There's enough room, but you may have to make room in front of your engine by recessing your radiator into the core, putting the fans in front of the core, or some combination thereof.

COST DEPENDS ON HOW MUCH U DO AND WHAT PARTS YOU USE. I HAVE ABOUT $2500 IN MINE BUT I USED EXPENSIVE PARTS (U GET WHAT U PAY FOR)

I have a 1996 2.2l and am in the process of putting in a carb zz4 with a t56 tranny. My question comes to the wiring. Can i use any of my stock wiring or do i go for a whole painless kit?

You can keep your stock wiring. For the engine all you'll need now is starter wiring assuming a custom gauge setup.

Don't forget to ground your engine.

ok heres tha deal........95 2 door 2wd blazer......... carb. 350 small block, th350 tranny ok now all this will bolt in with mounts and tha tranny will bolt in on tha crossmember as if it was tha 4l60 right???? now tha other question is will i need a new driveshaft? shorter or longer? im goin all old school no computer what so ever so i just yank out everything electronic im pullin out my air conditioning heater w/e i dont use is coming out my wheel wells are coming out everything brake box (not master cyl) and i know i can use tha pulleys off of my 4.3 on tha 350 so tha question is tha 350 will bolt in with no drilling or fabbing? tha tranny will bolt in with no drilling or fabbing? and do i need a new driveshaft?

[bluedragonx]

The answer to all of your questions is a big resounding MAYBE.

Some fabbing is likely to be needed one way or another. May have to bash the firewall, may have to recess the radiator, may need a custom tranny crossmember, may need to shorten the driveshaft. Depends on decisions you make during the swap. For example, if you don't want to shorten your driveshaft you may need to recess the radiator. Things like that.

will my tranni out of my 2.2 98 sonoma fit up to a SBC...with or with out a bell housing adapter?!? it is 5spd

[bluedragonx]

No. It would break, anyway. Get a decent tranny.

Treat it mainly as a 2.2, nearly everything will need to be replaced.

The rear can be salvaged depending ratio and power level of the V8 dropped in. Driveshaft maybe used some cases too.

how would i run a carb instead of a fuel injection? my dad and brother both say it will run better with a carb.

Then your dad and brother need to put down their wrenches and pick up a few books on FI. Fuel injection will give you more power and will be more efficient (better mpg). This is assuming you choose a worthwhile FI setup, MPFI specifically. TBI will not produce power like MPFI.

Really, though, the power you'll get will come down to tuning. If you can tune a carb well and choose the right carb for the application you'll be good to go, but you'll still have to retune the carb on a regular basis to keep things running in tip top shape. FI will adjust everything according to various conditions in order to keep it running smoothly. Again, in order to get the most out of FI you'll need to tune it as well, which means reading data from the ECU and reprogramming the computer based on what you learn. More involved, but you'll get more out of it.

When choosing between FI and carbed you need to consider your needs. This applies for the whole swap. This also assumes you're willing to do everything necessary to meet your needs.

How about a 2.2 conversion to a 4.3 .

It's not worth it. You might as well swap in a V8, you'll have to do pretty much all the same stuff. New motor mounts, new wiring, fabbing fuel lines, different exhaust, new radiator. All the same stuff you have to do to swap in a V8, and a 350 it's gonna cost much more than a 4.3, if any.

To top it off, if you choose the right V8 your gas mileage will be just as good, if not better, than the 4.3.

Alright...I was asking some questions here at work about the vortec 350 I bought, and I didnt really get anywhere. I was reading in the previous posts that the vortec 350 needs some kind of computer shit? I dont want to have to deal with fuel injection or anything. What do I need to do to get this motor to run on a NON-fuel Injection system? Anyone?

You just need an intake manifold that will fit the Vortec heads. Other than that it's the same as any other carbed smallblock.

[GakiAkuma]

Well what about the show on trucks, wellis it as easy as they say?

Motor, MMounts, headers, ecu chip and a V8 TBI from holly?

What year S-10s will one be abel to use the stock trans? Heard about that one somewhere.

Also what about the rear end so its not a one wheeler? would prefer the stock housing so I wouldent have to change out my setup.

[94low350noma]

If that tape from Trucks is still goin' around I would like to know where I could get a copy... anyone?

Camaro exhaust manifolds will work. Or, "Over-the- Spark Plug" manifolds.

i left the stock manifolds on my 305 its an 85 with camal back rear dump and all i did was replace the stearing colum with one out of a van that had a slimmer one, fliped it upside down and cut the old end off and drilled a hole in it for the upper part to hook it up worked great and have plenny of clearance. i veven belive that it would have worked with the old headers that werent camal back and i got the headers from a bone yard for free, minus that i had to take it out myself

also fi cost more upfront to put on if you dont already have it on there. i personally like carbs b/c there cheap and readily acsecable (SP?) if you have fi on it keep it but if not i would recomend keeping the carb unless you have money to put iit in it also is all on what you want to do with your dime im wanting to do the old skool blower thru the hood ect. adn i grew up working on the carbs so i know more about them but its all personal and with the being more effiecent that depends cause i can tune an old carb in and get 30+ mpg as long as i keep my gass pedal off the floor and still can beat a 95 camaro in a 1/4 mile race easilly and in a 1/2 mile be a half car ahead. again it just depends on what you know and feel comfortable working with.

accessable... i believe. Hell, I could be just as wrong. After all, I'm a H.S. drop out with an A+ cert.

thanks korny i suck at spelling just never been a strong point of mine i figure i dont need to spell to work on a truck or cook but hey i think your right with the spelling it looks better than mine

[01cherryreds10]

No one has a parts list for a 4.3L -> 305 SB do they?

I looked in a magazine and they showed I needed a modified oil pain, motor mounts, and headers.

But if I'm doing a swap should I replace the wiring harness and computer to make everything run right?

I really don't want to do a half job, I want to complete it, but not busting my wallet.

Thanks if anyone has the parts list btw.

[Nazgulmagefreak]

I will be going from 4.3TBI to a 350 Vortec engine with TBI. (link to example build)
I should be able to use the engine harness off of my 4.3, right? Or do I need the harness from a 350TBI?

Also, I have replaced my computer before with an Autozone replacement. The computer says both 16196395 and 16197427. Does that mean that it was meant to replace either stock? So my stock ecu was either number? I am looking at this EBL board. That way I don't have to worry about the stock computer and I have plenty of room for expansion and datalogging is a big plus.

Is there any difference between the 4.3 Throttle body and the 350? I think I read on thirdgen.org that the 4.3 throttle body with the same unit on the 305TBI.

[curt_k16]

is there a diffrence between 2.5L motor mount bolts and 2.8L motor mount bolts?

[Dropt4]

I have a 95 dime with the 4.3 Vortec and I am swapping in a 305 soon. I know you can use the tranny, but I am doing a carb not EFI. So what all do I have to do to make the swap work? Can I still use the tranny and what all do I have to keep from my computer to make the swap work? I am new to the V-8 swap and have good knowledge on rebuilding engines, just now swaps. PLease throw me some help. Thanks

the actual bolts or the mounts?

[tjsanders]

how about the oil pan and steering if your truck is bodydropped.

[tjsanders]

im in the swap process right now, if your truck is bodydropped you will have to use manifolds or move your steering rod, i have a set of the conversion headers and they hit were my truck is bodydopped. If you use a mechanical fuel pump you will have to notch out your frame, the best way is to run an electric pump and block off the fuel pump hole. The trans will bolt right up, but if it is a 5 speed you will have to change the flywheel, the center hole is a different size.

[i2coofooyoo]

Darn well that post was helpful but I have a 1991 S10 that had the 4.3 fuel injected engine. I am putting a 350 in it that is carburated. Is there an aftermarket wiring harness I can use or do I just modify the one for the 4.3L? And as for the gas tank, can anyone tell me what all parts I am going to need. Thanks for any help.

[92s10ex]

hi. i have a 92 s10 2wheel drive. with 4.3EFI and im putting in a 350 that is not EFI its outta a 76 chevy silverado. im wondering what im i gonna to have to do to my truck and to the motor to get it to fit. the motor is about as basic as u can get no a/c or nething like that. what parts will i need? thanks..

[ericlaydsonoma]

i need some good pics of a 94 2.2-350 swap and also where is the best place to get the engine mounts

I do know you can program them to do different things such as whether or not you have the theft deterrent system. I'm just wondering how much of what the BCM does is influenced by the computer. They talk to each other via the serial data link. In other words, if I put in a different one, will the BCM flip out?

If you put in a new ECU or replace it in any way it needs to be programed to YOUR car BCM or it will not comunicate properly if at all!

[tjr5150]

I have a 90 350 with tbi. Can I put this in my 98 s10 with 4.3vortec?

[mandar06]

I swaped a 4x4 1993 4.3tbi with a 5.7 tbi. here is what i did.

(Lower End)
Bored .030 over
block was shaved on the inside for clearance
400 crank
largest possible cam with out bending stock valves and pushrods
high pressure oil pump spring
stock heads
(What you need to buy for a four wheel drive swap)
Milodon 4x4 pan
Lt1 corvette radiator
4x4 motor mounts
1999 to 2007 lowpro BB oil filter(does away with that leaky relocator)

i have less than 15 hundred dollars in mine and it runs like a raped ape, but all the wires going eveywere makes my motor not look as good as it should.

[jw850]

one question it may b dumb but i got a carbed 350 im wanting to put in my 96 blazer which has a 700r4 i know it will bolt up but will it work?? i mean isnt there electronics that run the tranny a lil or somethin i dont wanna bolt it up and burn the tranny up

if you live in a state that tests emissions no cause you must have same year or newer ecm, unless you could make that 350 work on a 1996 or newer ecm.if not get the harness and the ecm for that motor,make sure you tune it when your done.if it does'nt have an ecm then it should be easier.

[SuperFastBrad]

So is there a company that makes a swap kit designed for a 2.2 to a LS1 or 5.3 Vortec in the newer body style? (1999) Thanks for the help!

[cpt. howdy]

i have an 89 2.5 and i was thinking of doing a swap. do you think i could do it for under a grand and what about the gauges what would i have to do and would a rad out od a 4.3 vortech motor work for a 305 or a 283?

[minimudder]

I've read this post and others that are simliar, but still have questions. I have a 93 Blazer with the 4.3 Vortec. If I want to put a TBI 350 or 400 in, could I use the computer and harness off an 87 1/2 ton? The reading in the first page said that it should, but computer/wiring isn't my strong area.....

[syclonekid43]

i just looked at this whole thread. im building my 350 tb motor out of a 93 buick roadmaster. its goin in a 92 4.3 vortec 2wd . i cant seem to find if the harness from the roadmaster will bolt up to the junction plug on the fire wall and have everything inside my truck work like it did. like the gauges and what not.

[hodgie]

I swapped the 4.3w that was in my 99 4x4 ZR2 for a 2000 LS1 motor. It took alot of money, time, and some fabrication it took me almost a year but I did everything myself except for having Currentperformance flash the computer and make the engine harness. Stripped my truck down to the bare frame but it was all worth it. It is even emission legal in the state of MO passed on the first try.

[Big96Zr2]

got some pics of your truck/setup?

[s10nooby]

ok i didnt want to read all the posts so i dont know what alls been posted im going carbed with my82 gmc caus it is carbed and i HATE i repeat HATE dealing with fule injection every car that ive owned that had it always ran like shit and i had to go to a dealer or something to get the codes read and it was all $$$$$ out the ass so what is the deal to put my 305 chevy v8 into my s15 like tranny adapters and engine mounts stuff like that any one pelas and dont tell me to go to FI or i will flip thanks rob

[danoc81]

ok guys this is my first post here i have a few questions. first of all i have a 92 s-10 with the 2.8. i am swapping a 307 my dad reabuilt for a 65 chevelle. it is carb. and mech fuel pump. how can i bypass the electric in tank pump? second i am using a 350turbo trans will i need a new driveshaft? it has the 5spd in iit now? third i am going to be selling everything i remove if anyone needs a replacement. the motor has 150000 on it and still runs great the clutch is a brand new centerforce. the trans is toasted all of the hydraulics are brand new ty please help

[syclonekid43]

i think im gonna swap my harness out for a tbi motor. this way i play it safe and know my gauges and what not or gonna work.
dont think my set up is gonna work. i have a 93 roadmaster tbi with a 94 fu size harness and he raodmaster compuer. figure its easier to use a 4.3 harness

[blazeboy]

i have been kinda curious on this too,

[syclonekid43]
