What is the part of the swap that you know the least about? OBDII vs OBDI, electrical, fueling, etc etc
Fuel pump options would be a great topic.
Turbo hot side design. LOL. I’m not sure if I’m going to have it go in front of the engine with electric fans or around and up through the passenger side with mech fan. I’d like to keep my mech fan I think.
electrical . Eewww
What's the best manual transmission to use for the ls2 ?
Something heavy duty that can handle this heavy truck
@@user-jk3ge4xc4b people use t56 or tr6060
If you want the best transmission for hp and weight, t56 magnum
You do NOT need to change the engine crossmember. If you get the right mounts, the pan clears properly. The Advance Adapter adapter plates with factory clamshell mounts work mint for example. The later LS engines do not have a TAC module, so folks need to check the vehicle it's coming out of to see if that donor uses the TAC module system. Some radiators on the LS HAD the upper hose that goes to the driver's side depending upon the water pump inlets. What you spoke of is "correct" based on your particular usage/setup, it's not 100% correct.
YES! I knew there would be knowledge in the comments. Thanks!!
Lots of manufacturers make motor plates these days for LS swaps for almost any application! It’s crazy!! Back to square body Chevy/GMC you are correct in not having to modify or replace the cross member, although the LS series of motors have rather wide oil pans and it is nice to have the extra clearance with aftermarket cross members like Off Road Design.
Well I know what grandpa felt like when he went from model T to family sedan in say the sixties. I'm 73 and bent wrenches most of my entire life.... and now crippled living through the net like yourself sharing. I just know if I could move my arms that I could do one of these. I get confused on the meaning of LT or LS or other said blocks and not sure that explaining will stay in this fraction of what I used to be. I know when I am listening to someone who knows and gets it done so new subscriber
Definitely looking forward to this series ! 🤠
You're only "stuck" in quarantine if you're compliant. Do Not Comply. Solid ls info.
Thank you for posting these. Good Info here..
Perfect timing because my motor just lost 2 cylinders last weekend . Now I have to make my decision
This is excellent content -- well done.
what a awesome video!!! best video regarding ls swaps ive seen.. very straight forward and gave me the courage to do this...
That’s awesome man! Go for it! There is no problem that you can’t bang out with patience and persistence.
My blazer has the exact same paint job/patina, same front end qnd same interior!!! This is nuts!
This is exactly what I needed to see, thanks for the great info. I'm ready to dive in.
heck yea. Stokes me out to hear that. Just take your time, plan ahead and expect setbacks. But you will knock it out in the end!
@@MerricksGarage Appreciate that. Subscribed, it's easy to see all my questions can be answered here.
Enjoyed your video I’m in the process of putting a N Ls Gen 3 in my 75K5 Blazer really looking forward to better performance it will give keep the great videos coming
Its not even the performance, its the overall drivability! Its a lot of fun.
Gonna do this swap this summer in my 95' G20
Great video as always Jason Bro @MerricksGarage
Great video man I'm looking forward to all the info.
Glad to hear it!
I have a 87 K30 Army truck that I Bought with a 350SBC so I did the most sensible thing and swapped it for a LQ4 6.0 and a 4L80e. All with Terminator X. I Love it, it is a Bit of a Sleeper. BTW, I just used Dirty Dingo Motor mounts and SBC clam mounts. all factory oil pan and crossmember. But I also think that my K30/K20 frame is a bit different then a C10 or K10. It has 1 ton axles from the factory.
Amazing content sir love it I liked and subbed keep it coming
Thanks for the sub!
the burban looks great. i hope you do a duramax swap on it. that would be a sweet overlanding rig. looks like your growing a nice Quigly down under mustache
It’s my quarantine mustache! It looks ridiculous but is sooo awesome lol.
Great Video!
great mechanic!
Great video!!! Thanks!
You bet!
Its not had most people tell you how hard it is most dont know what there doing that's why it's called Competition beleave me it's just nuts and bolts with some wire fuel and work ! So I say go for it injoy the conversion! I'm on my 23rd one!!!
Thanks for the words of encouragement! I've got a first gen K5 and shes getting an LQ4/4L80 combo I picked up. Think I might Carburete it for nostalgic reasons. I guess I cant totally let go of the old ways, haha!
A carb’d LS is actually pretty cool.
FI tech makes a fuel injected carb looking system and once the breather is on, you can't tell the difference.
$1500 to run carburetor?!.
great video, thanks
Glad you liked it!
Yes sir love your style ,content, and knowledge thanks for all that ....plus u have integrity and manners not cussing and acting like a damn fool like a lot of them thanks again love your stuff keep it coming please ? How about obs ls swap stuff and process and parts list with links where you get the parts 🤔 👀 😉
thanks man! I do really try and keep it family friendly. Gotta raise up the next generation right!
Looking more and more like I'll gut my 03 2500 Sub to swap in the LQ4 6.0. Look forward to the Series! I wasn't thinking about the pedal assembly...
Carl, I have a feeling that before you are done, you will have a four linked LS swapped fire breathing K5 Blazer
@@MerricksGarage Haha!!! We are never "done"! Have a great one James.
Great video very informative
Glad it was helpful!
factory crossmember will clear oil pan if you use 350 to ls mounts. theyre 30$, they drop right in, clear everyting and if youre using the original transmission the driveshaft will still fit.
Good info. Is there a video on how to adapt a 4l80 or 4L60 transmission and keep the 4x4. Trying to ls swap a 1975 blazer but can't seem to find how to integrate a newer trans too with 4x4. Thanks
Holley has a complete swap kit. If I did it, I would stay carb. No efi, keep it simple. Great video.
The Holley kit is killer. I’ve done a few now and still the best option out there in my opinion
Great info thanks. I have a complete running/driving donor 2500HD. I’m going to see how much I can use other than the push button operated transfer case.
yea do not use those push button. They quit working right when you need them!
Merricks Garage I’m going to run the stock 241.
I recently swapped my 350 to 305 and maual to elcetric carb on my 1980 chevy blazer from a 1984 3/4 ton chevy and It's been little different issues to try to get my engine sounding and running just right...but I def could use some of these tips....uuugghhhh love my blazer and really want to just rebuild my 350 and put back in....but man it can suck at times...lol thanks for video
no problem! This is why these trucks take so long to get right. It is like tuning a piano.
305 was a joke motor ive only seen one worth its salt. 350 all the way
I’m excited to swap my 76 Jimmy. I have a LQ9 sitting in my garage waiting on more parts. Given the old small block has been a trooper I figured it was time to retire it before it strands me. I’m still undecided on a trans. My Jimmy has a TH350 in it and I have a TH400 and 205 combo. What is your thoughts on a 4l80e? I have seen some people say it’s worth upgrading when doing the engine swap. I don’t want to try and figure out how to use the TH350 because of the lockdown cable and the one in my Jimmy leaks for every seal at this point anyway.
I just dropped $300 on a 4 core aluminum radiator last year when I threw together a big cam 355... clearly threw it together to quick 😂
thinking of ls swapping my 77 k5 but i lost my screws to my crossmembers....🤦🏿♂️🤦🏿♂️ so i’ll probably have to get some custom made
Just spent all day today in my quarantine treating my 83 K5 by installing an 02 LQ4 out of a Denali with a 4L65E transmission and mated it to my np208 transfer case. I used the dirty dingo motor mounts and they allowed my engine and transmission to slide it into the just the right position where I didn't have to change my Drive Lines or remove my motor crossmember.
Awesome. When I did my swap the dirty dingo mounts were having some issues. The steel they were using was too thin and was bending. The diy4x are waaaay burly
@@MerricksGarage good to know. I hope i didn't get a bad batch. They seem pretty robust.
The Dirty Dingo mounts are awesome!!! They have had some changes in designs.
@@dukeloster923yeah they seemed pretty well made to me.
I have a beautiful k5 blazer all restored thats on my list for sure does the transmission and engine bolt up ok
yup, there may be a top bolt on the trans that isn't used in certain models, but the 4L60 series is pretty much the same case as a 700R4
Subbed after 1 min in love ya already bub
thanks homey!
I was trying to find a playlists of your LS swap videos. Could you point me to the right direction? I've got a 73' K20 I'm about to start on. Thanks!!
Might just do this I have a fully functioning 2002 suburban 5.3l 2wd that I got for 1500$ might just look for a roller square body suburban 4x4 and swap engine n tranny
Sup dude u didnt cover the transmission crossmember? Make your own or who did you buy from.....
Love the starch!!!
Ha ha. It’s my quarantine stache!
Do you reused the old break lines and fuel lines from the truck? Or do I need to used the one from the donor
Can you do a video on what tools will be needed . Must have tools, etc…
Go look at my snapon and Milwaukee videos. Cover a lot of that.
Another benefit of the efan is when you get to flexing over objects your mechanical fan can bind up.
yea, the downsides of the efan is the noise. They are LOUD. Add my trans cooler fans to the mix and it is like the truck is taking off! But my temp control has never been a problem!
@@MerricksGarage Yea they can be loud some E-Fans utilize a variable speed controller to slow it down or speed it up depending on temperature level. Also you can put them on a timer or manual override to run them say you start running hot on the trail. Also with E-Fans you can get full airflow even at low engine speeds great for crawling. Some trade offs but I prefer E-Fans if the electrical system can handle it.
yea I have mine on a switch so I can turn them off when I want. They really don't need to be on when I am on the freeway cruising and when I pull into parking lots etc they can be super loud and I will sometimes turn them off
Will the Tach Module/ aftermarket harness let it talk to the factory tach?
I am about to swap my 1987 R10 Silverado with a 5.3L out of a 2003 GMC Yukon. How do I go about tricking the computer once I remove the emissions? Thanks in advance for any details you can share.
Do you need to swap oil pans after using the ORD crossmember?
I'm getting ready to drop a '06 6.0L/4L80e into my '90 V1500 Suburban and I have the donor vehicle and I want to use the donor wiring harness. What do I need to keep off either vehicle and can I use the '90 trans crossmember or do I need an aftermarket one?
DBC is king cost wise and can't go wrong with it
yea, it is easy, but mounting options for DBW are killer
What transfer case did you use I’m struggling with mine with the original transfer case not having a transfer case speed sensor
241 with SYE kit. VSS on output
If you do the motor mount adapters you do not have to replace your cross member at all I have A 6.0 in my 74 K 10 I had no problems with the LSX adapters
I have a 1987 4x4 sm465. I have a 2003 donor truck 4.8 what extra do I need.
Did you use stock a/condencer
The transfer case from the 4x4 LS trucks outputs on the driver side..... will I be able to use my passenger drop np208? I have a set of chevy dana 60/14b that I bought last year and really want to swap it...
yes
Do I need to change my drive shaft in my 94 blazer
I have a 95 k1500 4x4 w a 5spd. Would a ls bolt up to my transmission? Liked your video a lot keep em coming!!
I am sure someone makes an adapter. Google your trans model and LS and see what comes up
Do you have a NV4500? Advanced Adapters has what you need!!! Great USA based company! Give them a buzz +18003502223
That's odd..... I didn't have to replace my crossmember when I LS swap on my 90 k5. I also Cummins swapped my 87 dually and kept the stock crossmember.
yea, there seems to be some variation in oil pans
What did you do for a CA compliant exhaust and evap system, I'm currently trying to work out a 2004 LM7 into a 1997 Silverado in So cal.
My truck is smog exempt. I swapped the frame out when I did all the links. The trick is to start with a donor vehicle that you can pull EVERYTHING off of. Piecing it all together from junkyard can be possible but it all has to match. Like same exact Evap canister.
I just want 6.0 and a t56
How did you pass the referee with 4 o2 sensors. The stand alone wiring harnesses I have found only use the upstream sensors not the downstream sensors
These are both smog exempt. Diesel and pre smog
Hey merrick can you do another rig walk around of the durablazer again please
It’s on my list. I wanna do a drag race with Nick ha ha
I agree!! Get some DuraBlazer!!!
@@dukeloster923 you in your SAS 1500, me in the K30Blazer, Nick in the Durablazer. Drag race? I'm down!
I am in!!
Do recommend the electric speedo or the cable speedo !?
Electric. GPS even easier
Very very torn between keeping the 6.5 diesel optimizer out of a hmmwv in my K5, or going LQ4.... the 6.5 is putting out stupid torque, but needs a rebuild. I could do the swap for what that will cost me, and have more reliability.
Depends on what your objective is for the build. I love the tuning and power the LQ9 puts out but the reliability and simplicity of the diesel is great too
Pretty much the same as yours.... family toy or if I need to/want to drive it to work on the interstate 30 miles away.
Appreciate the reply, and the videos!
Do you have a link to the AC compressor relocate for the LS?
Go check out Kwik performance
I'm building an ls for my K5 right now, do you think a low profile pan would clear?
I think they do but a call to off road design would answer for sure
I have a 91 suburban and I was wondering what's a way to make it sound loud?
don't do it. It will drive you crazy. Trust me on that one.
What about fuel delivery?
I got lq4 6.0 n 5.3 L33
let's say you have a electric throttle body how will you get the accelerator pedal to send a signal to tell it to open and close
You need the DBW (drive by wire) pedal and controller and cable. Donor vehicle should provide
Any idea where i can get swap parts to swap 1997 5.7 engine 4l60e i believe, for a 75 blazer.
It's the same. You have to get driveshafts from Truck with 700-R4
I have a 88 suburb 4x4 , LQ4 swap trying get rid of the TH400 , you have anyone that does 4L80 swap in southern Cali?
you mean, just replace a transmission?
Can you run the stock 700r4 with an LS? I have an 87 k5
yes .. 700r4 is a mech verson of the 4l60e... Call Summit.. You need a Shim (that what they call it) and a new flywheel. Some people use the flywheel from the old engine but I do not recommend .. it cheap and better to buy new.. bell housing is fine. You will not use all the bolts in the bell housing. I believe it the top bolt .. But all other botl up.. Also need kickdown cable and wield it to throttle cable if you running drive by manual cable.. Would not run drive by e wire due to more complications. YOu can run a manual oldschool speedo for the 700r4 speed sensor. Finally cross member will be same place . Maybe drill new holes but you should not. If it 4x4 the 241c or 208c tranfercase should bolt right up.. Once again.. Summit is the best for getting parts and ANSWERS if you get lost.. I have a 1990 k5 with 5.3 ls swap/4l60e to 241c transfercase 4x4.. Good luck.. B1.
Hey I got a 89 k5 blazer did a ks swap but my 4x4 slipps i gotta hold it to climp a hill can you help
sounds like you need lockers
Merrick what did you use as a rear drive shaft?
High angle driveline out of paradise Cali.
@@MerricksGarage what about the sye?
www.jbconversions.com
Who is going to work on these trucks in 10 years after they have switched hands and they need to be diagnosed and repaired
What transmission did you use ?
in the burb, I used a Tremec TR4050 and in the blazer I used a 4L65e
i see so many comments about motors and even in this video i was wondering where do you all store you batteries for you motor and for you motor are you running 120, 240 or 3 phase
Lol. I always try and call it an engine.
What did u do to get ur swaps pass California smog?
The burb was diesel titled already when I got it. The K30 is pre smog 73
@@MerricksGarage Haha smart guy..keep wrenching my friend
I've got a 16' Chevy 2500 with 170,000 miles on the 6.0. All maintenance has been done religiously. However, it appears (according to my local mechanic) that the "squeak" that has developed, is a lifter that has gone bad. My guy says the lifter has a wheel on the bottom of it that gets pitted and rubs on the cam wrong. He says this is a common problem with the LS and that I'd be better off putting a whole new engine in it than fixing it because there's a little bit of metal in the filter. Have you or anyone else heard of this problem?
Yea. Not good news
Some of the new LS motors have developed lifter/roller rocker issues. In this case it sounds like the roller bearing/s is skipping(rollers not getting proper oiling and not spinning but bouncing on the cam lobe). Mostly I’ve herd on gen 4 and up LS motors 4.8, 5.3, 6.0 etc.
Once there’s metal in the oil pan the motor (any motor) needs to be autopsied and look for any good hard parts.. then a full rebuild or purchase a full rebuild/junkyard motor.
Also the plastic lifter trays can cause the lifters to rotate when they are bad.. $5 part.. ruins motor!
That electric bottle I don't like that. What if your throttle gets stuck wide open with that thing
Electric throttles are DBW are pretty much in every car now
How do you get the speedo to work?
Vss on the tail housing of the transfer case
1980 chevy 3/4 ton 4x4 rebuilt 350 with a Rodchester QJet pulls like a hog all the live long day and gets 20 mpg. My question is why add all the electronics crap to achieve the same. Deep check book im guessing
I call BS on that but keep on keepin on brother!
@@MerricksGarage ya 20 mpg my white ass says not on yer best day downhill with a tailwind being drafted by a F-17 fighter jet uhhhhh ya
Burb?
Pacific Fab pretty much sucks, they don’t listen and put wrong plugs on then the customer service sucks when it comes time to get it corrected.
Yea mine were wrong too. Was it your injectors? Or alternator? Those are the only real ones with multiple options
Merricks Garage o2 sensors and maf sensor.
@@MerricksGarage no one every get the 02 sensors right. Even when you send them your old harness
What bumper do you have on your K5?
And will it fit on A k20 suburban 86
Front or rear?
The front one
The front is a DIY4X center winch cradle called an A-Bomb with the tubes added by me. I think they are making them with wrap bars and stinger now too. Check them out. Www.diy4x.com
Would having a body lift give it more room?
Yes a body lift will give more room but it comes at a cost. I would avoid them on these trucks.
Merricks Garage it already on the truck but I got clear 37s lol
Cut your fenders
Merricks Garage no I couldn’t do that. I bet I could make it work
If I take an AWD cadillac escalade with a 6.0 vortex, and put it in my 4x4 scout II will it work...or would it be best to look for a ls engine with a 4x4 drive train in place?
engine has nothing to do with 4x4 or 4x2. Thats what the transfer case is for.
Should I swap my 78 k10?
Yes

what i get a kick out of is people calling a bbc a l.s. engine just look up a 70 chevelle ss l.s. 6 and everyone has a bbc in it they think a ho 454 is a l.s. 6 454 i even had one guy say he has a l.s. 7 454 i had a good laugh at that one . i like the bbc but it is no l.s. engine .
they did make an LS6 and LS5? 454 back in the 70s chevelle SS's. it's not the same LS but it has the same name. the guy you laughed at was probably pretty confused as he was likely telling the truth to you
