OBS Chevy Truck LS Swap Overview

In this video I discuss and try to outline the process and the steps involved with successfully completing an LS Swap in these older Chevrolet OBS trucks although a lot of the information can cross over to the older Square Body trucks and even the C10 trucks.
It all starts with a Plan. Set a realistic goal and then proceed accordingly. If this video was helpful and informative, a Super Thanks is Always appreciated. 🫡
Get an engine that you’d like to use. Wether it is a 4.8L, a 5.3L, a 6.0L or even a 6.2L the process is all the same. Focus on getting the engine installed and running in the truck before you go crazy with the turbos and nitrous.
Prep the truck by removing the front end as well as your old worn out leaky 350 and make way for your newly acquired LS engine. Also carefully remove your old wiring harness.
Figure out which motor mounts you want to go with. I went with the Dirty Dingo Slider mounts but there are several other companies that make LS Swap motor mounts. If your truck was a V6 truck then you will need to update your engine cradle mounts to the V8 mounts because the spacing is different.
Prep the engine for install. This also includes doing anything that you would like to do or would be easier to do while the engine and transmission is out of the vehicle because it’s much easier to now rather than after it’s installed in the truck.
It’s now time to install the engine. The whole process is pretty simple and straightforward. I did the whole install by myself in around 30 minutes but if you have a friend around to help then the process may go even faster. But once the engine is installed it’s then time to move onward.
After the engine was installed, I them focus on the electrical portion of the LS swap which is a pretty big step.

@waldpetty4134 any notes on what the wires and color codes you used on your swap from your obs? I'm getting stuff together to do my 89 Silverado

[@MrTaterWedge]

One good thing about GM is they've been using the same bell housing bolt pattern since like the 60's

[@GMC-ck6sv]

17:01 I have a 92 tbi, so my fuel tank is not ideal and does not have that sump? If I purchase a 96+ tank, it'll have the sump and I'm good to go?

I'm not mechanically inclined but I can tell this was an awesome video however I would want a big block instead of a LS swap. I currently have a 1989 1500 that I want to upgrade from a six-cylinder to eight.

I made Sure to leave that part in there. I knew that someone would catch it and comment sooner or later!! That lets me know that you watched until the end so Thank you, and oddly enough this video is currently the most watched video in the past 48 hrs according to the analytics so maybe letting one rip is another way to trick the “algorithm”🤷‍♂️ 🤣

[@ipure2]

@@siTTinLo lol that works. I thought it was even more hilarious because you look a lot like my brother and that's exactly the sort of thing he'd do. I probably would too though so I can't go pointing fingers. Great job on the video. That was really cheap for a functional swap. Too many people leave everything but the engine itself non-functional and it becomes the next guy's problem.

I bought my truck almost that same way it had old parts put on a new crate motor by the time I got replacing all the sensors and all the stupid crapit came to life

[@jarianbrass5021]

What year truck did the 5.3 engine come out of?

[@valdemarlopez7133]

What did you do for a driveshaft? I’m not sure if you brought it up in the video but I’m having a hard time choosing what drive shaft to use or acquire

[@Desert_guy]

The engine bolts up to the existing transmission. Just record the ecm to the trans you’re using. Driveshaft shouldn’t change.

[@giovannimartinez2371]

Question did you delete the Evan system or you put it in?

[@raulcruz4182]

Im gonna do an ls Swap on a 96 gmc. 5.3 motor and transmission out of 00, did you have to replace the drive shaft ?

[@segulldodge1229]

The 5.3 will bolt up to the tranny you already have no need to swap trannys

[@raulcruz4182]

@@segulldodge1229 the trans went out

[@ernestorodriguez8228]

No just get dirty dingo swap mounts and use the 5.7 clamshells and you can adjust the motor forward or back to retain your drivshaft and trans placement the same
