Hey a buddy of mine just bought a 1990 Camaro RS with a fuel injected 350 in it, i was wondering if anyone has ever pulled the engine on one of these and replaced with a LS1/LS6 long block?? If so how hard and what is needed to convert all accesorys over to gen 3 setup??
Im not sure if the 350 that is in there now is a old style LS1 or something??

The 3rd gen camaro has the Gen 1 engine. The LS1 is a gen 3.

Lots of people have swapped in LS1's but IMO it's not worth it. MUCH cheaper to build a gen 1 383

just to know what is probley in there do u guys think there is a LT1 in his camaro??
also would it be easier to just pimp out an LT1 instead of putting a gen 3 LS1 in there??

Who put the 350 in it? From what I remember the RS had the 305 w/tbi injection.

Uless someone swapped a Lt1 in its not an Lt1. My guess as to what is in the car is either an L98 or L05. Have you saw the engine if so I can probably help you identify it.

We need pics to look at for the right answer. It originally came with a 305 tbi eigth digit in the vin is an E right? That E stands for one of the worst V8s ever put in a F-body-I've owned one I can say that. Help us help you with pics to identify. Nothing is interchangeable with a 3rd gen's motor and a gen III motor.

I have a LT1 in my 3rd gen vert and if i had to do it again i would still do the LT1 over the LS1 just because of cost issuse it is much cheaper to do an LT verses LS motor. I put a hotcam kit with 1.6 roller rockers and stiffer sprigs with longtube headers 3" true duals and put down 320rwhp and 348rwtq.

ok you guys are probley right that it is a 305 not a 350, the guy he bought it from told me and him that the car had a engine swap done to it and that there is a 350 in it, but i still think that it is a 305 since it has tbi injection, unless they made tbi injection for a 350??
so i bet the guy just told us that so that my friend would buy it, even though he got it for $400 bucks lol
Ill let him knoiw the bad news in the morning and maybe we'll grab an LT1 and see how hard it would be to do a swap, and also ill get pics just in case on some miracleous reason that it could be a 350 lol.

the only way to know its a 350 and not a 305 without tearing it apart and measuring it is the block number. its on the block behind the driver side head near the firewall it will be nearly impossible to see it in the car but if u can get that number and check it at http://www.mortec.com/ you can know what it really is. and i dont see a point in swapping in a LT1 into the thirdgens i mean its really just a fancy reverse cooled sbc. if you are going to swap anything besides a gen 1 sbc in it u should go LSX...not that hard and the power is worth it. a stock ls1 into a third gen will be faster then a stock 4th gen ls1 camaro because the third gens are lighter....check this out http://www.thirdgen.org/techboard/lt...want-swap.html

You can also find some good pics and posts for the swap under my same username as here over on thirdgen.org

Just look on the back of the block where the trans meets the block on the driver side. There will be either 5.0 or 5.7 stamped right there. I can pretty much guarantee that it is a 305 because that is what the rs came with back then with tbi.

An lt1 swap is easier but an ls1 swap will be a faster car. The compressor for the a/c is on th bottom for an ls1 so you would have to notch the k-member to keep the a/c.

You can do either swap depending on how much you want to spend on this. Either way ditch that TBI crap. You are very limited in anything with that tbi.

You have to make damn sure that you love your car enough to do a LSx swap. It is not cheaper in the long run, it is VERY time consuming, and not everything will work or fit in without serious modification. Among these are interior controls for HVAC, A/C itself, guage cluster, upgrade brakes and suspension (fourthgen LT1 brakes were barely enough stopping power, let alone 3rd gen brakes for LS1 power). The body will need to be reinforced with subframes, 3rd gen power twisted the chassis (stress cracks on the roof at the top corners where b-pillar meets the roof).

I don't think Sheldon's example is a good reason why to do a swap, it's good for information on how to do a swap, and it seems like you are still in the justification stage. If you want a LSx car, buy one outright. He stated he wanted a LS1 car, but had no cash, now he's invested god knows how much time and $$$ and probably could have a 427 block in a 4th gen by now...

If you feel like a hobby or a project or like the look of a 3rd gen but want power, there are other ways to go about it and gen 1 engines are dirt cheap to make lots of power. If you want to toss in fuel efficiency, go FI as well (forced induction). You'll save a lot of cash in the long run over a run of the mill LSx swap which is now getting pretty common.

Everyone is right it is a lot of money and time to put an LS motor in a thirdgen. The biggest thing is the more money you have the easier and quicker it can be done because you can solve some problems by buying swap parts like a new k member. The guages are a problem but can be fixed. If you trying to do it on the cheap you're going to want to make it carbed it will save the time and money of swapping fuel lines and tank and alot of wiring.

This post went wrong in so many ways.

1. Good god do a fricking search. Hell I've posted this link in every one of these 3rdgen threads.
http://www.team3rdgen.com/modules.php?name=3rdGenLS1
not to mention yet again TGO. Oh wait you didn't even post this in the right forum, conversions and hybrids, so I am asking a lot.
2. Wait now I understand the logic behind not doing a seach. You're one of those people that believe every, SBC is a 350, Every old school 350 is at least an Lt1 and every lt1/ls1 is the 'vette engine'
Skills required for ls1 swap > you
3. All the "OMGZ teh cost" posts in this thread.
Ok my ls1/t56 cost $2500 installed. $1000 of that was hawks headers.
So go ahead, tell me how you can get 340RWHP out of a 305TBI for $1500-$2500 which is what the RS the OP is talking about has?
4. All the "OMGZ teh time"
I DROVE the 3rd gen in the garage, and DROVE the 4thgen in also.
So including the time it took me to pull BOTH engines out of BOTH cars and install the LS1/T56 and drive it out of the garage was 10 weekend working days. That was the first time I did the swap. If I had to do it again I could cut it down to 6-7 days.
Just because you can't do something fast or cheap doesn't mean other's cant.

This thread is EPIC FAIL for some many reasons. But hey continue to post in it like the swap will happen!

lol wow... he is right though. and i believe these forums are a good and bad thing, people who should not even be allowed to own a hammer think that they can do engine swaps and build engines and it erks me bad. Alot on this post is over simplified and I believe that even changing his spark plugs might be a little too complicated for the OP, i just didnt want to come off as an *** so soon on this sight but since others aparently feel the same, well then i shall bite my tounge no longer.
