Hi I own a 1992 pontiac firebird v6 auto, the head gasket blew and I got the car cheap, Im in process of swap a 350 carb into this car, and the more I read the more im confuse, about the tranny, wiring, engine mouting, fuse pump, computer, I just dont know where to start, can some one break it down for me, what I need complete to swap a card 350 into my v6 fuse injector automatic please, btw should I buy a complete stock 350 engine to begin with or this guy selling me a 350 carb with .60 bore over, cam, engine is build for race, something like that, and he say the car is 13 or 12 something compression, even 92 octain barely good for the car, only race gas, I want somthing that depenable, and I can drive every day. thanks you for reading and please help me out.

 

Where are you located? You can buy my '86 Trans Am that has a small block 400 in it and just use it for parts if you want. It's even got rear disc brakes that you can swap over!

But to actually answer your question, you are gonna have to pull the tank to remove the in-tank pump and make yourself a pick-up tube then use some sort of aftermarket in-line pump.

Pull out your ECM(computer) and follow the wiring from it around the engine disconnecting as you go. I actually just did all this on my 86 Trans Am. The main issue I had was that you have to basically drop out the entire rear suspension just to pull the fuel tank and you will have to either wire the electric fan up to a switch or so it'll come on when you turn on the key.

As for that 350 the guy is going to sell you, .060 over is quite abit and some people seem to have cooling issues with engines bored that big as it makes the cylinder walls rather thing. Another thing as you pointed out yourself is the 12:1 - 13:1 compression. That is NOT pump gas friendly. I would stay away from that if you plan on keeping that thing a street car.

Good luck and happy motoring!

 

Im live in Jackson MS, That what I though too, I rather buy a 350 from a complete car and tranny that is running, and keep it stock for now, and will mod later, if any one have more opinion please post here, Thanks alot.

 

If its a relatively stock engine you could probably use a bypass regulator and use the in tank pump. Save a little time.

 

so I need a 700r4 v8 tranny ?

 

You need a transmission with a Chevy V8 bellhousing pattern, yes.

 

can you just change the bellhousing ?

 

Sticky much???

Carbed motors aren't bad at all relax and take it slow. Me and my buddy have dropped quite a few 350s into many cars for demo debrys. Carbs pretty easy less wiring etc, tpi threw me through a loop for awhile. goodluck check out the sticky it should tell you everything you need to know

 

I found a van duravan 2500 from 84-85 , it had every thing to swap, but 305 is kinda push me back, and one more thing that I just dont want get my hand on it because the owner die !! he too old and die so his sone sell his van to the yunk yard that kinda scare me, but I still searching for a complete 350 engine and tranny.

 

got to love public schools....

 

Thats not very nice 355. Maybe he's dyslexic.....Or drunk.....Very very drunk.

 

yes I am drunk now, im wait for my friend come over, so we can pull the engine out, I call all the yunk yard around here, asking for 350 with tranny, but none carry, but Im still search for it.

 

Have you tried craigslist? I see 350's advertised all the time around my area.

 

stop with the panic already this is the easiest swap known to man first ask yourself if you want od or not if not turbo 350 if so 700r4 use mounts from any v8 car such as 78 malibu el dog or caprice you will use frt mounting holes in your frame,same tranny mount same driveshaft and the best way to wire this thing is simply cut all emission wires only keep coil wire starter and alt wires gotta go drive the bus now ,im a automechanics instructor but ill be back and well walk you thru this piece of cake man trust me ---------------------------------bigzeke355cid92bird

 

thanks I will be back here when I have the engine and tranny ready.

 

Hi we plan to pick up the motor tomorow, and tear it down, send it to the machine shop and fresh rebuild, btw where I can get V8 front springs and sway bar ? what year do I need to get, i got 92 firebird, i need to get 92 v8 front spring and sway bar for that year ? and where I can get subframe connector because I have a t-top. thanks

 

spohn.net has everything u need.....

 

The engine will be tear apart for replace piston and cam, on the time it tear apart, what is good bolt kit that I can use, since I dont like reuse old bolt. thanks

 

I pick up the engine today, and here what the owner told me, a 350 with TWR pop-up piston, bored 60 over, 327 camel hump heads, wicand intake, crome valve cover and oils pan, the car is 13.1 compession, we going to tear apart this saturday and change piston and cam for street and strip, all for $500. can any one tell me what year and where this engine coming from, I want to know what oil filter im need to run on this engine and plug and plug wire.

engine number GM 3970010

 

That is a 2-bolt or 4-bolt SBC block from 1968-1980. It's probably a 327 or 350.

13:1? Dang.

 

its 350, we going to tear it down to see its 4bolt or not.

 

any one here know where I can get a engine mount and tranny mount kit for the v8, since Im think I need replace it any way. Or should I get those from gm ?

 

Get aftermarket poly mounts - poly inserts for the engine mounts, poly mount for the transmission.

 

Do you know the site ?

We strip the engine mount bolt ( passenser side ), we try every thing, heat it up, wb 40, try to fix the 15inch socket, what other methor to take out strip bolt ? thanks

 

dude, you need to find a " pull a-part junk yard" near you and raid some third gen. or you need to find a local beater sitting in someones back yard and strip that thing. your best bet would be to find a v8 car and use your v6 for parts!

 

by the way, stay away from the engine with high compression. trust me i'm speaking from experience, you'll have all types of rattles, pinging, and spark knocking. unless you can afford 7 bucks or more for a gallon of gas!

 

a buddy of mine going to tray me his block he been build it for over 4 month now, he got the block out off 1992 cadillac 350, and use my camel hump head, when it done it will be 10.1 compression, or 9 somthing compression, that good enough for street.

btw wat oil filter do I need to use, I look up wix filter, and one for 51060 and other is 51069, but both use 350 block, what should I use ?

if I want to get fuel filter, should I got with the engine year or my car year 1992 pontiac firebird v6 or should I say v8 ? thanks

 

not sure about the caddy 350. the double hump heads are great heads if you have the high horse heads. some double humps were not that powerful.

like i said before,be careful with the high compression! it may bite you on the butt. i have an old set of heads with 10.5 to 1 and i hate it. 93 octaine is to weak and the racing fuel cost too much. i'm in the process of saving the money for some different heads now.

the oil filter, i would get the one for the car it come out of.

not sure about the fuel filter. i have an inline filter under my hood so its easy to change plus they only cost about 5 bucks.

 

When he bring the block over, I will take some pix off it, and engine code, will you tell me what year the block is coming from ? and tell me what oils filter do I need ? thanks

 

take a look at this website. maybe it will help you with your casting numbers
