WHICH LS ENGINE TO CHOOSE FOR YOUR SWAP!

In this video I do my best to give you a general idea of which route to go for your LS swaps engine.
There are many more technical factors as to each engine when you talk about internals but this video is not that specific. So, if you have any questions for that it's best to ask google.
Hope this video helps!

I knew this was getting serious when the glasses are on. Dude this is gold.

[@RustyZipper]

Tire Kickers and Time Wasters will ruin your business. I would charge them a $100 consultation fee for 60 minutes of your life. If they want less then it’s $2 a minute. You would be amazed how direct people will get when they know the clock is running like a Taxi meter! If they actually go through with the swap with you then that money is applied to their balance. If they aren’t willing to part with $100 (or less) to save themselves $1000’s in headaches then it’s a waste of your time.

[@krustyclassicsgarage]

lol I agree. I just try to be a nice guy and help people out but, its starting to get to the point where I'll have people contact me, specifically tell me they want me to do their swap. We talk for days and then nothing, which it doesnt really bother me. Would just be nice to be making some money.

[@jraposo911]

God will repay you 😊

[@AlazarAnbesaw]

I agree with the consultation fee! It's a sure way to weed out the tire kickers and the serious ones.

[@focused313]

As a potential customer, I agree. Some people can't get their cars worked on because the people doing the swaps spend 20 hours a week talking to people that aren't paying to get work done.

Gen 5 L8T with a ported injection conversion and a gen4 ecu will get you basically a 400 cubic inch LS/LT hybrid with no DOD to deal with. It is a 6.6 liter iron block and ready for boost. You can run holly terminator x with this setup.

The stock rods in these L8t engines will diasgree with your boost ready statement.

[@krustyclassicsgarage]

I have a video on how to hook up an LS swap harness.

[@GrandPitoVic]

I am working on my first swap. Ls3/4L80. 03' Crown Vic Police Interceptor. The only reason i am doing a Gen4 is a found a Ls3 block for $500 and I already have crank and Gen4 rods and pretty much everything else. I just need to pickup a set of square ports as soon as i get the money. My block is in the machine shop right now.

[@Hoosier81]

How much was the machine shop, what did they do? If you don’t mind me asking??

[@GrandPitoVic]

No problem, I don't mind at all. I paid $850 at the machine shop. But, I had 1 sleeve replaced. #5 cylinder. Then bored, honed, decked and cam bearings and main bearings line honed. The sleeving was $350. That included decking. They had to bore it .20 over because of sever taper in the cylinders. You can do .20 over in the Ls3 if they check the block ro make sure there is enough meat there after. Because of core shift. Some you can not. But you can never run boost. Which is fine with me. I'm not trying to be the next Street Outlaw. Lol. And I just bought a 6L90 transmission core for $300. So I will be running that instead of the 4L80.

[@Hoosier81]

@@GrandPitoVic ok thanks a lot, just trying to get a basic idea what the machine shop will charge.

[@GrandPitoVic]

It would have been $80 to hot tank the block. $80 cam for cam bearing, including the bearings and $80 or $120 to hone the cylinders. Depending on the blocks condition. It could be cheaper or more expensive. My block needed the sleeve and extra work, so it ran up. But it is still cheaper than $2500 for a new Ls3 block lol. I found this block for $500 cause it needed a sleeve. I haven't been able to find just a used Ls3 block for less than $1500. And it still needs all of the work.

Gen IV is the way to go!!!!! There are plenty of 4.8, 6.0 and 6.2 that dont have the DOD and no VVT. Just change the single bolt cam out for the 3 bolt cam and always of course install ls7 lifters. Plus the MAF sensors are better design on gen IVs.

I fully intend (now that I’ve learned from your videos) to run it exactly like you are in your car, any information would be great, I want to do my swap asap so I need to know exactly what I need to make it work on the electronic side of things, mounts and all that I can figure out myself, best and easiest fuel pump recommendations as well? Thank you in advance, I’m new to this, it will be my first LS swap ever

[@krustyclassicsgarage]

You'll need the harness adapter for a 4l80e if you go with the cheap harness. Or go to BP automotive and get a harness that's set up for a 6.0/4l80e. Then you'll need your factory ecu tuned for a swap meaning getting vats deleted and some other things or get 1 already done from eBay for $160

[@mikebonifas4925]

[@prnd21turbo]

Does a LS3 Tr6060 combo I got from a 11 Camaro have a tac module? I’m confused. Yes google has the info but it’s just overload. Can’t get a definite answer. The engine came with the mass air flow sensor, gas pedal, ecu and full wiring harness. Allegedly. After reading to much and overwhelming myself before I’ve even attempted anything, I have questions. Seems daunting ….

[@krustyclassicsgarage]

Yes, its dbw so it should have a tac module. Take a break, being new to this stuff and researching it takes you down different rabbit holes all at one time lol. Big reason why I didn't go in depth too much about each engine in this video. Wanted to keep it as simple as I could while trying to give as much info as I could.

[@GrandPitoVic]

But to see money I am thinking about putting a 24x crank and a 1x cam gear and run a Gen3 harness. I hear the Ls3 will still run strong with it.

[@krustyclassicsgarage]

Yes, just use the adapters they have for the gen 3 harnesses. I haven't used one so didn't want to try and talk like I have in the video.

[@johngilbanni5891]

I’ve got a 416 with a 24x crank and the stock 411 computer runs it fine. I did have to use a newer truck MAF and I think LS2 knock sensors. For anyone going from a bare block it’s what I’d recommend to keep it simple and not rely on a conversion box.

[@GrandPitoVic]

Yea Def not spending that kind of money on a Lingerfelter converter lol. With it tore down, it it would be way cheaper to have a shop swap my reluctor wheel on the crank. Thanks for the info. I Def want cruise control and traction control that I can turn on and off. I'm going to do the drive by wire so cruise is way simpler to get working. They sell aftermarket control switches to work with cruise. Traction control I'm still researching. Traction is controlled by the computer but a switch is what I need to find.

first time swapper here. I have a 99 rust free southern GMC suburban 1500 4x4 OBS 5.7 and 4l60 and a 99 frame rusted GMC extended 4x4 1500 5.3 with 99k miles. They are only made a few months apart. Will I have fun or poop my 63 year old pants with this project? I haven't started yet and have an option of just buying a crate 5.7 and restoring the drivetrain.

[@krustyclassicsgarage]

99 OBS is practically already set up for an LS. There is a difference in transfer case but being youre putting it back into a chevy theres plenty of threads out there on google of people that have done it. Id highly recommend going the LS route if you want to actually drive and enjoy the truck. Nothing wrong with a rebuilt 5.7 but theres a reason every one LS swaps.

This is a different way of trying to explain GM V8 engines but can be pretty confusing the LSs are aluminum performance blocks LS1,2,4,6,3,7,9. 1997-2017 then Vortec engines (mostly cast iron blocks LR4,L33,LM4,LM7,LQ4,LQ9 made at the same time but for mostly trucks SUVs now the LT engines are all Direct injection and the next line of High performance engines for GM LT1,LT4,LT5,LT2, and the LT6 which is DOHC and Flat plane crank so it will be completely different form GMs typical engines. Also along with the LT was 5.3 and 6.2 ecotec with active fuel management and Direct injection

[@krustyclassicsgarage]

Yup but this video isn't to get that technical. All that would do is confuse the target audience. Anyone who wants to know more about whichever engine they choose would just do more research on it after watching this and deciding which one they'd prefer to use.
