I would like to know what the swap procedure for the 2.5 Vortech with a TBI is, is it the same as the 2.2 or just what.

Its a 4 cylinder. The same things are required for a 2.2L, 1.9L, and the 2.5L.

i have a 2.5 89 s10 and want to convert any one have 2.5 to v8 mounts

After reading thru this whole thread I was able to find the answers I was looking for. Any chance of more people posting pictures. I have seen some swaps that were clean, and others that looked really bad. My 91 is needing rings, it starting to smoke, so this looks like a good time for an 8 swap, just happen to have an 88 camaro out back:thumbup:

And for anyone that is considering the swap that doesn't have a 4.3 now, you will have to change bellhousings, or trans, the 2.5, 2.8's have a smaller block, I went thru this with an 85 camaro, went from a 2.8 to a 350 with factory 5 speed, back when I did it, it cost a fortune and wasn't worth it.

[madscientist]

ok i have an 89 s10 ext. cab it currently has a 2.8l 5speed its the borg warner t5. my friend just gave me the truck.it also came with a 305 the mounts i need and the full exhaust i need to do the swap and a bellhousing from a 82-92 camaro which clutch and flywheel do i need to keep my t5 trans.

[timw48030]

Ok I have a 88 s-10 with a 4.3 auto trans that I just replaced the motor but would like to swap in a 305 or a 350 tbi from the same time frame.I would like the cost down I would like to use everything from the 4.3 p.s a.c ect my ? is what exhaust manifold can I use to fit the stock exhaust system?also what would be a better doner a car or a truck? Also and what other mods do I have to do other than the motor mounts for this set up.

[Daveman2]

Obviously if we do an engine swap, we have an engine left over, what's the resale value on a '98 70k Vortec 4.3L with no internal modifications? Just a removed Maf Screen UD pulleys and cut TB Plate? Like if i took it to somehwere, how much $$$ would i get

[loud91]

alright im probably gonna get a late 80's rebuilt nova 350,will the prom, ecu/ecm and everything will it all hook up no prblem?

[moonshine]

I would like to know what man trans i am going to need for a 305 for my 82?

[F-*-C-K-E-R]

Ok unlike some of u. I am a mechanic for a living. I plan on puting a 406 which i have the short block already . 95 s-10 xtnd cab i think i put pics somewhere hell who knows i get lost in this damn forum. anyhow i honestly havent seen any second gen swaps i mainly am curious of clearence issues. i am going to make a front motor plate i got the earlier style headers which i think will work. being as such i used the earlier style spindles on it to drop it. Has anyone done this swap PICTURES would be nice. i will probably end up going the digital 6 ignition route with the small diameter distrubutor. I watched my neighbor do a ls1 into his 32 ford swap and what apain in the ass that was. so unless i can find the marine fuel injection that has the vortec heads on it very similar to the ramjet setup wif out the ram jet intake. very simple too no o2 sensor no emissions bs. I will go carb rather have injection being that already have the pump. etc but who knows. i am curious of one thing. the t-5 in it which i have put these behind small blocks etc and they seem to hold up. but i have done some modifyinjg tomake em fit. if i get a 4.3 bell housing well input shaft still line up etc. correct depth etc i am pretty sure this is the 14 spline input which i can get 88 astro van wif a 5 speed 11 clutch disc so thats covered. but i wanna use the factory clutch setup. master cylinder etc. and then when that blows up i am going 200 r4 not as low first gear. and not that aluminum drum that the 700's have. also lower over drive in the 200's anywayz if u got any input luv to hear it thanks. Oh anyone done any big brake setups on these. I wanna do 14 inch rootrs on front and 12-13 on back. which leads me to the last thing on my mind supposedly u can get an 8.5 rear out of some of these trucks. but finding this elusive creature has been a lesson in futility. is it zr-2 only or??? enough rambling for now...

[owiseone35]

I want to swap out my 2.2 for a 350 as cheap as possible, but I am not sure where to start. I want to eventually have a street strip truck capable of running 8's though for now i just want a cheap conversion. what trannies can i use if i want a manual. also what about gauges if i want it to look stock?

[sdimess]

Hey everyone- Well i got my engine installed and and almost running thanks to this forum but i'm thinking i took a wrong turn somewhere. I had a 94 s-10 4.3 with CPI and i'm installing a 89 built 350 TBI with the 700R trans. Only thing i can't figure out how to get to work is the injectors on the TBI. Theres fuel pressure up to the TBI unit but they won't spray. The computer has power and when i bi passed the wires for the TBI the injectors sprayed. The only thing i can think of is that i missed a wire hook up or something somewhere for the computer. Another thing i was wondering is if the fuel pump was supposed to start pumping as soon as you turn the key before you start the vehical, and if it is would you be able to hear it. Thanks for ne help ne one can give me.

I have seen a lot of talk about the older body style. Does anyone have any exprience with the 2000 or the years similar to that. I need to know what needs to be done to get the motor in there. The truck is a 2.2 5 spd. I can do just about anything. I do alot of GM swaps threw this site..... www.l67swap.com

this is the stuff i have questions on:

motor mounts
accessories
drive shaft
wiring
PCM
exhaust

Well what engine do you want to sawp in? Motormounts will depend on that. Also, as far as the accessories, it depends on where you want them mounted. If you'll be happy with the factory serp setup then that's gonna run ya about $750 w/ ac. Do you want to keep ac? Driveshaft may or may not need to be shortened depending on engine/trans placement and your choice of transmission. Wiring, are you going to stay efi or switch to a carb? Pcm, you'll need it from whatever vehicle you snag the engine from. If you go carbed I've found this site to me the best. www.ezwiring.com ...Exhaust is also dependant on wether or not you want ac. I've got hedman shorties on mine. Hate them with a passion. Collector leaks...flange on the driverside will not seal worth a damn either. I've looked into the high $$$ ones, but they exit fender well style, so if you're lowered with wide tires that ain't gonna work. Not to mention I am sure you could find a local shop to custom build a set for you. I am, and it'll cost me $750. Long tubes, 1 5/8 primaries and 3" collector with 3/8 flanges. All stainless steel. I'm probably gonna make this guy wish he hadn't quoted so low, as I was a custom fenderwell exit And I've notched the firewall already to give me the clearance

[skynyrd4214]

wow this post is long! anyways my dad has a gmc sonoma, i beleive its a 91, possibly 89.if i buy it from him later on i would want to swap in a 350. ive heard that you can use the stock tranny and radiator, and you also said that in the first post, i beleive. I was thinking about buying a gm crate engine package off jegs thats relatively cheap, (2000 or so) and includes the motor, an edelbrock performer intake manifold, an edelbrock 600 cfm carb a hei distributor and some chrome peices.i was just wondering what changes i would have to make to the wiring and computer? would i have to buy an all new computer/wiring harness if i chose to go carbuerated? how much could i expect to spend if i did have to buy those. i know you said that if you go carbuerated you have to get some kind of new gas tank epuipment? what exactly do you have to get and how much might that cost. thanks

[BadAss_S10_2002]

It has to be a 4.3L truck for the trans to "bolt" up. Don't mean its gonna hold up. That crate motor ur talking about..Is it the 260 or 290 hp version? If you go carbed, you take out the ecm and its wiring harness altogether. Factory wiring for everything else stays in place unless you feel the urge to redo the wiring completely. I doubt a 4.3L rad will keep it cool enough. Mine had the 84-86 Vette rad and 2 huge puller fans and 1 pusher. With a 190* thermo(I like to have use of defrost in the winter), it'd creep on up to 210 idling with all fans on. I'm looking into something a bit larger..while setting the engine back enough to use a engine driven fan. I dunno about the newer intank pumps and that sorta junk, as I had an 84 with a mech pump. Total cost on all this stuff..Every little nut and bolt included...$5000 easy. If you don't skimp and buy the right thing the first time.

[VT1992 S-10]

I have a 1992 4.3. I am in the process of buying a late 70's 350 carb. engine. I want to use the tranny that is in it 700 r4, which is electronic right? what would I have to do to make everything work together?

Trans will bolt up. Its not elec. Buy the swap mounts+headers of your choice. Everything has pretty much been covered already tho

[autotech]

what about the oil pan???

[autotech]

sorry, what about the oil pan for a 4.3 - 350 swap???

[350*s-blazer]

only if you have a 4x4 or if you are going with a ls1/ls6
the cheapest price i have found for the 4x4 pan is around $200 from www.v8s10.comhttps://shell7.tdl.com/~jags/S-10_Order.html -link to parts list

[hndaklr]

hello, i saw a bunch of older s10/sonomas being coverted, what what about new(er) ones like a 99? im framiler with the junkyards in southern ontario regions too, but where can i find a computer, and how much money can be spent on them..
I haven't bought a s10/sonoma yet, but first i have to figure out the cost of my honda killing, rice frying, punk smashing 4.3... before i make up my mind... school + truck = broke..
Thanks -- Ian
.....i loath hondas.

Thanx for the link, I think I am going with the oil pan extention, I like to weld.

any thing else you can come up with, It would greatly help, I am doing this project to piss off the wife

[350*s-blazer]

Throw a supercharger on it, lift it or a suspension swap.
and when you break in your cam make sure its real late at night or early in the morning.

[BadAss_S10_2002]

Yeah I know all about that shit haha. I had just straight piped my truck at 3 am, after swapping water pump/radiator/fan. My neighbors hated me from then on...2.8L V6 with nothing from the manifolds back but 2.25" tubing...God I miss those days

actually if you use a 4.3 tbi computer and chip on a 350tbi it will run rich, that is as long as you have 350 injectors in your t.b. if you need to know ecu #'s to get for the the swap check out

www.tbichips.com
there is a page there about swaps and computers to use he also does tpi i believe

[gregsgreenmachine]

I've seen this asked, but not directly answered... do I need motor mounts for a 4.3 to 350 swap? and where can i get them, I've only managed to find 2.5 + 2.8 mounts for the swap.

[350*s-blazer]

no get the 2.8 to 350 mounts(these are just brakets,peferably stealth mounts) then go to checker and buy some stock or poly 2.8 motor mounts(these are the actual rubber mounts) the 2.8 mounts are similare to vetee mounts and are way better than 4.3 mounts then do yourself a favor and buy the manuel they have picture and cover the details, they don't cover fuel injection too much but they do have modifactions for lt1-4 ls1-4...ect. it is reallly worth the $30 compared to how much you are spending on the swap

[K-Man]

I will be pulling the motor out of my 87 in about a week or two and when I do, I'll have to take some photos and measurements for all you guys interested in saving a few bucks. I always use stock 2.8 pads on the frame and I have my own mounts for the engine. the mount I run are made from a set of stock v-8 mounts that I modify. 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.

[K-Man]

Oh, there's actually still a pic on here from when I used to visit quite regularly. It's not the greatest photo, but it does show how the motor sits. There's a few other pics of the truck too.

[BadAss_S10_2002]

Yeah deffinately post pics of those mounts. I'm looking at all options right now, after hating the hedman shorties+mounts bs that I had in mine.

Funny you should say that, because I also forgot to mention that they work awesome with hedman shorties. In the pic that I sent the link to, I'm running stock cast manifolds and they still clear....mind you they're close.

[fetuss10]

thanks needed the info from this thread

[BWAceo2]

I live in Phoenix, Az and drive a 96 s10 extended cab with a mighty 2.2 litre engine and I want to swap it for a 350. I actually would like to do it myself, but I have no experience what so ever with engines and lack the tools, all I have is a screwdriver, phillips... So I was wanting to know if anyone knew of a shop in Phoenix that will install a 350 in my truck and do it correctly, and how much it will cost, roughly. Any help would be greatly appreciated, thanx

[TCrast]

hey guys, i have a 305 that im planning on rebuilding, a th400 tranny, and a np208 tcase that i want to put in my 89 blazer 4x4. i just want to know what parts i need to pick up before i start tearing the 4.3, 700r4, and np231 out. im sure with the changes i'll need to get new drive shafts too. im also planning on swapping in a dana30 up front rather than the P.O.S. IFS that is constantly causeing problems.

[MilkBox]

anyone know a link to a website where i can order mounts to go from a 4.3 to a 350. ty, once i get those i will post pics of the process, my goal is to do it in one night.

Here's a good place to start: http://www.tdperformance.com/TransDapt.html

They've got kits for a few s-10 v-8 swaps. GOOD ones!

[MilkBox]

cool thanks that saved me the trouble

[blazeboy]

what if you have a 4.3 vortec and do a 350 vortec conv., could i use the same wireing from the 4.3

[K-Man]

Quote: Originally Posted by blazeboy

In most cases, yes.

[blazeboy]

yes i could use the same or yes i would have to change. Also what do you mean by most cases

[longarm1]

u from columbus should try crestline junk yards (near mansfield) lots of late modle

[K-Man]

I know the following link will not help you, but it might help others that are thinking about putting a vortec SB in an old s-10. It has really good instructions on adding an EFI vortec engine in an older carb setup. http://users.apex2000.net/whardie/wiring.html

As for your swap, yes, you can use all the same wiring, computer, etc. As long as the donor engine is from around the same model year as your s10. Me and my buddy pulled the 4.3 from his 91 s-10 and dropped in a whipple supercharged (aftermarket) vortec 5.7. We kept the factory 4.3 wiring harness, computer and trans. we didn't have to change anything, but should've swapped out the ECM chip for an aftermarket one to take better advantage of the whipple.... But then again, when you are cranking over 380 horses with a 5 speed manual in s truck that only weighs a little over half that of a fullsize c/k pickup, what's a couple of ft/lbs of torque at 5500rpm...

BTW, this only works if you are swapping from a TBI 4.3 to a TBI 5.7. If your 4.3 is a multi-port model, you will have to change out the harness and the ECM.

[blazeboy]

well it will be in a 98 blazer zr2 with the vortec 4.3L if all i know right now, i'm buying it this week.

[itguy1984]

I DID read this thread and No one seems to know much about the 4x4 set up. I have a 4x4 s-10 1990 and i am looking into Pulling the 4x4 stuff out of it and going 2wd. Is there any real diffrence when it comes to where things are mounted and what will i run into when i go to put it back to 2wd and put the V8 in it?
