Swapping? Heres A List Of Parts And Answered Questions!

[PRUSHIII]

HELLO GUYS, I am currently building a 383 LT1. I bought it out of a junk yard with the tranny for $250. After $600 in machine work and the new crank given to me by my boss, I am starting to get it put together. My question is, will this motor be worth the effort with the stock iron heads and intake manifold, or should I go ahead and invest in something better while I still have it apart? I want it to be fast, but it will still be a daily driver for me, so I dont want to go overboard. Any imput would be appreciated.

[Buddha..]

If you wanna make big power the stock heads are not gonna cut it.

If it was me though, I'd try it out for a while as is.

02 S10 xtreme with a 2.2l and a 5speed. I want to do an Ls1 swap with a 6speed from a camaro or a transam which ever i can get my hands on. I know that the transmount will have to be modified, and the trans hump will also have to be modified to suit to the different size of the tranny. My question is how different is the wiring harness from a camaro or transam compared to my s10?

[supasoulja]

I REALLY want to do a 350 swap into my truck. I have a 1995 chevy blazer 4.3l vortec with a 4l60e and its 2wd 4dr. I read if its vortec i dont have to change computer/harness then i read somewhere else that i do need to get another harness/computer. I really want to do this, but i only have 1 car so it can't be down for too long. Can someone tell me if i do need to change comp/harness or not?

anyone?

[s10-den]

I know a guy who is still having problems out of his 94 4.3 to 5.7 tbi swap.I dont know because I only swap out the 93 and older ones.I have heard this befor on other 94-95 swaps too though

[Flaw]

I like the idea of v8, but S10 V8 seems like too much time and money ( for an S10) But on the other hand, this would complete the package. I have an LS1, but I am not sure if it is worth it (to me).

I dont know,,,when I think about it, it sounds nice,,,but on the other hand,,,if I want to go fast,,,I can go fast on my bike and just cruse with the S10. I dont know,,,

I'll give it some time and maybe I'll change my mind (get the wind up my ass captain) 0_o

[sikpaintant]

has anyone done a v8 swap on a body dropped second gen with sd control arms?

i got the motor in my truck just not real sure what is the best route for headers/manifolds....there just isnt any room....i know i will have to cut my firewall some more but if anyone has attempted this yet some info would b helpful..thanks

[lowtruckinjy]

what about 2.5l to 350 swap?

[shaynel18]

what kind of headers are best to get for a jimmy doing the swapp. i got a 4x4 98 jimmy what should i get for headers, and will the rest of my exhaust work for now till i get the money to go true duals, and full exhaust with it

Anyone know the length of what the 97 2.2 5 speed driveshaft needs to be shortened to in oder to use a 96 impala ss auto trans with the LT1 engine ? Its a reg cab short bed. Oh and using the stock x-member with stock transmission mount on the closest to the front mounting spot on the auto LT1 trans.

Your best bet is to just put it all in and then measure, It's the only way to get an accurate length.

i have just bought a 1993 s10 and i want to put my 350 in it. It currently has a 4 cylinder in it i was wondering how hard it would be exspecialy sence im going to be changing from tbi to carberated. is there a manual i can buy or does any one have tips

[87SS10]

can someone tell me what i am going to need to do to put a 350 in a 87 that has a 2.5 in it now

read the first few pages of this thread, then search on here, the info is all there.

[daddytech]

There is a mont kit that you can buy to keep from having to beat the firewall back or cut it out. A friend of mine in Georgia actually did a 4 cyl conversion to a 350 HO out of an older Z-28 he used two lef side motor mounts out of a 72 chevy nova and set the motor down level in the engine compartment and was still able to use a flex fan on the truck and it worked just fine. I am told that summitt racing has a mount set that can be used with the same results.

I am fixing to have to get a set as I am putting a 350 4 bolt main in my son's 1988 S-10 Blazer with a non computerized turbo 350 transmission. we are converting it not only to a V8 350 but also taking it from 4wheel drive to a 2wd that is making life all kinda fun for us too as we can't get the front drive axel out without tearing the whole front end out from under the truck.

I have a 96 sanoma witha 5 inch bodydrop there is no wiring in the truck at all I am wanting to put a carb 350 into it and I need a harness I talked to painless thay say thay dont have anything for me . all i want is to start it and run my automeater gages thats it. some help would be nice thanks .

[slammedcavi]

I want to get a 5.3 out of a 2003 silverado, but I want to get a manual tranny. Is the t56 the only manual?? Also, with the tranny, waht computer will I need to use?? I know they didnt make pcm for a manual silverado....


Edit: Its going in a 2.2 manual s10

[bw2358]

Ok, I know it's prolly on this site somewhere I just can't find it. I have a 1994 2wd 2.2 4cyl 5spd. I wanta swap in either a 4.3 vortec or a plain 4.3. I'd like to know which one will be easier to swap in and easier to find in a salvage yard. Any extra tips would be great!

Do you have electric window? you need painless Part# 10202 18 Circuit Universal Harness / Non GM Keyed Column with gauge harness kits,30301 or 30302 for your stock instrument panel. If use an electric cooling fan make sure to purchase a cooling fan relay kit such as 30114 or 30115

what do you want a T5 5spd you would need an adapter plate?
you can get the new 6 spd auto 6T70 or 6T75.
the only computer you need is for the engine...the manual only has sensors and switches...the auto is the one with its own computer

the 4.3 is easy to find...to find a good low mileage one is hard.

if you are going to spend the money and time the vortec is the way to go. most have lower miles and run better. just make sure you get the ecm and harness. you would also need a s10 4.3 harness and cut and make them work

Stupid question, what rad hoses do I use?

[1st-timebodydrop]

ok i have a question i got a 302 block,heads.new pistons.30 over ,mild cam with lifters and roller rockers also a rebuild kit for free and i was thinking about putting it in my 1st gen 85 s10 now i do understand that i will have to pretty much gut all my chevy drive train make motor mounts and cross members and possibly have a driveshaft made also the fact that it is a ford motor going into a chevy i am throwing the idea out there what do ya think worth the work??

[The Griff]

I used the stock 4.3 hoses, had to trim the upper, but the bottom one worked fine

You'll get mixed replies on this. I don't think it's worth the hassle. i'd say sell the 302 & buy a comparable sbc. Since the parts for the swap are already made. But then again, if you feel adventurous & want to take on the work, go right ahead. it's your truck.

ya i think that is what i am going with because today i also found out that where the oil pump on a 302 is on the front and in an s 10 that is right where the front crossmember is so i think i am going to clean it up and sell it

[83blazer28]

OK, Just throwing something out there, this is a pretty incomplete "what you will need" thread, they have 2.2Efi > V8Efi and 4.3Tbi>V8Tbi, what about 2.8 carb to V8 carb?
or 2.5 > V8?
everyone says "read the sticky!!!!!" well in my opinion it is almost useless unless your doing one of those two swaps

Carbs are easy, I just unhooked the stock pump, ran a mech. pump off my block & eliminated the ECM. Just got the wires I needed from the harness & cut & tucked the rest.

i'm in the same exact situation. sfbd'd, sd control arms, 350 v8 in a 2001 s10. got the jtr mounts and have the motor all the way forward and i most certainly have to hack up the firewall for header clearance. Anyone got any pics of a simular setup? btw, how was the exhaust tubes run under the cab? I've got the transmission tunnel built, just got slapped in the face with the reality of "i need room for exhaust under my truck but don't have it." Anyways pics would rock.

[D-LoW]

[The Griff]

you'd almost be better off searching in the Bodydropped section. the BD guys usually stick closer to that section. However there is some information here, there is also more BD trucks in the BD section of course. Just search both sections for best results.

[D-LoW]

thanks man.

I have a 2000 S10 with a 4.3 and wish to put in a 350 tpi out of a 88 IROC Camaro. Has anyone ever done this type of swap? Any help or direction would be appreciated.

you name it, it has been done

first off does your state do emissions testing?

it can be done, just need the proper wiring setup to make it work

[Dizzle]

Yes it does have emissions testing but the iroc passed them plus the guy that does the testing is a good friend of mine so i can pass if its bad. Do you know the wiring setup I would need?

[01x.joyride]

what bout...an 01 vortec 4.3L to a 350 vortec and/or non-vortec because my dad has a block heads and a 400 crank just laying around?? 383 much? lol.
and what about emissions? what kinda 5 spd trannys fit onto a v8 in our s10s? im pretty sure running the stock nv3500? i think it is, wont hold up too well right? thanks in advance!

ive got a 86 s10 wit a 2.8 im going to put a 5.7 in it probly with a th350 the common swap but will i need to cut the firewall for this

Also with that automatic I'm going to need to have a floor shifter comin through where my stick shift used to be. Is there any place that makes a box of some sort to keep dirt and crap out for under my truck. I'm sure there's going to be a gap between the top of the transmission and the floor of the truck where the shifter goes through.

Josh

the 350 trans in a 3 speed,it will also make the enging tach higher rpm,,use a 87-93 700,,they have the best of both worlds,low 1st ,od,and lock-up converter,,as for the hole,get a piece of sheet metal to cover it ,,screw or weld it in,,then get a b&m megashifter

[sirlazarus]

Hey. I am new to this board and have recently acquired a 1992 S-10 2x4 with a 4.3L TBI with a 4L60-E trans behind it. I do plan on putting in a 350 engine and 350 trans (short tail) in it sooner or later. Curious if I need to make any mods on the driveshaft. And I was told that the 4.3 is a 350 but with 2 cylinders cut off. If it is then one would assume that you don't need to change motor mounts, correct?

[ZacharySmith1985]

if anyone can help me out i need some help i want to swap my 4.3 out with a 350 but i dont know if i can cause my s10 is a 2000 and the motor is older like from 85 86

Cut the firewall? NO, for no reason should you have to cut the firewall, IF you use motor mounts like what summit or jegs sells for the s-10 v8 conversion, they allow you to have the motor slid forward in the engine bay or backward in the engine bay. since you say you have an 86 and are going to 5.7 with a turbo 350 can I assume you're going to be running carbed and not FI? If so I personally would slide my motor in the rear position in the mounts, massage the firewall on the passanger side for collector clearance, run a billet distributor OR run a points distributor that's been converted over to hei with a petronix kit, that way you have some clearance for distributor at the firewall. I've done 3 gen 1's and never cut anything, You shouldn't have any issues or the need to cut anything except maybe the core support to put the radiator in the forward position.

I have a pic attached, and you can see the fit is fine, no cutting anywhere on mine except the core support.

[quote=tjwenger;215824]Ok Boys and Girls, I know a lot of you have questions on doing a swap out of your poor 4 bangers or mere 4.3s to run with the pride of having a V8. First Id like to Say, YES, it can be done. Here is some Common known engines that will fit.

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 We

-----------------------------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![/qu
