no u cannot use the computer or wireing harness. well the harness u technically could i guess jsut add 2 injectors to it and use a v8 computer if the connections are the same i don't really know. but all the 4.3 is is a V8 with 2 cylinders cut off. so u sould be able to use the scceceries but cheak that out more i don't know that.

wow, lets do our homework a Throttle Body Injected vehicle has the injectors at the Throttle Body.

o hey sry...lol...i read it as tPi...alright well in that case then iono..iono crap about tBi...

[350*s-blazer]

all you have to do is swap in a new p.r.o.m. chip and extend the knock sensor wiring and O2 sensor wiring. 4.3,5.0, and 5.7 use the same throttle body the only diff. is the injector flow rate, and there are only 2 injectors,ohh and thay all they also use the same computor just diff. p.r.o.m. chips

i gotta question for TBI people....whuts the point of a TBI engine? y not just go the little bit extra mile and use TPI? i mean in my opinion they look better, have more power(suposivly) and get better gas milage? i mean its not THAT many more wires

[Joedirt3]

whoever wrote that first post on installing the engien had it all ****in ASS BACKAWRDS....put the ****in engine in first THEN the tranny THEn the harness...and the firewall doesn't nede to be modded that much to get fans in the back of the rad...also electric fans don't cool as well as an engine driven one...****in dumbass's...also i've NEVER heard of a driveshaft breakin....unless the ****in thing is built up to all hell....which i doubt mot people are ganna have.

back in 1994 when i lived in Tacoma, Washington, I had a black 85(I think)S-15 Gypsy 4x4 with a very nice suspension and a full roll cage inside the standard cab...the guy I bought it from said the V8 was out of a Corvette and the 700R4 was out if a Camaro(back then I didnt know or care)....but the engine died one day and the guy I bought it from was no longer running his lot...so I had someone else pick it up for $3500...now I have a 92 Blazer(4x4) with a 2.8 and a 5 speed....I'm going to get the JTR book and start looking up what it is I will need to convert to a small block(with an automatic of course)....seems that the S-Series community is at odds with each other about V8 swaps...I think GM should have done this years ago...Dodge did with the Dakotas....there are a couple of swaps here in the El Paso area that are pretty nice, but I have yet to talk with them about what they did and how they did it.....I'm not done researching this though....

Ok guys, here's my deal. I'm tyin to convince my dad to let me put a 383 in teh old s10 instead of gettin a new truck. My truck has a 2.5 5sp and is a 90. Can i reuse any of the parts from it?? What type of motor mounts will I need??? Can I get the stock speedo etc to work with it?? Could somebody do a part for part what I'd need to do it list like is at the top for the 2.2 and 4.3?? This is what I wanna do to it but before I really try and work on him about it I wanna have all my facts in line and as close to EVERYTHIGN that would go int doing it. Thanks

[XtReMe_CaNaDiAn]

although this entire thread has been very insightful on V8 swaps, I still have another question, I want my '03 xtreme to kick ASS! but the v6 isn't doing it for me. I was think a 5.3L Vortec V8, Any insight?

[FARRAR]

ok i have a dumb question. I have a 86 s-10 blazer with a 2.8l tbi. I am putting a 350 with a turbo400 in it. how do i get the fuel to the engine. Can i use the stock intank fuel pump or can i just use the manual pump on the engine. also if i take out the computer wont that affect my guages

[350*s-blazer]

well tell me somthing. first off all you do is talk shit souldn't ur pussy ass be working on ur swap??? cause i know i never had time to dick around and talk shit. and another thing why did you piuss out with ur tbi a lt4 or a ls6 has a lot more power than a tpi and looks ****ing badass and has a lot more potential??? ohh what u could afforda engine out of a wrecked corvette?? or u just couldn't find one locally???
well a tbi is cheap availiable and easy and sheap to get more power out of. i have a question for ur ass why the **** arn't you out in the garage puting ur energy into ur truck instead of useless posting here are benifiting anybody by talking shit??? well i know i;m not the only who is tired of seeing ur posts and talkign bout another forum again i ask u if the other forum is so badass why arnt you there instead of here???

i was wondering. i want to drop in a 88 359 tune port from an iroc. i have the topend plus heads,harness, and ecm from the iroc.

its going to go into a 93 blazer 4x4 4.3. with the 460le or whatever its called tranny.
my ? is will a painless harness let the tranny work with ecm?
or is it easier to just swap in a 700r4?
will the factory 4.3 frame mounts work to bolt up the 350?

i did a quick search, but still nothing

my fairly mild but everything new 400 small block swap cost about 5000.00 when all done including exhaust transmission and all.this is a carb engine swap into a first gen.it really depends.ive seen some guys do the swap for 1500.00 and up.

i belive the tranny will be fine however i think you will have to change to the 2.8 lower mounts depending on the upper swap mounts you use.

[syclonekid43]

i have a set of energy poly mounts from a 350 that i was gonna put in mt syclone.i was thinking of using those.

QUOTE=Beeker]In most cases, No, I highly reccomend headers for a decent fit, and better Access to Spark plugs. With the headers, the steering shaft goes between 2 loops in the drivers side header, and Im pretty sure if


they were manifolds, it would not fit, or rup horribly[/quote]

[s15beast]

what kind of headers would you put s15 84 dropping a 305 all dun up and what kind of radiator

[95thndr]

O.K. I read the whole post and am not sure of the answer. Does anyone know what it would take to put an LT1 engine in a 1996 4WD Blazer? Can I use the same transmission that is in it? It had a 4.3l with the 4l60e. Will I have to do any modifiying to the trans mounts or transaxles. It looks like all I need is mounts, ecm, wiring harness, engine, rad., fans, headers. Is this correct?
Thanks,
Scott

[shrtyscrw13]

i was just wondering about the stock transmission and differential in a 1991 4.3L Blazer and whether or not it can handle a 1991 or newer 350 or not. thanks

It's a fairly easy swap, you don't have to modify the tranny mounts or the axles. You do have to get an oil pan from advance adapters, that will fit around the front axle, they are alot cheaper from summit-they have motor mounts also. Then you will have to make your own oil pick up tube, because an lt1 has a bigger one than a regular 350. A lot of people get by with the 4.3 radiator, you could try it, and if it heats up, buy a bigger one later. You also need to have the ecm that came with the engine flashed. And you can use your tranny.

If you have an automatic transmission, then it is the same one that is in a half ton pickup, and yes the axles can take it.

thanks blazerblobs, .

Advance adapters has a manifold style header that will clear the steering, but if you want real performance headers, you can get sanderson or hedman headers, on those the steering shaft goes through the header. The rest of the swap is pretty easy.

I have an early 1985 s-15 jimmy 4x4. My 2.8 has been replaced once and it looks like it needs to be done again in the summer. I know what i need for engine and exhaust, but as for tranny and rear, im stumped. the 85 is carb'd and no computer stuff at all. My problem lies in these computer controlled tranny's. I want to use the earliest 700 r4 that bolted up to a 4.3 (90 degree bellhousing) but i think that all of those tranny's had some sort of electronic or computer control. im trying to preserve the use of the old 4x4 and column shift system. I would gladly use a TH350 if i knew it would bolt up to my transfer case and crossmember without much modification. any help would be appreciated. Oh and i want to put in a posi rear with disc brakes but im completely clueless as to what would swap directly in. thanks guys

[S-10_Stewart]

ok iv got some questions,
can the 4.3L computer be tha same for a 350?
can the rad stay I dont want to spend $400 on a custom one?
motor mounts can the be reused or are new ones needed?.
I know about the oil pan and the headers is Advanced Adapters a good place to get them?
and the ac must have ac.

Thats all that I can think of that others have not thought of or they may have to do if they decide to swap their motors. But mostly for me I got a motor out a 90's suburben with a newer 350 tbi.
thanks Anthony
