn on. Temp has past a little bit after 210 and no efans. Any suggestions?
I also repinned it too
Depending what harness if it’s oem make sure the relays are good and the power and ground are hooked up too not just the green and blue wires if it’s aftermarket trace the wires make sure u got a good power source and ground on both ends
I have a 99 silverado 4x4 with 5.3 donor truck and have a 02 silverado v6 2wd. can i swap the 4wd also?
I’m not too sure I imagine it’s switching over all the suspension like control arms and front differential mount and such but Ive never done it. What I do know is the transmission can just get switched over from 4x4 to 2wd just switching the tail housings and getting rid of the transfer case.
Hey Bro quick question so I got my 6.0 engine harness tac module pedal ecm and I watched your video that pretty much explained everything the only thing I’m lost is on how to hook up the fuel lines the swap is going into a 03 Silverado and the swap is from an 05 Denali
On the 03 if it has a single fuel feed and the intake does too it just plugs in you will just need the fuel line removal tool to pull the fittings apart and clip into the new ones

Yes you’re going to need different items like the harness and throttle body electric pedal and the module for it. Amongst other sensors and the pin in the bottom of the fuse box should line up the same.

Can i use a blue/red harness motor in a 2006 v6 Silverado that is already drive by cable? I have the motor, harness and ecu out of a 2001 Silverado 4.8
No. The v6 is a drive by cable but u have to change the harness to a blue/green and add the electric pedal and tac module for that year
@@proyectosloscarnales4512 even if i have the ecu and complete harness to go with the 4.8?
The difference is where it plugs into the fuse box. U can see a black square-ish connector and compare the wires (colors) they won’t line up and then you’ll need a electrician it’s a way bigger hassle than just getting the correct one you need from the beginning.
@@proyectosloscarnales4512 ok because i also have a blue/green harness but alot of the sensor plugs are different on the motor and some arent even there
If u plan on using that engine u will have to change those sensors off the back I know the oil pressure the a/c and oxygen sensors are different also your throttle body bro. That’s y I say get the engine swap for the correct year to make it all easier down the line.
Great vid lots of info! Do you know if the swap process is similar for an 09 Sierra?
How do you install the electric gas pedal, switching from v6 to v8 5.3, I know how to do it from the inside just where do you hook it up from
There is a TAC Module that plugs into the engine harness and goes bolted to the firewall by the booster, and then it has a small harness that goes from the module to the gas pedal. You can briefly see it at 16:53 before we actually bolted it to the firewall and installing the pedal.
Are there any real differences besides the obvious when doing this swap on a manual truck?
Not really aside from the obvious like harness and fuel if you plan on keeping it manual you might have to look into a flywheel and clutch to work out
Hey bro I’m currently doing a v6 to v8 swap on my 2000 sierra and I’m putting an 03 5.3 with electric pedal but it won’t start do I need tune first or can I still make it start with no tune?
If doing oem harness you need the drive by cable harness not the drive by wire with electric pedal. Unless your doing a complete swap harness you may have the wrong one now. And the computer needs to be tuned to turn on and stay on otherwise it will just crank and maybe come on for a second then shut off alone
Great video. Gracias!
I have an 05 Silverado I’m swapping, I have the early style dbw from an 02 red and blue pcm with all plastic tac. Can I use that setup or does it have to be 03-06 green and blue harness?
You need the new harness and ecu look at the small black connector you pull from the bottom of the fuse box the red/blue harness will not match up the wire sequence and the red/green will
QUESTION!! Thanks in advance. I have a 2007 sierra classic v6.
And i have a 2001 5.3 tahoe flex fuel complete. Should the process be the same? Great video!!! Subscribing!!
I have a 2000 GMC Sierra with a 6.0 , it’s drive by cable im having issues with it turning on and back off like the anti theft is in it . Is there any help or advise you could give me ?
Honestly just make sure you get the computer tuned or programmed (VATs delete) properly it’s what it sounds like
@@proyectosloscarnales4512 yeah because the ani theft system is not even on anymore and it cuts off right away
did you keep v6 torq converter/flexplate?
We did use the flex plate from the 5.3 the torque converter and trans was the one from the v6. The transmission lasted a while but was upgraded after it gave out.
Man I watch you videos and was trying to find this one......I need to know what's a good cam for street driven 4.8 ls that's better than oem...wanted a little more power...needed to know what kind of cam springs and lifters....please get back with me.....thanks anyone
If you want to keep it a daily driver it might be good to go with either a stage 1 or 2 cam kit (cam springs and seals) from BTR or Texas speed. Those cams don’t require a stall converter and are mild enough to where you don’t need to swap lifters pushrods and such.
@@proyectosloscarnales4512 doing that will the stage 2 give the 4.8 a little more horsepower.....then what type headers wil be good after I pick a cam.? I was really wanting to go with stage two...what's the difference between the 2
What’s up man have problems with security lock after my swap did the same swap what do you recommend?
have a tuner check out your ecu aside from making sure it has disabled the anti-theft make sure the computer is good and not locked
wow , very informative video , very nicely done bro ! thanks Proyectos Los Carnales , i have a 2003 Silverado with a 4.8 and i almost bought this 2013 6.2 Escalade motor with tranny , im guessing with what you said , it would not be plug n play ? how difficult would that be ??? and if i can get your e-mail , thanks
You can shoot me a message on IG @ JulioPLC1 and it would take a little more time but you can go to BP automotive and in their website they have a swap harness and different kits that would include an ecm so you can swap it into anything. With that you would just have to wire in the gauges yourself and the transmission for the neutral safety switch and the reverse lights. You get a pedal and ecu with a baseline tune to start up and take it to dyno tune yourself later! Shoot me a message i would love to see the progress on this!
Hey my v6 harness connects into firewall. How did yall got about this?
What year is it?
I cant get the cruise working in mine.
I haven’t messed with the cruise control on the swaps I’m not sure what to tell u on that bro
So you can use red and blue engine harness on a 2003-2006 nbs

orale guey, que rayos, Vive Yustone!
How did u hook up the v8 harness
To the bottom of the fuse box when you take off the cover for the fuses and pull up the box you can see a black square connector with a 8mm holding it down just that and the other ends it leads to with clip connectors
Buena la clase carnal gracias
De nada 👍🏽
I'm trying go get my truck done by yall honestly

Did u not give 1/8 spacing for the converter
No we ran it straight off from v6 to v8 and the tranny ran fine for about a year under decent pressure

Yea bro the motor mounts are the same but just be aware that the brackets that actually go on the frame to hold the motor mount won’t work from a Yukon you need Silverado v8 ones for the swap
Did u tune it before starting it bro?
Just a base tune to let it turn on after the swap and erase emissions codes

No just the engine/trans harness that plugs into the fuse box in the engine bay.

That’s what I did to mine but with a 5.3. Aside from the actual harness you need to get for a 99-02 you will need the throttle body, fuel injectors(maybe the fuel rail or even a whole intake from a 99-02 to make it easier), oil pressure sensor, and the a/c system for your year.
@@proyectosloscarnales4512 thanks for the info
this is a 03 plus swap anyone who has 99 to 02 will need a setup from 99 to 02 and get non flex fuel and anyone who says u need a anti theft flash u dont u just need a key relearn and the truck will run 99 to 02 is red and blue plugs and cable driven throttle body and the 99 to 02 4.3 throttle cable will go right to the 5.3 alot easier of a swap if u ask me

But when the heads are off I have to go in and fix the fuel line connections on the hose sections that they added because they didn't tighten them down i guess. I already had to replace one of the upper/intake side fittings because they had the metal fuel line bent a little causing it to leak and they chewed up the threads on the AN fitting somehow. It really is easy though bro. I could order lines for days and fittings and do these swaps all day long.

Everything still works with the original dash harness. In the video you can see the v8 engine harness plugs into a TAC module and that has a small harness that goes through the firewall and plugs into the electric gas pedal
