Welcome aboard thirdgen.org.

Is the S10 4WD? If so, I doubt you'll be able to use the transmission. You certainly won't be able to use the Camaro transmission.

Do you have the whole S10? Hope so.

I don't believe I've heard of a member doing this specific swap. I would guess that you're looking at fabricating engine mounts and exhaust, and doing the usual grafting of the S10 harness into the Camaro.

^^^He said it was an extreme so it wont be a 4X4 I don't think. The motor mounts are the same as a small block Chevy on the 4.3 so you will have to get 3rd gen V8 mount pads(I could be wrong) but I don't have a clue on the wiring or computer.

What's different about the motor mounts? They are both V6 motors, have the mounts changed over the years?

As far as what you'll need goes, a 2wd trans from a vortec v6, the crossmember, trans mount, wiring harness and computer.


I imagine the computer is a standalone engine management system so you'll just need to follow the main harness back to the computer (which on my 97 vortec k1500 is under the hood). You want to take every wire that runs to the computer. You will also have to change the steering columns because some of the wiring for the computer runs to that or rewire it yourself to an on/off switch. On the 80's fuel injected full size trucks, its pretty simple. I have never done it on a newer vehicle though.

^^ The 2.8 is a 60 degree V6 and the 4.3 is a 90 degree V6 so the mounts are different I think.

The 2.8 and 4.3 are completely different. The only things they have in common are the arrangement and number of cylinders.

The earlier 4.3 mounts are the same a V8, but aren't in the same place. Fabrication required - the typical approach is to test-fit the engine and transmission, get the transmission located by hooking it to the crossmember, setting the engine down on the K-member, and marking where the mounts need to go. However, I'm not familiar with the 2000-up 4.3's. I'd guess fabrication required.

You won't need to change the steering column if you program out VATS.

there was a company making 350 to 4.3 mounts for anyone looking to down grade from a v8 to a v6 for better handling. i believe i saw it in sport truck or another mini truck magazine. but as said above, you'll need motor, tranny, and computer. you'll most likely need a custom driveshaft and you'll have to relocate the tranny crossmember. i thought of doing the same swap but realised it would be too much work. if you do it successfully, me and probably a few others would love to see a well documented thread on this.

2000 4L60E will be the same mount as LS1 4L60E, so use an LS1 4L60E swap crossmember from someone like Hawks. That will locate the engine/transmission front-to-rear.

I don't believe the 4.3 ever went to the LSx config, but I could be wrong.

4.3 is still 4.3, still in 2010 Silverado 1500s, never went to LSx config., dammit.
www.advanceadapters.com makes some bits for putting a 4.3 into a 2.8 S-10, just use those bits. It'll save you lots and lots of hassles and grief.

Hey, just sharing some information I've already gathered. The SBC and the 4.3L 90-degree V6 are almost completely indentical, minus two cylinders and 4.4" of length of the block. I'm still trying to track down mounts that will set the engine back far enough to let the transmission mount in the "stock" position. Both the SBC and the 4.3L V6 have the same bellhousing mounting areas. The bellhousings will swap. So...since the 4L60 and 700R4 are nearly identical, dimensions wise, it should bolt right up. Atilla the Fun and I are going back and forth on this on the "Definitive 4.3 Swap" thread. Apparently, he's done it already...once upon a time.
Oh, here's some Hot Rod articles I've find quite interesting...and INSPIRING. ; )

Bringing this back hey guys I have a 92 25th anniversary RS 3.1 v6 auto that I'm trying to put a 4.3 in. I am a auto mechanic and have access to all the tools, lifts and 3 senior techs with about 65 years of experience between the 3. Some of these parts I will try to make myself or get help locally to keep cost down but for now I need as much input as possible to finally get a documented 4.3 swaped into a third gen.

I was thinking of going with a 94 CPI block (no balance shaft) I would like to run vortec heads tho. Custom grind Delta cam not sure on the intake. I would like to use the intake from the hotels article above but would I be able to use them with the vortecs? Trans? Trans mount? The motor mounts are one of the parts I wanted to make myself to cut cost. Whatever engine I decide on will come with the computer, do I need it or can I use the 3.1's? And what about the harness? Anything else?? Fell free to chime in guys

Realistically the best way to do the swap would be to use the entire pullout from a newer S10/Blazer.

You could use the 3.1's ecm with some tuning and wiring work, but you'll need a normal port injection manifold for the 4.3.

If you started with a complete setup from something like a 97 S10 for example you'll need:

Swap the transmission tail housing section with the f body housing for the tq arm mount.

V8 engine mounts, you just drill the holes in the correct location on the K member.

Custom Y pipe/exhaust.

Extensive work will be needed to combine both harnesses into one harness using the 4.3's pcm connections and the thirdgens chassis/power connections.

Fail. I tried this, no go. Starting with a 2.8 or 3.1 car, the easiest mounting is Advance Adapters' part number 713119. And search farther back on 4.3, I already did a full installation with documentation, I just did it to show how, so I never bothered to get it running since I had running V8s sitting around.

i recommend leaving that car stock though, not a whole lot of those around

Have you looked at the production numbers on 92 V6 camaros ?

kmcn47

woops all i saw was 25th anniversary heritage and thought it was one of the rare ones

I would love to see the progress you have made.
