How to LS Swap a Squarebody PT.3 - Installing the Engine 

DUDE I LOVE UR BACKYARD !! it looks like my backyard straight Mexican...

I thinking of putting a LS in 86 chevy truck and the information you are giving is great keep up the great work.

I’m a big fan of the Tejas motor mounts for square bodies. Keeps the motor high so that deep oil pan is flush with the crossmember and you can keep the factory ac compressor location if you want. They do usually require a new driveshaft though, whether cut down from the donor vehicle or full custom.

I used the LSX Innovations swap plates and stock 5.7 clam shells. My th350 driveshaft slipped right in and fit perfectly. The ones i used are also adjustable so you can fine tune the fitment

Just so you know those adaptor plates are backwards but don't listen to the haters, you can do it that way and sometimes it's even stronger. I've done a lot of those swaps and yours is pretty easy even with the A/C. The earlier swaps, '72 and back, need to be raised an inch because of contact with the drag link and the pan hangs under the frame crossover. Nice work, use your choice of electric pump with the Corvette regulator/filter and run a dead head fuel system and you're in. There's also extended driveshaft yokes available for the transmission so you won't have to spring for a new driveshaft. Speedway or Ebay can help you out.

Nice work. I am currently working on the 96-2000 black box to 0411 computer swaps because I have several vortec engines. I'll be using HP tuners for the tuning. After those projects are done, I'll be getting on with the LS swaps, so I'm definately looking forward to your videos..

They make longer than stock yokes for the 4l60 so you don't have to buy a whole drive shaft. Just get the extended yoke.

Your adapter plates are on backwards. If you flip them, you'll move the engine back 11/2 inches, and not have to change driveshafts. You'll still have to notch for the ac, but everything will work

Thanks for the info

WOAH! Getting me motivated to put a hemi in my d150 😂 sadly I still have a long ways to get to that point. Good video!

For you a/c notch out then box in frame mines a c20 1974 lq9 t400 gear vender and I shorten frame to take short bed it is crew cab

Haha that’s funny you made the same mistake I did. I ordered those engine mounts too just to realize the factory ones work better

Hope you don't me saying 454 andc350 in a c20 the mount tha go from the frame to the crossmember are different and I notch my crossmember for ac

Where did you get the aftermarket mount from? And what holes did you end up mounting to? Thanks, for keeping it real...

I don't know if I missed it I'm trying to figure out what oil pan I can run for my square body swap and what brand motor mount plates you used? Great information in the videos Man highly appreciated

Wondering if you were to put ac on if it would affect the mount of refrigerant in the system. I'm sure a square body and modern truck have slightly different capacities.

Where’s part 4?

i plan on taking out a 5.7 vortec and replacing it with a 5.3ls in my 1999 gmc c1500 what all will i need besides motor mounts?

Did u have any issues with the stock ls engine oil pan hanging too low from the bottom? Im starting my 5.3 ls swap on my 1966 c10 soon.. Thanks for your videos.

Hopefully last question. How did you wire the alternator? Which wire from the truck did you wire to the alternator?

How did you adapt the LS power steering pump to the steering box ?

What's your take on the dirty dingo motor mounts for the square body? That's what I was going to go with but they also say you need to notch the frame for low mount ac. I'm hoping I will have enough movement with the mounts to use at least the stock transfer case cross mount.

Did you find that having the exhaust manifolds off made it easier to drop in and bolt to the mounts?

Actually looks more pain in the rear you guys get different motor mounts you got to get a different wiring harness you got to move your transmission mount up you got to get a different drive shaft that seems a lot of work

Where’s part 2

Do c10 and k10 use different LS motor mounts?

Question if put 5.3L on c10 1984 need replace the oil pan or fit with the same oil pan

U thick that 4l60 would strong?... Doing a ls swap on my 87 crew cab dually...and yes..u can used the OG exhaust from the 5.3..keep up with ur videos..one more think, I got a 4.10 meybe urs is the same...4l80 is the ticket

Or you just buy the $99 flexplate and adapter to keep the better th400. Then you want have to add to the driveshaft.

Where are your chains connected?

That starter might be a bitch to change out later!

Clean the block up tho at least💁‍♂️🙋‍♂️
