I know it has been asked a thousand times before, but i have never payed any attention.

What is needed for a V6 to small black swap.

 

transmission, motor mounts, ECM & wiring, and a whole lot else. Kind of depends on what year engine and car you're dealing with.

 

I literally just did the swap from a 3.1 to a 350 tbi. It involves a lot of time and money. If you’re going from a 3.1 or 2.8 to a stock 305 or 350 it will be a whole lot easier. parts that I needed were trans, motor, motor mounts, trans crossmember, wiring harness, computer, distributer,plug wires,spark plugs,headers, y pipe, 350 injectors, serpentine brackets and hoses for ac, radiator, radiator hoses, cross member brake line (you can bend the v6 one) and a ton of bolts.
Try and find the same year wiring harness. I bought an 89 harness and put it into my 92 and had to splice and move a lot of stuff around. I put a 355 motor in and that requires a lot more parts. such as computer reprogramming bigger injectors, bigger stall a lot of sensors etc.
If you have a parts car that was a 305 or 350 you will run into fewer problems and save from buying little parts that add up a lot.
It’s not the easiest swap but is fairly strait forward and you feel really good after its all said and done.

 

do i just have to get v8 motor mounts?

The motor going in is carburated with a TH350 and i have the trans adaptor and the crossmember from a v8

 

You'll need a bigger radiator too.

 

all i want to know is if i can use the stock motor pads and mounts from a v8.

 

this should be a faq by now

 

yes you can use the motor mounts from either a 350 or 305 with no problem

 

you have to move them up or down (forgot already lol)1 hole so the motor is properly aligned however

 

A factory V8 donor car.

 

the later year V-6 radiators will work fine, as long as the return hose is on th bottom passenger side,,,I had to change mine.
PM me if you have any specific problems...I would be glad to help (as much as I can, and I'm pretty much limted to the old school stuff, carb,,,goodbye computer kinds of stuff)

 

foreword and the holes are already drilled..but the are a b1tch to change.

 

How many questions did you have while you were doing your swap? I asked a lot.... I was told this was a tech board for engine swaps. why would I come here if I,m made to feel ike ive asked a stupid question...somebody sent me this...kinda set me back some

 

When i said it should be a faq i was serious. With the amount of people who ask this question it should be.
I know when i became a member i asked the same question

 

Ok ,I see where you are coming from now..sorry My bad..
I'm off of work due to an accident right now that is going to put me on disabillity. Maybe I can work up a paper on the swap...Im no technition, but I have done a couple of swaps v-6 to v-8. I could run it past the board GODS,Never know, Might end up in the faqs page.

 

Are the later v6 radiators the same as the v8 ones?

 

I was told to replace my radiator (pffft) but I have a 91, I was told the v8 radiators are 1" 1/4 wide, I measured mine and what do ya know, 1" & 1/4. Just run it with the radiator, but I suggest getting new tanks.

 

Yep...they seem to be... 89's are not useable the feed and return lines are reversed....

 

From what I have been told...

If your V6 had AC then it had the Same Radiator as the V8, If not then the hoses are on the opposite Sides.

I have also read that the 4 Cyl Radiators are the same as the ones for the V8.

But I would double check on the part numbers to be sure.

 

my v6 had AC, and it would not work with my v8

 

hey man just wondering are you actually doing that FAQ thing? cause im about to be building a 383 Stroker and i was wondering if its the same thing as puttin in a 350...cause its the same block cept for the bore and all the insides.......but i currently have a V6 auto and my future plans are to go for a 383 standard...... now......alot of people say " just buy a new car" well.....3rd gens are becoming rarer and rarer from what ive seen......so no, im keeping it......im only 17 so i have alot of time.....the car is in awsome condition and i really want to do the swap......so man if you make that faq you wanna email me??
bionicle911@hotmail.com or if you got msn we could talk about it.......cause you said youve done this before........

BTW if anyone knows the parts for the auto to standard swap please correct me if im wrong

-TRANNY
-CLUTCH
-BELLHOUSING
-CROSSMEMBER
-DRIVESHAFT
-ALL CLUTCH LINKAGES
-BRAKETS that hold pedal
-PEDALS
-REAR END
-CONSOLE shifter stuff (plate, boot, **** all that)
-FLYWHEEL

thats all i can think of

:lala:

 

Rear End is Optional (Depends on if your looking for MPG or Take Off...)

Computer is Different for Manual than Auto, Not sure if its just a chip swap or a full blown box swap.

 

There's a stickie at the top of the forum now.

 

Someone mentioned doing an engine swap and having to splice wiring harnesses... I'm just starting a V6 to 305 swap, and I have a complete donour car... I know little... no... NOTHING about wiring. Thing is, my car is 88 with power windows, mirrors, locks, etc. My donor is an 84 with all manual options. My question is this: The wiring harness comes out of the firewall on the drivers side, and part of the harness runs to the passenger side, and back into the car on the passenger side... What is this wiring for? Is this for all the interior items and power options? If so I guess I'll have to keep this and change the rest of the harness....

 

Take a look at the stickie https://www.thirdgen.org/techbb2/sho...24#post1739624 . I updated the harness part to better address your issue.

It doesn't have all the details, but covering all the specifics in a few sentences would be impossible.

The interior items are not affected by the engine swap (generally speaking).

 

That pic made me mad

tell that guy that sent you that : try doing a search for V6 to v8 swap. a-hole.

That sticky is a very good idea. But more info is needed. Like the TH350 thing, etc. To be complete it will be more of a 'book' than a sticky.

The specific question I have is:

I just got 3" exhuast from the Y-pipe back before my V6 blew.. again.. Will a V8 y-pipe join at the same point?. My V6 y-pipe had the catalytic converter replaced with a straight pipe.

Being as a salvaged complete V8 carbed f-body's go for $450 to $1000 canadian, this is the only econimical way to go. I can't see it costing more than $1500 together.

Maybe a better question: Is a V6 intermediate pipe the same as a V8?

 

yea as amatter of fact, he got run off the board.
Hey I just bought some hooker lontube supercomps.....I have the full exhaust of the 327...custom y pipe into 3" pipe run back to turbo dual out in the stock position...no cat sounds real bad
3oo american you pay shipping

 

You will probably have to modify the connection at the V8 cat, but the pipe is routed the same and the components connect roughly in the same place.

 

dependinon the headers you plan on running.....my y pipe wouldnt work......but, ya just never know on these swaps till ya try,,

 

For now I just want to get on the road, cheap as possible, I'm driving a four door Dodge right now...

Headers will have to wait.

Looks like there may be some (inexpesive) exhuast work involved. Bigger issue for me since I only go to the city the cars located in every second week-end.

I'm no stranger to wiring harness/engine/fueltank/rear-end swaps so I estimate 4 three day weekends just might be enough. As long as I don't end up coverting to standard, which is tempting.. If I had a cup holder...

DITTO

 

Guess I didnt mention the shorty headers..but the are summit brand 1 1/2

Make me an offer I cant refuse..I CANT USE THEM ANYMORE.. I drove the setup for about a year and all the welds were done by a pro...no scam just trying to help a fellow thirdgener.. I could post a pic when I get it all down.

 

Darn that has to add a few HP..

 

You know one other unsearchable thing. 60* engine.

After prowling the V6 board, somehow I got it in my head that I needed a 60* V8. Imagine the looks I got telling people I'm looking for a 60* V8. Cadillacs had them...

I'm an idiot.

That cupholder is a bit inconvienant for me. In front of my radio, in my ashtray.
