i've got an 80 chevy luv that is all stock currently. I have just been given a 92 4.3 that was bored.030 over with 350 flat top pistons and a 700r4. I am in the process of getting the harness and computer to make the tbi work. I was wondering what else needs to be swapped and how diificult the swap is. please contact me if you have done this swap, i need alot of help

This will be a good and a easy swap,all you have to do is the same as the V8 swap but you will have a whole lot more room to mount the radiator.Look up the V8 350 swap info and you will have a pretty good idea on what to do and i think the manifolds will fit with no problems to as for headers Downy toyota makes headers to fit toyotas and they may work.

how would the 5 speed go in as far as shifter placement. Would any firewall modifications. I have the 700r4 but this is my weekend car so i just cant see having an automatic in it

The 5 speed will add to the project , but can be done .

I have a cable type bell housing that i used in my 78 LUV with a 283 but i don't have a cable for it .It's a Monza bell and i think the cables are available still,then you make the clutch pedal end fit. It's and easy thing to do.
And yes you will have to cut a hole farther back to install the shifter,the rest is the same as you would do with the auto.
Using a T-5 with this swap would be a cool swap and no you don't have to modify the fire wall.

do you rhink that i should run a edelbrock dual plane manifold with a performer 500 or stick with the tbi. is there any way of not using the computer for this motor and if so what other parts need replacement

kind of depends on what your aiming for

you can find alot of 4.3's out of s-10's and blazers and probably someone who has done it before on some of the s-10 forum sites.

before alot of s-10 owners switch from a 4.3 to an LSx motor they will supercharge it and do alot of other mods. You might find someone selling the stuff on the s-10 sites.

I know someone in TX who keeps offering my a complete 4.3 w/ harness, cpu and transmission. I just dont have the cash nor the room to go after it at the moment.

Your on the right track with the manifold and carb, then all you have to do is get a dist. and you will have a computer free runner.
You can try to find a used HEI dist. or as i would go to the after market and get one like a MSD,DUII,or Mallory then you would have a permanent set up.
If you are going to get inside the motor use 350 flat top pistons as this will make the motor a stout street performer.

I already have the motor. like i said its bored .30 over with 350 flat top pistons and stock injection. I also have a 700r4 but i want to run a five speed out of an s10

Well then the simple way (cheaper) is to run the t-body injection and is very simple to hook up other than you need a fuel pump and a return line and it is done .Like i said i have a bellhousing if you get a T-5 trans.

I know it may sound like a pain to run the injection but the start up and drive ability all year long would be more than worth the trouble.

Also if you use a S-10 rear with 3.42-3.73 gears you would get excellent fuel milage as well as a stout performer.

how will the 4.3 computer handle the t-5 trans and if you have parts for sale to help me with this swap let me know prices and shipping to 48067. thank you all for the help. I tried to get help from s10 forums but those guys are just complete ideots.

The reason you will get help here is the fact many of us have done the conversions and have a ton of success.
