You are a genius. Have a 2007 GMC Classic with the V6 and was just wondering if upgrading to a larger engine was possible. Notice you mainly work on GM trucks. Good to sharpen your knowledge and focus in on wonderful vehicles.

Thank you so much for the video .well explained ..

[@MohawkMotors]

You are welcome

[@drtb69]

Actual bolting it in is cake on these 2 motor mounts and tranny mount no sweat , i probably wouldve put the exhaust manifolds and a new cam and valve springs too before dropping it in...but i imagine your doing headers ? With the weight difference and likely deeper low rear gear you could probably run a btr stage 2 cam kit and she'd be super streetable with an easy 90+ hp gain so worth it. What about the computer ecm is that plug and play or is the wiring completely different for the v6 .. another reason I'd switch out cam and flash tune the ecm or at least budget for it

[@MohawkMotors]

yeah we did shorty headers. Didn't do cam or valve spring because he didn't have any room left in his budget at the time. ECM need to be programmed to recognize the new trucks VIN as it's own or have VATS deleted, wiring is mostly the same as far as connecting it to the truck.

[@dougaranda6187]

I have a 2007 Classic 4.3, 2wd, and I'd love to do a swap. Only problem is, there's so many different opinions on what has to be done. I always heard motor mounts, fuel line adapter, and ecm reprogram. You say lots of other things need to be swapped too. I guess the easiest thing to do would be just to do it and figure it out for yourself.

[@MohawkMotors]

You'll definitely need to change the motor mounts and reprogram the PCM, I don't think you'll need any fuel line adapters. You may need other parts also. It just depends on exactly what you are going to do and what level finished product you want. I suggest getting as much of the stuff that you'll definitely need as you can, then start, and get the stuff that comes up as you go.

[@mikebrown495]

I’m also doing a swap on an 07. Make sure your donor v8 is from a drive by wire truck. Even though the v6 is drive by cable the truck is wired for the v8 drive by wire stuff and it won’t work with the older cable v8s . I believe it’s 04-07.

[@thegman4759]

Great build! I have a question does it work to put a early 2000s 5.3 into a 2010?

[@MohawkMotors]

Can be done, but it's much less complicated and much less expensive to just get a 5.3 from a 2008 to 2011 model truck.

[@raymundolimon7545]

i have a 4.3L v6 2014 gmc sierra single cab, i wonder if it’s possible to put any sort of v8 swap into it. if so how long you think it may take and how much it’ll cost me? awesome video

[@MohawkMotors]

I'm sure you could swap a v8 from that generation truck into it. As far as cost or time to do it? I have no idea. Estimating off my limited knowledge of that platform, I would expect to pay at least $4,000 for a complete pull out engine assembly, probably another $8,000 to $10,000 to pay someone to actually do the swap. If they were experienced they could probably do it in a month or so.

[@claytonmccollum9692]

I have a few questions as I am looking to do this swap as well... Can you use just the plumbing for the cooling system instead of swapping the radiator? Same as the AC components, I know on a 5.3 swap all you need is the plumbing for the cooling and AC system. Do you have to use the donor fuse box or can you just plug the harness into the original one? Do you need a new ECM or can you just have the V6 ECM tuned?

[@MohawkMotors]

Yes you can re-use the V6 radiator and the V6 Condenser and evaporator. Most of the AC lines and the Coolant lines are different though, you will need the V8 lines and hoses. You can use the v6 fuse panel as well, you just need to be aware of the differences in the fuse panels between years 99 to 02, 03 to 05, 06 and 07 classic. Some V6 pcms are capable of running the v8, some are not, it depends on which operating system it has, some operating systems are not compatible with V8 programming.

[@Thediecastvault]

So I have a 2000 single cab Silverado it’s a 4.3 v6 as well and I want to do a swap to 6.0 , does it matter what year truck the 6.0 comes from? Or no

[@MohawkMotors]

You can make any gen 3 6.0 work, but the easiest way to do it, will be to find one from the same year truck, 2000. A 2001 or even a 2002 would work also and be relatively easy swap. In part 2 I touch on this and in part 3 coming next week I go much farther into depth.

[@nicolasp2200]

Hey man I have a question. I have a 02 4.8 Silverado and want to swap either the lq4 or lq9. Would either or be plug and play overall other than the ecu reprogramming.

[@MohawkMotors]

If you can get an LQ4 from 01 or 02 it'll be plug and play bolt right in. LQ9 only came as drive by wire, but would still be an easy swap, just put the intake manifold from your 4.8 on the LQ9 and get the correct oil pressure sensor. Otherwise everything bolts up the same.

[@gerardolopez5875]

What about the driveshaft? Custom made? Or the stock from shortbed truck?

[@MohawkMotors]

We have a couple options, the stock driveshaft necks down from 3.5 inches diameter for most of the length to 2.75 inches on the ends. The driveshaft out of the 2500HD donor truck is 3.5 inches the entire length. Once I have it all buttoned up and can measure for length, I'm really hoping that the longer 4l80e is long enough that we can shorten the original 4l60e driveshaft to the 3.5" diameter portion, and weld in the 4l80 yoke. That would be the simplest and least expensive option, and out would place the "fuse" at the axle yoke where a driveshaft loop and be easily added

[@aromee7696]

I got a 06 Chevy I lost compression in 2 cylinders but I got a 6.0 lq4 out a 2500 05 Silverado gonna Takle this soon any tips you got for me lol

[@MohawkMotors]

Is your 06 a V8? If it's a V8 it's pretty much a direct bolt in swap, you'll just need to get the computer tuned to run the 6.0. If it's a V6, then you'll need to do pretty much everything I outlined in this build series.

You can just have the 4.8 pcm segment swapped to run the 6.0 very easy to do with hp tuners

[@Am-kb4cb]

Hey what’s up man I have a 4.3 manual v6 looking to doing a 6.0 automatic 4180 transmission is it poss

[@MohawkMotors]

Yeah it's possible, you'll need to decide how you want to do the transmission shifter. A console style shifter would probably be the easier route but you could swap in an automatic column and have column shift also. Swapping the engine would be the same, you'll just have to decide how you wanna do your transmission stuff.

[@getducked6355]

2005 5.3 swap wanting put my 03 6.0 will it work or I have change lots parts

[@MohawkMotors]

Very simple, put the complete intake manifold, wire harness, and accessories from the 5.3 onto the 6.0, and get it tuned. Done deal.

[@JAMESYBOY.]

I wonder if it would be plug and play if you were swapping out a 5.3L to a 6.0L From my understanding damn near all the sensor are the same?? Any thoughts on that???

[@MohawkMotors]

As long as it's the same generation engine, it's plug and play. the ONLY differences you could encounter in the 99 to 06 truck engines could be oil pressure sensor (99 to 02 use single wire, 03 to 06 use 3 wire), throttle (either drive by wire or drive by cable), and injectors (flex fuel 5.3's use a different injector connector than the non flex fuel 5.3's and 6.0's)

How much would something like this cost ..if you have a 05 Silverado with a 4.3L V6 and you wanted to swap it with a 5.3L V8

[@MohawkMotors]

Are you meaning to do it yourself? If you're resourceful you could do it for free. I swapped one of my own trucks from a 4.3 V6 to a L33 5.3 V8 and actually profited. I bought a crashed donor truck that had everything I needed for the swap and sold what I didn't need. I sold the parts I didn't need for more than I paid for the entire donor truck, used some of the proceeds from selling what I didn't need to buy new parts (new motor mounts, motor mount brackets, a new transmission mount), and still have my engine, harness, and everything else I needed to convert my truck to V8.

[@mohamadatta719]

I plan on doing the same thing in my 2001 what all parts would I need I don’t really know that much

If you swap from a v6 to a v8, will it still pass smog?

Depends on where you are and how they check. If they actually check under the hood, it'll be difficult to pass since most people can tell the difference between a V6 and a V8 by looking at them, although some can't. If it's only a plug in check, then you can program the V8 computer to match the VIN of the truck and shouldn't have any issues as long as everything is functioning correctly. It just depends on how the inspection is done.

@@knkmphd understandable. Even though it's not a terribly complex job to do if you know what you're doing, it does take time to do a nice job so I'm not surprised shops want a premium price to do it. It also technically could be considered emissions tampering if you live somewhere that is picky about vehicle emissions. All that said, if you have the tools and equipment, you could do this swap in the street with a engine hoist and a pair of jack stands over the weekend. Could at least get it far enough along that it looks complete and keeps the HOA off your case if you have one.
