I have a 01 blazer with the 4.3, I want to swap to a carb 350. In doing this will i run into any problem with wiring as far as taillights interior light, etc. Since the 350 does not have a computer,also is the tranny controlled by the computer?

[ol red]

this winter ill be doing a 350tbi turbo 400 205 tcase swap into a blazer with 4.3tbi and a 700r4 trans and just wanteed to be sure that so long as i put the 350+400 computer in place of the 4.3+700r4 computer everything will be plug in and run right...correct?

I am looking to make a swap also. I have a 92 single cab 2.5L 5 speed trans in a S10. I am wondering if there are any small block motor that will bolt up to my trans or do I have to get a different trans? I have been reading on here for days and cant find what I am looking for. I believe (from what I read on wikipedia) that I have the 2.5L TBI motor.

Is this an easy swap or would it be easier for me to find a blown up 4.3TBI?

Also does anyone know the code or name of the 5 speed trans out of the 92 s10's that came with the 2.5L? I believe its the same trans as the 2.8...

dpn't trust wiki. you can go into it now and just change anythign you wanna change and it'll show up. i've heard they just changed the bellhousings on that tranny.


i'm being told 2 different thing. that 1) i can just get the comp for the lt1 that i'm using and match that to the bcm that i have in the truck and 2) that i need to piggyback the new ecu to the old one. which one is it?? my truck is a 2000 xtreme if that makes a difference.

where can I get a bracket for the tv cable and trottle cable?

[87chevyblazer]

OK. i'll start off by saying i havent read the entire thread to see if my question is already answered, but everywhere i look to see if i need to swap out my 350's oil pan to clear the IFS. do i need to do this? the 350 is a 69-80 2 or 4 bolt main one peice rear main seal.

Lots of Great information here. Thanks to all those that have contributed to this thead and this site with their vast array of knowledge.

Here is my one question: Could this realistically be completed in one weekend if all extra parts were on hand and ready to go in? The reason I ask is because the S10 is my daily driver so the less amount of time she's off the road the better.

Here's my plans...

1994 4.3 TBI 4L60E to 350 Carb 700R4

From what I've read thus far I'll need the following

Headers
Motor Mounts
Fuel Fittings to connect to the Carb
Guages
and Either a vette radiator or electric fans
and the 350 swap bible

I read through this entire thread yesterday and probably missed something along the ways so please let me know...

Thanks
Bradley

Bradley - I guess a weekend job is feasible in one weekend if you have the knowledge, tools, time, parts etc... however, as with most major swaps there's always "gremlins", as we call them. that you just can't prepare for them, as well as the small nickle and dime stuff like hose clamps, fuel line, or vaccum tee's etc... So I can't rule it out, but I can't gurantee it either. I had all the "essential" parts in hand and started it hoping to have it running/ready to run right away and of course ran into different "gremlins". Such as fire wall modification, distributor clearance, fuel delivery issues etc... And this is just me speaking from my personal experience... the only way to tell is to jump in and get your hands dirty.



Also, As far as gauges, You don't necesarily need new ones, alot of us opt for new ones due to the simplicity of Auto Meter or other aftermarket
gauges...


Hope that helps a bit...

I do know that there is a different oil pan for the 4wd's. Do you know which oil pan do you have?

I bought a universal one for a carb @ O'reilly. I belive Spectre is the company that made it. Or you can go to the junkyard and find them on an older v8 truck as well....

okay, ive read just about all of this thread and i still cant find the answer to my questions.
i have a 95 ext cab its a 4.3 5sp 2wd
its tbi and i want to but a 350 tbi motor in it . im keeping it a 5sp.
my question is will everything plug in and run good. ive already made my tbi fuel pressure adjustible to solove the problem of it runing lean.
and it has obd II .
i had a 92 4.3 5sp and the only diffrent i see in the two motors is that the 95 has diffrent valve covers and trimming chain cover.
im planning to do this winter and get it done as soon as possible.
will everything be about the same as a 1st gen swap???
any help will be thanked greatly.

[KDsS10]

Here was another extremely helpful link concerning the rear, for anyone doing a V8 swap, outside of tranny DONT FORGET that 7.5 grenade...This link details an 8.8 (yes blue oval) rear swap that is very cheap and easy..but the benefits are awesome..just wanted to share.

i used 1st gen v8 kit it worked out fine i had a 95 ext cab with a 2.2 5 spd and went to a 350 and turbo 350 trans i had to trim the ears off the trans and that was i did away with alot of wires and it ran great all the accsesoories worked and all that now im about to start a 83 ext cab and go for the 350 swap

[94Sonoma94]

So heres what i got, 2.2 coversion to 5speed 355 carb.

Motor mounts
V6 Tranny/driveshaft
custom mounts
Custom headers/manifolds
radiator/essential plumming

wat am i missing, i feel like i need more.

[twiztedazz]

ok i have a 1997 s10 and i'm putting in a 383 stroker with a carb do i need any of the wiring i'm going to be runing a mallory dis. and coil and a 350 turbo tranny the block is punch out 40k

[94sdime350]

My truck came w a 350 combo. I have a 350 tpi all aluminum w 700r4 w harness and ecu. Besides fuel pump what else do I have to change? What about sensors? And exhaust clearance w tranny? The 350 in my truck now has an oil pan leak and a tranny coolant line leak. So I think its time for a change. Any help would be great.

[Bouche]

ok i just dont get the concept of swapping the computers and harnesses. not the functionality part but how you do it. help

[Revolt]

Go to your local junk yard and ask if you can watch the proper removal of the ECM harness. If you have a local pull your own part yard go and have a look at the ECM harness and how its installed. Not a whole lot to it, really.

[94sdime350]

Here are my mounts. They are fabbed. No kit. Hard mounts, bushings.

[jgreen]

I have a 2000 s10 2.2, automatic, im looking into swapping a 5.3 in it so i want to aquire some parts when i can, i know i need a tranny computer harness etc, but should i do fuel injection or have a carb?

[94sdime350]

With fuel injection you can reuse some stock s10 parts from the fuel system. Like the fuel pump and pressure regulator. With a carb thats all gotta go w the swap. But a key point I need to make is w your truck being a 2000 model year. inspection might be an issue in your state. In NY we need to plug every car after 1994 into the computer for inspections. You cant plug anything into a carbed motor.
If you do go w FI check out painless wiring they have a harness for the 5.3 motor. It will make your FI swap go so easy. and i think they can do custom ecm flashing for heavilly upgraded motors.
Good luck w your project.

[1994dime]

ok i just wanted to clear this up for myself, if you use the computer/harness from a 4.3 wht exactly has to be done to it for it to work good with a 350?
