Swapping? Heres A List Of Parts And Answered Questions!

[recoil]

I have a 92 sonoma extended cab I'm about to swap a 350 into, so all I need is headers, mounts and an electric fan, correct? I currently have a jet stage 2 chip in it, will I need to remove that and go back to stock chip for this to work? also, is the computer harness plugs the same from the fullsize 350 the same for my truck (the actual plugs that plug into the computer box, if it is I'll get computer and all from the donor truck) one more thing, it is an ext. cab with the 2-piece drive shaft, I want to loose that and go with a one piece, is there any shafts out there that's the right length or will have to get one custom made? maybe one out of a longbed s10 or fullsize.

[umpalumpa7777]

i dont have time to read this whole forum to see if someone asked this already but i have a 91 with the 2.5 in it and i wanted to put a 350 in it and i was wondering what would need to be done. my truck is bagged so the ac/heater blower and stuff is gone. and the windshield wiper fluid tank is gone. do they have motor mounts that mount right up? would i need a different tranny? or would it just be eaiser/cheaper to get the 4.3 that my year came with and put that in. i jus need more power. im not lookin to make it fast its just that the 2.5 dont get out of its own way. lol

[TommyC]

someone plz direct me to forum that covers all front caps and beds that will bolt on to a 1993 s-10, including GMC etc. i luv my s-10 and up until a few weeks ago it was in mint condition. i want to just exchance the bed & bumper, and i'd like to exchange the entire front cap to those 80's style with the little square grills. i'd like to go with an all "black" bumper no rubber bumper guard, yet have that plastic spoiler like the late 80's GMC's have. any help would be appreciated. Tom.

i was reading over this tread and didn't see my question but i my have missed it so sorry if its been covered when swapping a 4.3tbi to a 350tbi can you use all the pulley/brackets from the 4.3

[solosdime95]

This is my first time on this fourm and I might not have seen it but what if I want to take out my 95 4.3 tbi and replace it with a carburated(my bad on the spelling) 350 what will not work any more..... ie speedo indicator lamps ect. and what will i need to replace? Thanks for the help

[dieseltech99]

ok, so you're saying that i can drop a 350 in a 99 that had a 4.3 and an auto tranny by just changing a few harnesses and taking out the computer?

[camaro590]

ok i have a 91 s10 2.5 5spd i want to get a carbed 350 v8 and 4 spd trans what do i need to get???

[camaro590]

[quote=camaro590;4336554]ok i have a 91 s10 2.5 5spd i want to get a carbed 350 v8 and 4 spd trans what do i need to get to make the swap easier?

yes you can use all your accessories. the front of the 4.3 and the small block are identical

[1996S10]

I have a question on radiator. What is the best radiator to use in a 96 s10 with a v8? Also i want to keep my a/c evap coil in place so i can use my a/c. I have a single belt system off a 93 chevy full size truck that i'm using. And most of all i don't want to cut it up to fit the radiator.

[sockjock]

I'm thinking of swapping in a carbed 350 w/vortec heads and 700R4 trans. into my CPI equipped 95 Blazer 4wd. What will need to be done to make my guages etc work? Also what about the fuel pump? Will the original pump work with the carbed setup? I'll only be runnin a 600cfm carb and making about 300 HP at the crank.

[2LO4SNO]

if i was to get a lq9 6.0 and it included all the wireing and computer junk needed would it basically bolt right in and would my stock gauges still work? and will a 6.0 bolt up to my stock 5-speed? thanks

[TonyS10]

Sorry about this.. but i didn't have time to read this entire post. so forgive me if i am asking a question that has been asked.. I have a 2000 S10 Blazer 4x4 with the 4.3 that has 135k on it. i wanted to rebuild that motor but a v8 sounds way better. the blazer is lifted 6" with 33's.. I want to make the swap. what motor should i find to make it a smooth swap ?? computer issues scare me.. what do i need for this all to happen easy. lol..

thanks in advance..

305
327
350
400

Now I know you can bore out and everything, but anything it that range will fit with no modification to the firewall. 427s and 454s, CAN be done, but involves more serious firewall work, and is only recommended if you’re really into it. Keep in mind; ANYTHING is possible with Time, Money, and a Welder

-----------------------------2.2 L EFI>>>>>> 350 V8 EFI------------------
Now Ill start off with you 2.2 guys, since your struggling for power the most. First of all, the swap of a 2.2 requires a lot of time and patience. To make this easier, I’m doing a fuel-injected engine to a fuel-injected engine. Meaning there’s no need for gas tank modifications. If you go from carbureted to EFI, or vice versa then you need a new Gas tank unit for the appropriate method.

Ok, now lets start.

THESE PARTS *NEED* TO BE REMOVED-

Engine
Tranny
Radiator
Harness
Computer

THESE PARTS STAY-

Master Brake cylinder
AC/Heater boxes

THESE PARTS WILL BE *NEEDED* -

350 Engine (COMPLETE - IE Alternator, Intake, Fuel Injection unit, ect)
Engine mount adaptors (See links at bottom of thread)
Headers (See links at bottom of thread)
Tranny
Computer
Harness
Radiator
Electric FANS

*** Note, when buying parts, keep in mind what engine you have ect, make sure that your harness will work with the engine, the computer is for a Standard/Auto tranny ECT. Make sure everything’s right B4 you dig in****

PARTS THAT CAN BE USED FROM A 2.2, BUT RECOMMEND REPLACING -

Coolant over flow tank
Washer fluid tank
Drive shaft (will need to be modified if you keep it)
Rear End

Ok. That’s the gist of it. Like I said, there’s A LOT of work involved in it for a 2.2>350. If you have it hired out, expect an easy $3k labor bill, On top of the parts costs.

(Remember you can always ebay that 2.2 and parts as well to make a little income back, some people like all Show no go )

INSTALLING -

If you’re doing it yourself, get a manual from the links at the bottom of the page, and read up. Common engine knowledge helps, (IE what’s where for what purpose) oh yeah, and you need to be able to turn a ratchet . Basically, Run the Harness and computer first. It will go in the same way the old one came out. Your probably going to have to have a custom harness made for some things like gauges and stuff. The Manual at the bottom will tell you all about that. But once the harness is run and installed with the Computer, then you should mount the tranny. This is where the drive shaft modification comes in, depending on what tranny you got, it will prob. have to be shortened. I recommend a new drive shaft, even though the old one IS possible, for a couple of reasons. A) I new one will be stronger, and will fit properly. B) It will save you time of replacing the old one down the road if it does break. You have a 350 now, so your going to want to go fast, that skinny pipe isn’t going to hold up to too much. Once the tranny is in, drop in the big bad 350. A lot of people ask about front spring suspension, I went from 4.3 > 350 with no change in height, 2.2 springs maybe weaker (but at least it will look lower) But once the engine is in, plug it all in, Run coolant lines, ect. And put the new Corvette Radiator in, or whatever new radiator you got for the v8 application. May need some custom mountings, but nothing too bad. And then, hook up your electric fans. I HIGHLY recommend dual 14" fans in FRONT of the core support. Mine work WONDERS and with just a little back notching of a plastic easy to get at grill instead of messing with the firewall to get one between the Radiator/engine. Now except for a few odds /n ends, that will pretty much cover it.

---------------------------4.3 TBI to 350 TBI----------------------------------

To make this easier, I’m doing a fuel-injected engine to a fuel-injected engine. Meaning there’s no need for gas tank modifications. If you go from carbureted to EFI, or vice versa then you need a new Gas tank unit for the appropriate method.

Your job is A LOT simpler in most cases. But don’t let that fool you, its still a chore to do.

If you have a 4.3EFI from 87-93 TBI, if you get a V8 from that same time frame that’s TBI, you have little or no wiring issues, everything that plugs into the 4.3, will plug into the 350. When we did mine, we used everything from the 4.3 on the 350, including Throttle Body, Power steering, Water pump, Harness, and computer. But if you have a vortec, and are switching out, you need to pull harness and computer, and you need a complete 350, as most parts wont transfer. So with that in mind, here are the parts lists -

THESE PARTS *NEED* TO BE REMOVED-

Engine.
(If 94+ vortec to any other 350, Harness and Computer)

THESE PARTS STAY-

Master Brake cylinder
AC/Heater boxes
Tranny
Drive train
Radiator (pull it to remove/install the engines though)

PARTS that will be *NEEDED* -

Engine
Engine mounts (See links at bottom of thread)
Headers (See links at bottom of thread)
Electric fans
Harness and computer (if 94+ swap)
***NOTE, when purchasing harness/computer or having a harness made, make SURE it’s for the proper Tranny and dash setup!!! Hate to plug it in, and not have it work!!! ****

Basically, its the same install path as the 2.2, get your harness in, and computer, install the new engine mounts, then drop the engine in, plug it in, Install headers. Put rad. Back in. once again, I recommend the fans in front of the Core support. Get in and test it out. ect.

****For Both Installations- if you want the fan in FRONT of the V8, and behind the core support, you need to shorten the drive shaft, scoot the tranny back, pound some room on the firewall for engine tabs, and Distributor Clearance, and slide it all back on the Engine mount adaptors. Keep in mind, that’s makes extremely hard to do menial tasks/tune ups, such as Replace Spark plugs, install new Wires, and Run exhaust. ****

Now this was just a ROUGH sketch of a swap, and it answers most questions, with a few recommendations, here are the links for the manuals, and parts -

JTR - lots of people use these guys

Advance adaptors, will have all your answers here too

Any MORE questions, post them in here, We'll be glad to help, plus this will clear out the clutter in the V8 forum, about everyone asking about swaps

Thanks guys, and many happy cylinders!

Ok so I was planning on taking my 305 tbi out of my 88 firebird and dropping in an s10- Im not sure of the motor or year yet. A friend found one for 500 dollars. said he could swap the motors. now what will I need as a must have just to swap it over and drive it? Ill worry about the fine details later like wheels and stuff. I just need to know the must haves right now. My email is Joe1987_05@hotmail.com and if you could help me it would be appreciated.

THANKS
JOEY

v8 swapmounts,headers or manifolds off of a low performace camaro(305).is the MAIN things

These mounts place the motor ahead 2.75", giving you proper clearance at the firewall with ABSOLUTELY NO MODIFICATION, you don't even have to roll the pinch weld! The distributor can be easily removed without tilting the motor (or notching the firewall), and still gives 2" of clearance from the rad to the fan, WITH the rad in the stock location.

As well, the motor sits low enough to clear a tall air cleaner or med rise intake + lowrise filter without the use of a cowl hood.

Oh, and how's this for fit, if you use a 700r4 tranny, the mount will drop perfectly into the hole on the crossmember with, again, NO MODIFICATION or driveshaft cutting.

I got peeved off with all these "kits" that have you cutting, beating, and "adjusting" for firewall clearance and then having you trying to figure out how much to remove from your driveshaft.

Anyone know how to contact k-man? I am interested in some good mounts like these.

this is what I have ""HEARD"" about the 94+ s10 swap.
the accesories off either a corvette or a vortec 350 will fit but a camaro won't
if you use the camaro manifold it will fit just fine
I don't know anything about it but I wish I did....
Jags that run don't (as of last time I checked) offer a book for the newer generation of s10's I wish they did. does anybody know of a site that starts and finishes a 94+ swap step by step with all parts used.. if I could see that I would be ready to go.. but I am getting soo many mixed signals I don't know where to start.

Don't know where or when you got your info, but it is false and out of date.
Acessory fits depend on which engine you are using.
I am planning to use a '95 LT1 from a Camaro in my '94 Noma, and it is a
90% drop-in fit, with the Camaro accessories. Ah, but this is on a 2WD
truck. 4WD is different.
On the JTR manual, I have the 14th edition, which has a chapter on the
2nd gen. versions.
This chapter is also on their website, if you go online to:www.JagsThatRun.com
It is chapter 16. This just includes up thru 97. The third generation...???

[rkmdogs]

On all the threads about V-8 swaps,
I have never seen anybody raise the issue of the speedo scale.
My truck goes to 85mph. The tach goes orange at 4500 and shows redline at 5000 rpm.
The LT1 we are going to put into it will make these values a joke. What is
available and what works for higher speedo scale, and tach recalibrating?

UM YEA,
THERE HASN'T BEEN V8 NOVA SINCE THE 70'S
IN THE 80'S IT WAS A FWD 4CYL. REBADGED TOYOTA COROLLA
YOU MIGHT WANT TO CHECK YOUR FACTS OR LAY OFF THE DRUGS, THEY DO BAD THINGS TO YOU LIKE BELIEVING THAT THERE WAS V8 NOVA IN THE 80'S.

But anways i do have the s10-v8 conversion manual and have givin it a good look through but i have not read weather or not i could transfer all the things off my 1993 2.8L to a 1994 5.7L, Like power steering, alternator, ac compressor?

i've read throughlyout of this thread but one question i've got thats went unanswered....

will the 350's factory A/C compressor clears the hood? i know that the ZR-2 models' will not clears without a 2 inch body lift, but i dont know about the regular S-series... thanks

i think they should. if not you can get the serpentine set-up off of a 4.3, all the holes are the same, but i don't see why they would be different, what application? first gen? second gen?

[s10highroller]

94 vortec 4.3. I have a carbed 350 sittin around. I would like to make an adapter, run a 350 TB on it, and put it in my truck. I'm confused as to whether I can just drop it in and go or what? Will it just plug and play like that?

[Toyota h8r]

Hi all, first post here so please done flame too much

Im picking a 88 4x4 blazer(4.3L/700r4 with non electronic transfer case) and was wondering about dropping a 350 in it. Now i read though the 9 pages and didnt seem to find answers to my questions.

1. 4.3L tbi > 350tbi.....i know the 350 hooks up to the 4.3 harness.....what about the distributer? i mean your going from 6cyl to 8 cyl.....isnt computer not going to able to fire the xtra two cylinders? or does harness plug into the distributer and function properly?

2. how will the drivetrain hold up to the power? I want to lower the blazer and make it kinda resemble a typhoon(ish) blazer. Ive seen a 3/3 drop for the 4x4 and want to do that. Ive already got a 454 powered 77' K10 for offroading.

3. If i were to goto a tpi powerplant.....does the f-body harness hook correctly to the body harness?(for power n such) I know i have to change fuel pump for the increased fuel psi with the tpi setup



I know the basics of a v8 s10 swap....done them before......just carb style. I want to try FI out for a change.

thanks, Shelby

if you have the money you can get some flow out of tbi(for ex. the holly tbi 9000 commander, edelbrock mpfi manifold that plugs into existing tbi wiring)but it is expensive

I'm using 2 pusher fans out of Caddilacs - I had to bend the outside face a little to squeeze them in and I had to grind away a portion of the back of the grill to allow room for the fan motors, but it looks tight and inside the engine bay will be completely clean..

[s10-den]

if you have ac,pusher fans will not keep it cool.Toyh8tr,(1) you will need a v8 distributor(only 6 wires vesuse 8 wires?)same plug if thats what you meant
(2)drivetrain will be OK,but dont go jumping cliffs or moutains..lol
(3)I dont mess with tpi's,unless you just like the looks,the tbi stock for stock is a the best way to go,(just my opinion)I would rather pay $300 for a tbi versus $1000 for a tpi and only gaine 10-15 hp?

[diecast92]

For example, I have a 97 GMC sonoma with the 4.3 vortec and 4L60E tranny. Are you saying I have to change the computer to run a 5.7 liter engine from 1997 and that none of the accessories(water pump, power steering, etc) will fit? I thought it could do this swap without swapping out the computer.

One last question....Can i run a carbed V8 with the 4L60E transmission?

[Brad99Dime]

So i am doing a ramjet 350 swap in my truck and now the problem is we cant get all the gauges to work, how do we get them to work, is it all in the harness??? Becuase thats prolly a little late.... They are unsure if they will work or not, they got the speedo working but what about the rest, will they work or what do we have to do??
Thx!!!

[sonoma91]

im not getting any help with the posts i put up i need info on doing a swap from a 2.5 to a 4.3 vorteci wanna know if i can use the motor and wiring harness and trans out of a 4x4 if they are the same and what else i need to do the swap like stupid stuff that alot of people dont remember please help

[s10-den]

anything that is on a 2.8 WILL NOT work on a 4.3

[leperkuan]

any information on a swap from a 2.5 to a 4.3???

take out motor, tranny, rear end, drive shaft...

drill in new motor mounts???

drill in new transmission cross member???

replace with 4.3 motor, tranny, rear end, drive shaft.

would be nice if the ecu was plug and play??

reason i ask is i have a totaled 92 s10 4.3 and im looking at a 85 2.5 with a blown engine for cheap.

could take forever to wait for a 4.3 s-10 to pop up with a blown motor??

[shadowmoonwolf]

I've been toying with the idea of doing a 350 swap in my 91 s10 blazer 4x4 to replace the 4.3 in it and it is a tbi and has the 4l60 tranny but my main concern was when I started asking around the response i got from the so called "pros" (aka GMC Goodwrench mechanics) I was told they are a nightmare since you have to modify the compartment and get a specific oil pan to fit over the front axle since it's a 4x4. Now so far I'm getting the impression that if i do the swap all i need really is a new 350, an ECM(no wiring though since it's a tbi) headers, electric fan, engine mount adapters and so on...have I got this right so far? and if those guys were right about the oil pans, any recomendations on where to get one that will fit right?(Schucks\Parts America\CSK is preferable since they're my main source for parts up here)

ok, i really havent heard anyone talk about converting a 2.8 to a 350, lol...ive got a 2.8 that will flat out flyyy, buuuuttttt, i want more power, lol, doesnt everyone?....how much will it cost to do this? ive figured around 2,000 bucks? and how hard is it?...the guy next door is a certified mechanic, and he told me not to call him when i get ready to do the swap cause its too hard lol

[skylarkmk]

Hi,
I have a 94 s10 4x4 pick-up with a 4.3 TBI and a 5speed manual. How difficult of a swap would it be going to a 350 TBI?

[lalitopalito]

Anyone know where I can find an engine conversion manual for a 2.2 98 s10 to LS1??

[S10_noobie]

What about just plain ole carb running applications all I see is TPI's , how to get them to work an are they as dependable ?

If i follow correctly all i need is mounts and headers/manifolds. If i use manifolds what year/model do i need them from?

Do i need an oil pan?

And what year/model of eprom do i steal for the new motor? same thing on injectors ive heard/read the v8tbi ones flow more should i get those also?

Lastly i have more access to newer v8's and would rather use them anyway for obvoius reasons, but can i use a newer longblock and just use the older v8 tbi intake manifold and other v6 parts?

thanks please help lol

I wanna say you can run LT1 manifolds, the engine bay is pretty tight in those cars so it'd be ideal that the manifolds are also small.
