I've been ls swapping my squarebody for almost a year now 😂 y'all are really doing a number on my self confidence

[@UNITEDBYTRUCKS]

Man, definitely don't want you to feel that way. We were crunching hard to make this happen for a show in Nashville this weekend. A good plan, parts ordered, and plenty of money do the trick.

[@ducaty100]

Awesome, I have a 1982 c10 can you tell what year LS 3 I should get and transmission and do I need a new gas tank thanks I have no experience what so ever on swapping engine but I hope am able to do it.

[@UNITEDBYTRUCKS]

You pick the motor and trans and go from there. Just make sure that your harness, motor mounts, and throttle body all match your application. the fuel tank could be a stock '87 tank with the efi provisions and then drop in a Walbro 255 tank. We chose to go with a new tank and AN flexible hose, which I recommend the new lines and fittings. They'll make the install much easier.

[@JohnSmith-qj4cf]

On the 4x2 wood blocks how high

[@YoImKneesh]

Where did you get the wire harness for Peco? I'm getting ready to do a 5.3l swap and currently doing homework on getting the harness to work on my C10. Awesome vids!

[@UNITEDBYTRUCKS]

Sweet! Thanks. The harnesses we use are PSI and can be found here www.psiconversion.com.

[@bigbawsz2054]

What’s the cost of an LS swap in a 69 Chevy c10? I just put in a brand new 350 and kind of having regrets. I really want to take advantage of newer tech like remote start

[@garyoja8608]

Were you able to use the factory vortec/ls belt drive and accessories set up ? I have been considering this swap in my 77 c10 TIA

[@UNITEDBYTRUCKS]

Yes, when using the Tejas trans mount and motor mounts, you can maintain that factory set-up.

[@Gsmith308]

Do you know what size that circuit breaker was?

[@beaudarvel7778]

What size breaker was used

[@luispagoada3098]

Hey when wiring an ls swap do you got to rewire the entire truck or how does the ecu connect

[@UNITEDBYTRUCKS]

No, just connect the 3 or 4 wires with your ls harness to your factory truck harness

[@diversedad7954]

So so you still need the factory engine harness from the engine or does the psi harness replace all of that?

[@UNITEDBYTRUCKS]

Nope. PSI has all brand new engine and trans harness together. You just have to use factory body harness and tie into new PSI harness

[@jameymote4598]

👍 😎 👊

[@jsee2385]

How about what pins is the ecu using on the air conditioning that keeps the truck idled up when the a/c kicks on. I'm gonna have that problem soon I'm sure. Lol

[@UNITEDBYTRUCKS]

I'll have to inquire with Alex on that but you can likely look at the schematic on www.psiconversions.com

[@jsee2385]

I looked at their harnesses after I watched. I'm cutting up the old one to save cash. If they have the prints I'll check them out, see if I can't tell what pin exactly it is. They usually just say like, pin 24-a/c single(something vague). Not like, pin 24-this wire will idle up the motor when a/c is requested. Lol

[@delrayjyd9676]

Thanks Robbie for having Alex in this video. I have emailed him about some PCM tuning for my projects. Here is a link to my 67 C10 LQ9 and 62 Grand Prix LQ4 swaps. kzbin.info/www/bejne/jqiskKKJoZeWjMk

Very cool! He's a good guy.

[@FloJohn-ni7ey]

Very nice thx for the video, what’s the part number or a link for the in tank fuel pump pls? Thanks

[@UNITEDBYTRUCKS]

That one should just be any WIX 255LPH in-tank pump.

[@19ADAM80]

👍🏼

[@jsynob]

Did you have to put new headers on for this swap or could you have used the stock exhaust manifold?

[@UNITEDBYTRUCKS]

You cannot use stock manifolds without cutting but you can use the TBSS manifolds or just save time/money and run the speed engineering headers.

[@nikkoduran2953]

I’m about to start my build, one thing I’m stressing about is if I need the same gas pedal and tac box from donor vehicle, for my drive by wire system.

[@RustyWrenches]

What did you think about that PSI harness? I used one on my build and wasn't too excited about it. I ended up re-crimping a lot of the terminals. I had several wires come loose when I was installing it. Curious how your harness was. I have to think mine was a fluke, but it did leave a bad taste in my mouth.

[@UNITEDBYTRUCKS]

Hey, RW! Man, I hate you had that experience with PSI. I've used them on 3 trucks now and never had an issue, other than having to extend the MAF wire with an extension. Alex has used them a ton as well. I would've sen that thing back, but I know how it is when you're crunching. Your truck has really come a long way. I love it!

[@RustyWrenches]

I'm glad mine was an isolated case. That makes me feel much better. I was pot committed by the time I found the problems, so I ran with it. Great content you've been putting out. I need to step up my game!!

Question: I hope you read my comment... I have running 1987 Silverado and a running 2003 Silverado 5.3 that I can buy for 900 bucks or use a 5.3 that comes with a transmission that I can buy for around 800. Is there a benefit to buying the running truck for my swap? More work involved if I have to pull the 5.3 from the running truck... Would I be able to use the cooling system from the 2003 truck?

[@UNITEDBYTRUCKS]

The fact that you know it runs and have every single little sensor etc available to you is reason enough to buy the donor. We used a donor here and we will use a donor on two upcoming trucks getting LS motors.
