Ok.. i think i understood u.. u are looking for a 3.4 to put in with your 700r4 instead of having to replace everything for a 350? If thats it..look on ebay.. they are EVERYWHERE... Btw.. after that learn how to talk so we can understand it

Ovrclck is correct, just get a trany. The fun part begins though re-wiring the harness, I think painless wiring has a kit though.

how hard is it to put the new harness in though...cuz i mite be able to have my choice of either a 3.4 or a TPI 350 cuz i am prolly gonna get it installed by the mechanic's program that i am attending in college........Free Labor=More money for parts=quite possibly a TPI 350
i know that the motor mounts, springs, harness, tranny, radiator, dual fans will need to be changed if i put in a 350, but what little odds n ends need to be changed? nothing?
even if my college dont do it, i'll be a mechanic in 2 years, so my parents will have a hard time trying to stop me hehehe

BEFORE YOU JUMP INTO THAT PROJECT, check you state emission laws.
That's why I went to the 3.4 swap.
No emission hurdles to jump!
NO REPLACEMENT FOR DISPLACEMENT!
And 90% of your current V-6 parts swap over, no problem. That equaled lower intial costs, too.
AND it is a very sweet running ride!
This car runs like a Freight Train! Now that the Caboose (tranny LOL) works again!!

2nd, you might get paid for an internship some places pay you and others cut a check to the school, although the school will not admit it "Black market labor"

Hmm 1st its probably too big of a pain to go from a 350 to a 3.4 and you would need a transmition so why not compromise and go for a 4.3? But then if you have tpi instead of tbi you will still run into problems with wires. But if you had tbi its an almost direct swap all you would need electronicly is a 4.3 computer or a special prom.

The wiring isn't that hard to convert for a TPI setup.
EDIT: Took out all the useless information.

He reminds me of the little whining kid that always wants to hang out with cool people... yet, nobody wants the whiner around.
The rewiring shouldn't be hell; I don't believe you have to go into the dashboard at all. I had to pull my engine wiring harness when I totalled the car, in order for the weldor to get in there and do his job. The entire engine harness goes through the passenger fender. Inside the pass. fender, there's a pass-thru connector that goes under the dash. After that, the wires go right into the computer- no further.
The harness on the driver's side is, I believe, only for "common" circuits, like headlights, cruise control, blinkers, fuel pump, etc. I don't think you have to touch it at all.
So from a junkyard car, you'd yank the main engine wiring harness and the computer, and you should be all set for the 350 swap. One hint: Take a polaroid (or some kind of camera) with you, and photograph how the wiring harness is attached to the engine/engine compartment. Take pictures of how the wires are routed around the engine, too. I didn't do that; and some parts of my wiring harness aren't following the factory routing. In fact, some look plain "wrong" to me.. I wish I had some pics of how my car's wiring was originally run.

How much of a difference is there between a 3.4 and the 3.1 Is thee a big difference in power??
I have been toying with the idea of a biger engine, but I like fuel economy of my 3.1. Any sugestions??
Thak you!

I may get jumped on but, here is my take.
The cam of the 2.8 is the same as the cam for the 3.1
So are the heads.
This answer I saw in Chiltons for the cam specs.
The heads are the same, anyway ya look at it.
I assume the bore and stroke is larger on the 2.8 BLOCK to equal the 3.1 size.
The 3.4 has different cam (designed by Crane), crank, bore stroke, heads (better springs and retainers for the higher horsepower).
The 3.4 block has more meat in it.
YOU cannot bore out a 3.1 to equal a 3.4. Even GM says so. Check the latest GM performance Parts book for that detailed answer.
You need start with the meatier block to get the 3.4. IF ya want a 3.4, I can arrange one for ya from LA. I can get 3.4 blocks from $800 (and more or less depending on engine milage).
Convert to a V-8? Check you local emission laws FIRST! The V-6 has a specific VIN code saying it's a V-6. That will bite ya if your emission laws are very strict. They are in CA. I was given a V-8, my VIN says V-6, I did my 3.4 swap. No emission problems at all! they couldn't tell i swapped, I didn't offer!!

Ked85,
Did your research??
Now that performance book you speak off is it avaliable from any GM dealer? If so i will stop my local dealer and pick one up this weekend. it sounds like a good read!
From what you said it sounds like the 3.4 can be bored biger. Is this correct? If so that just might make it worth it for to get a hold of a block and build it up!!

sorry iroc5.7tpi you kinda started things yourself by saying that the V6 boys suck
we each have our own cars for our own taste
I kinda like the V6 myself
dont get that inflated ego.
still just keep it calm and quit saying we suck
hey a camaro is a camaro why not lend us a hand when all is going on is the bettering of the cars rather then fighting us and saying we suck

Actually, I did the reading from the book.
I have to admit, I'd rather believe the opinion of an engineer from GM, than many others. When ya see the optional blocks available from GM for a V-6 60*, you'll notice what size they say those blocks can go to. Before I try to sink money into a project I'd rather get alot of common sense answers (why spend the $$ and effort on a losing deal?).
When I showed my V-6 swap to a 1991 Mustang LX owner & took him for a ride and told him the price of my engine, as is, no rebuild, etc, necessary, he was floored! My conversion/swap can really work out in your favor, if ya keep alot of personal desires/varibles in mind doing your research.
I wasn't trying to build the fastest V-6 here on the board. Just a great running car, that can do alot and give ya plenty of smiles in return for the effort. AND PASS SMOG WITHOUT ANY TROUBLES! I feel I suceeeded on many of those issues, & that's why I suggest this option of the 3.4 swap.
