It would probably help to explain what the fuck an lv3 is. :homer:

 

The Gen V LT1/LV3 engine mounts are different but you can buy adapter plates. But they are LS to LT. So you would need to make SBC to LT adapter plates. Easy to do its just flat piece of metal.

The bell house is different namely the top bolt hole is off set which shouldn't matter as you just leave it deleted but the LV3 lacks a bolt hole at the upper pass side so you only have 5 bolt holes in it. But you would still need a crank bushing for the transmission I believe. But you can get 4l60e or manual bellhouse from GMPP.

Note the bell face difference.

Also the new motors lack powersteering pumps. You can get mount brackets for them though. Well at least for the LT's you can.

Also it will have a vacuum pump on it to help with brake booster as it certain ranges it lacks engine vacuum.

There are places that can rework harness and tune the ECM as well. Speartech is one.

 

So now that I know what it is I did some poking around. That's a pretty sweet engine, it would make a good candidate for swapping once the minor mounting issues are figured out.

 

Good info thanks. 208 motorsports says there are guys running lv3's with a th 400, and thinks one with a manual would be cool lol. He is almost certain they take the same pilot bushing as Ls engines. As for wiring they said harness and ecm they could do no problem at least

 

Pilot should be the same at least the LT1 is I believe. Only shitty thing is there is no way to delete the AFM. As a V8 cam will not work. There are aftermarket V8 cams out there.

 

Enough chit chat we wanta see a build thread! :bounce:

 

Ha me too. Do I have to be the first!?!:laughing::flipoff2:

 

Well I'll start half ass looking around for donor parts, and not buy everything at once, too easy that way to see I'm spending more on a truck than its worth:homer:

That's a great link, thanks

 

Randy built a 4800 bomber car, using one last year. I don't think he did a build thread, but if you have fb or ig, you may find some pics and a little info. I've been leaning more towards the slightly smaller Camaro variant (LFX) as the hp is a little higher and it was available as a manual from the factory, in case I decide to play by smog rules.

 

Yes, Slawson's 4848 car is a V6, 6L80e setup. He's been posting video clips of him playing in it. It's a sweet combo.

 

I used Hollander.com to buy an Aisin AR5 4x4 form a Colorado the other week (looks like new). No demand for them and prices are low, kinda like the LV3.

No support currently for the LV3 however for it from what I can see either. Until something big happens in the aftermarket, I see it as a dead horse that can't run. Even the 5.3 and 6.2 DI's are not supported until supply dries out enough to warrant the aftermarket to come to the rescue. I'd think real hard about it and not make any snap decisions until you have facts in hand.

Oh...if the LFX interests you...have a look at the LY7(261hp/260lbs) found in G8's around 09 (called Alloytec down under). Down a bit on power but the same experience on port injection (EFILive programmable). Has a bell housing to mate to a 4l60e and an unknown 6 speed (Aisin AY6). Doesn't sound all the appealing now that I just typed out all that.

My only interest in the lfx would be to get over 300hp NA, which I keep seeing 323/278 from the camaro and none of the vehicles show below 300hp. 300 hp is my target, if I can get that out of v6 packaging, I'll do it.

Ya need to verify it can be made to work without too much difficulty. Its not like the it used to be here on pirate, where guys had been there done that already:flipoff2:. I only got more interested when 208 motorsports said wiring and programming, thus I assume running would be no problem. I was hopeful it could bolt up to my Toyota stuff in place of my trusty old 4.3. My current 4.3 is '94 vintage, so something 20 years newer is in order, right?

 

Edited my last post a little. Was confusing.

 

General Motors :: GM LT1/LT4 Products 2014+ :: Wiring Harnesses :: #HVL435846 2014+ EcoTec3 4.3L V6 LV3-C Truck Harness (Manual Transmission)

Looks like a generic product image not for the 4.3, but for the 5.3 or 6.2.

Well this is looking a bit more doable . 208 motorsports quoted a similar price, a bit higher but included ecm tuning:smokin:

 

I bought 15 years ago a Howell TBI harness to retrofit a 850 Quadrajet on a 305 L69 HO (with a RV cam). Went smooth as Howell had good quality for the time. Dead reliable, the only thing I added was an add on board to the 7747 by Dynamic EFI to self tune out a bit of my lumpy cam. Can't say enough about how good a system that was.

 

So you have a GM adatper now? If so it will bolt right up save for the upper bolt and pass side upper one. You might can weld a tang on the upper mount area on the bellhouse and pickup the upper bolt.

Use the Gen V LT1 car flywheel/pilot. An LS truck pressure/clutch should fit the LT flywheel. Might use the LS pressure plate then your clutch disc too.

The gm NV3500 are pretty cheap and common. Not sure what transfer case you need or want. The 3500 will handle that power no problem.

Also with the correct flow pump you can run E85

 

Agreed, it *should* work with what you have, there will just not a be a kit.

 

The recent 6.2 CTS (Corvette?) had the only manual trans flywheel (dual mass) that appears compatible to the LV3 crank pattern (8 bolt 168 tooth neutral balance). Could be a buzz kill to projects until a billet steel (single mass) is made up. It wouldn't be that hard to do. I've been down that road with the Vortec 4200 recently. Interesting to note a LV3 at the Detroit auto show a couple years back had exactly what you would need. The picture is courtesy of Jeremy at Limeswap.com.

Edit....GEN V LS9/LSA might be the right flywheel.....researching.

Could this be it?

This looks even better.

Shit, yeah the LT1 vette now has dual mass. I think the new '17 LT1 camaro is same. It could still be used but have to measure the depth of clutch to See if the throwout bearing will work spacing wise. Also the splines would be different most likly on the clutch disc. But the trwin disc would suck for low speed off road use.


The LS9 is a Gen IV motor. If will not work as its a 9 hole crank flange. The CTS is a Cadillac it used the LSA starting in 2008 and now the LT4.

The LSA, LSX376, LSX454 and LSX454R engines actually uses a 8 bolt same as the LT1 Gen V and LV3.

The Ram is little cheaper at Jeggs it should work.

Then use a LS truck pressure plate and clutch disc for the trans.

 

Well now we're getting some good dialogue going. I may call advance adaptors and see if anyone there has a clue. I do want to make this happen, and I don t need to be in a rush fortunately. Went snow wheelin yesterday, couple feet of with a crusty layer on top. My 4.3 was working hard, and I think its getting a little tired finally

I find my 98 4300 vortec has the power for snow wheeling, but needs a better transmission with closer ratios. It bogs down on shift changes due to the wide gear ratio separation. I'm thinking of a LV3 with the 6l80e vrs the 4.3l vortec/4l60e I have now.

I currently have a 2014 LV3/ 6l80e on a pallet with 90 total miles on it, but it's going in another project vehicle!

 

We're going down to Koh this year, I'll see if I can't bug some people for more info on this swap when I'm down there:smokin:

 

4.3L LV3 Swap

I'm in the process of swapping a 4.3L LV3 into a 94 Toyota Pickup 4WD right now. It previously had the 2.4L 4-cyl that came with them and we're just going straight to this new engine. From what I've found, most parts are similar although they may require some modification. We've been messing with it for a couple months now, taking it slow, but hopefully it won't be too much longer before it's running. We're about to be at the point we can leave the engine in and start messing with all of the little things.

Great to hear about someone actually doing this. My tbi 4.3 has been a good motor, but this is the 21st century now. Are you using the 6l80e? I was actually considering keeping my toy 5speed, but not sure if that's an option as of yet. I talked to the guy at the advance adapters booth at Koh for a few minutes, and he said they don't offer anything for clutches for the 8 bolt crank, and he acted indifferent/not helpful about the whole conversation. Maybe he was there just to sell Atlas tcases...:shaking:. How can I find you on FB to like/follow if you post mostly on there?

 

I have jumped into this swap with both feet.
I'll give some early feedback.

208 motorsports does a harness and computer.
But be prepared to wait and wait to get it, or any communication.

Howell EFI makes a harness and flashes the computer.

Comp cams is making me the first camshaft for this motor and I'll swap out am lifters for Ls7 lifters.

I'm having the heads ported also.

Shooting for 400hp

The lt1 car accessories fit and pull the crank pully in 2".

 

That sounds awesome

 

I don't go on pirate much. I been posting on FB and instagram

 

Please post on here some more about your swap.

Facebook and instagram are cool for showing stuff as it happens but unfortunately almost impossible to search down the road for others looking for info on things like this.

This will probably become a fairly popular swap for toyota guys and it'd be really cool if you could help people find the needed information.

 

I agree it's just a pain to post pics on pirate.

I'm also going Tapshift on the 6l80e with a WINTERS shifter modified by .https://youtu.be/ceMycMnXoZc So it will run full auto in 4th or downshift to 3rd and it Tapshifts left to right

 

What are you using as a gear indicator? Speartech and PCS makes a display for gear postions. Or any OBDII dash will do it too.


The good thing with the LV3 is you can run the new 8L90 as well. Its not any bigger than the 6Lxx but WAY better ratio spread.

 

I forget where I read the v6 6l80 has fewer clutch packs and is lighter from this.

I looked up the pcs indicators. Very cool with paddle shifter!!.

I'd like to see the dry no converter weight of the 8 speed?

 

The full size truck 4.3L is same unit as the V8. The one used with the Colorado and the 3.6L is different.

The 8L90 weight is 218lbs with a truck converter the vette one is lighter. But roughly the same weight as the 6L80.

Can anyone verify fuel injector sizes? 4.3? 5.3? 6.2?
208 recomended up sizing to 5.3 injectors but all I keep finding are same size for 4.3 and 5.3

Are they sure they know your talking Direct injection not Gen III/IV stuff.

If your not going to run E85 I doubt you will run out of injector.

The LV3 and 5.3L L83 should be same inject ratings easy to get the p/n off the injector to see which one it is, should be 12656932 if its an early motor which is listed for LV3 and L83. I haven't seen a rating for them listed. I know the 6.2L L86 and LT1 is different 125.7 lbs/hr at 1,540 psi per LFP and no sure which p/n unit they are referencing. The L86/LT1 units should be good to 600+hp as well as the HPFP.
