Hey everyone...

A friend of my cousins is selling a LT1 out of a "96 Corvette".
Did the 96 have aluminum or iron heads?
It has everything, Radiator/dual fans, accessories, wireharness, computer, and 40l6e auto tranny.
Anyone have any info/specs on this particular engine.
I am considering buying it from him.

Aluminum heads. Same ones found on the f-body LT1's.

JR92z28

That's what I thought, but my cousin looked at it and said they were iron heads.

I'll check it out when I go and look at them.
He said the intake was powder coated black.
Anything particular I should look when I go check out this engine?

ME Leigh

I bet its out of a vette! Some how when people are selling engines they are always out of a vette. I bet is a 4.3l baby LT1 out of a caprice. The only iron LT1 heads IIRC are out of Caprices.

Good Luck

JR92z28

pffft...

I just read a mag that had a 94 Z28 LT1 with iron heads, so I would have to say that not all Camaros and Corvettes had iron heads. I know this person very well and he wouldn't advertise it as out of a Vette if it was out of a Caprice.
Your post really doesn't help on this thread.

ME Leigh

Ok dude, whatever ***. I'm just trying to help from getting screwed. Vettes never came with cast iron LT1 heads!! The only ones with iron heads are Impalas and Caprices.

12554290...94-96...350..........Gen.II, "LT1", cast iron version, used on "9C1" Police package, Impala SS, Cadillac Fleetwood, Buick Roadmaster reverse flow cooling

10125320...94-96...350..........Gen.II LT1, cast iron version, used on "9C1" Police package, Impala SS, Cadillac Fleetwood, Buick Roadmaster reverse flow cooling

14088526...........350..........Gen.II, LT1, aluminum
12551561...96......350..........Gen.II, "LT1", aluminum
10207643...94-96...350..........Gen.II LT1, aluminum, reverse flow cooling, 175/68cc port volumes

10205245...93......350..........Gen.II LT1, aluminum, reverse flow cooling, 175/68cc port volumes

10128374...92-up...350..........Gen.II LT1, 53cc, angle plug, aluminum, reverse flow cooling, 175/68cc ports

But i guess you don't want my help, you already know everything!

JR92z28

My cousin said they had iron heads, but who knows.
I have to go and look at it myself. It may very well have aluminum heads. I also read there was a 93 or 94 Z28 with and iron headed LT1.

Thanks for info though...

JR92z28

Oh and what are these numbers at the begining?
12551561...96......350..........Gen.II, "LT1", aluminum

Can I find that number stamped on the block or heads to really identify the motor?

JR92z28

hmm... well can't I look at the Computer and check the ecm or chip number and determine what it is from that way?

Thanks again.

Red Devil

And you expect him to help now?

Guess what, this post won't help either, but you may find something if you...

JR92z28

Well at that time that post didn't help me any.
I just say it like I see it.

He can help if he wants, I don't expect him too.
It's up to him, don't come and instigate...

Red Devil

Yes mommy, but if you would remove your cranium from your rectum, you may realize I gave you your answer.

JR92z28

search I did and still reading, I was just looking for other answers like how to determine what it really is.

Go look at some pr0n or something, you're not helping.

Red Devil

Yea, good one. P0rn, internet... yea, original. I'm not the dolt that doesn't know what casting numbers are, nor, apparently, the one that doesn't know how to search well. Oh yes, if you are still reading the results of your search, why did you post this? Too lazy? You've now attacked two people trying to help you. Great way of making sure no one else wants to. Dolt.

JR92z28

Uh, I haven't attacked anyone but maybe you.
If you call these small words attack, then you obviously spend way too much time on your computer...
I asked for help that's it. If no one replys then I'll move on.
I certainly didn't want to start a flame thread.
If I'm too lazy to search, it's not your problem is it?

ME Leigh

The head casting numbers are under the valve covers. The block casting numbers are on the top rear near the bellhousing. It should be easy to tell if the heads are cast or aluminum. If they are painted or rusty then they are cast. If they are a nice metal color then they are aluminum.

FYI all my engines are from Vettes even my 305's, wanna buy one?

JR92z28

Thanks for the info, I'll look in those areas when I go check out the motor.


LOL, no thanks, I need to purchase one out of a vette locally!
Hopefully it's out of at least a Z28.

JR92z28

Blah, if it does have iron heads, hopefully it's not the 4.3l!!!
Hopefully it's out of an Impala or cop car!

trans87

This is very easy. Go look at the car and bring a magnet. See if the magnet sticks to the head or not. If it does it's iron, if not you got yourself an aluminum head.

scottland

yep, it's that easy.

JR92z28

I know the difference between them, it's just someone saying they are alluminum and another person saying they're iron.
My dad went and looked at it and said they were iron, so I believe him for sure, because he know his motors.
So now I have to go check it out to determine exactly what it came out of.

It had to come out of a B-body. Every year LT1 vette and f-bod had aluminum heads.

JR92z28

I have now figured that part out now.


I just hope it's not the 4.3l now.
Would it be worth it if it is a 4.3l?

ShiftyCapone

iTrader: (7)

Nope.

JR92z28

That's what I was afraid of...

JR92z28

Ok one more question, these two listed at the top of the list show iron heads. The Impala or the cop car never came with 4.3l did they? If this is true, hopefully it's out of an impala or cop car.


Thanks,

DURTYBIRD

Yes, some cop cars were equipped with the 4.3l...they also look identical os be careful!

Look on the rear deck surface of the drivers side head (where the head meets the block). I think the LT1s still have a casting of "350" on them facing up.

Only other way to know for sure is to pull the casting # and do a search over on mortec.com

JR92z28

So if it says 350 on it, what would it come out of w/ iron heads maybe different year?
I know a 305 is a 5.0 and a 256 is the 4.3, that would make the 350 a 5.7?
My dad looked at it and said it was stamped 350 near one of the heads, if this is so would that make it a definate 350 5.7(?) ?
I'd probably have to give the guy an answer on the spot, without being able to get online and search the vins.

Thanks,

ME Leigh

Yes a 5.7l 350cid, out of a Caprice. They are not bad motors and the heads actually flow a little more then the aluminum. But the cams suck and probably some other things.l

I told you magically everybody has a vette engine when their trying to sell an engine!!!

Yeah obviously!!

DURTYBIRD

IF it says 350 on it, that should make it a 5.7l out of a Caprice/Roadmaster/Fleetwood. Now that I re-read this, that stamping may say "5.7" instead.

Only if it's behind the driver's side head on the block casting facing up.

HTH!

JR92z28

LOL, I guess they just want money and would lie for it!!


So I know it's definately stamped 350, and you said the heads flow almost as good as the aluminum. I'm assuming they are close chamber heads? So if all this adds up I guess the motor is worth my time then? Just swap out the cam with maybe an LT4 and port & polish the heads and some 1.6 rr's?


Thanks again!

JR92z28

Thanks, I'll keep this in mind.

DURTYBIRD

Usually it's not an intentional lie. I think it's probably more 'misinformation' taken as fact.

Actually better than aluminum. I've heard that the iron LT1 heads are a similar design to the vortecs.
- If you are thinking hotcam, don't forget the valve springs!

ME Leigh

Let us know what you get and how it comes out. I'm very interested now!

Drakar

Just to add a few pieces of info.

The following got LT1's IRON Head version and nothing else

94-96 Roadmaster
94-96 Custom Cruiser
94-96 Impala's

The following got LT1's or Baby LT1's

94-96 Caprices


The above are all IRON

Vettes and F-body's all had aluminum heads if they are iron in either of these cars they are not stock.

Sorry if this was posted earlier or people already stated, figured I would put it into 1 quick reply.

fisherbody86

This is slightly off topic, but has anybody put the 4.3 LT1 crank and rods in a 5.7 LT1 and made a 302 LT1? That would be awsome, and a whole lot cheper that making a GEN 1 302. Those GEN 1 3.00" stroke cranks are REALLY expensive.

I had breifly thought about this, and would still like a GEN 2 302.

ME Leigh

Yes one of the magazines did a write up of one a while back. Some automotive school or something was doing for there 4th gen drag car. I can't remember what mag though, i'd have to go through my 4' high stack.

There is the Sema show 302, LS1 version.

very nice

third_genbowtie

this is kinda off topic...i bought a 96lt came out of a C4vette. its complete and includes harness comp ect... and he gave me the cats so cats are included also... i did a search and it seems OBDll pcm's are a pain in the azz to get tuned. now this is the question: what kind of serious problems (electrical related) will i encounter doing this swap also whats the big deal when it comes to OBDll vs OBDl whats the big difference ...this is getting me worried

thanks

It didn't occur to you that maybe you should start a new thread instead of digging one up that's 5 years old and off topic?

To sort-of answer your question, there are enough people running LT1s, that you shouldn't have any problem finding out how to use the OBD II comuter. I'm not specifically familiar with LT1's OBD II system, but my guess is that it's very similar to the GEN 3 stuff in that rather than burn chips, you use an editing software to modify the computer. This is something that's very common, and there are plenty of talented tuners out there. Whether or not you decide to tackle it yourself would be another issue, but there should be plenty of help available should you choose that route as well.

third_genbowtie

yeah your right about digging old post up. but it threw me in here when trying to find more info on the web. so i didnt realy look at the date. ok so pretty much after doing the swap i will be keeping the cats from the lt because it will throw a code due to o2 sensors on the cats...getting it tuned from a professional.

iTrader: (3)

You can get those 02's deleted and run simulators if you want to.

Klortho

OBDII ran 4 O2 sensors, starting in '96. You can run a 95 model PCM and only have the two O2 sensors before the cats, but not for sure if that would be legal in Kalifornia or not.

ty_rich

Some people are so funny, two posts before this you say you can tell the difference between iron/aluminum, but your gonna bring your dad...so you nor sure or what and fyi....vettes, camaros only came with aluminum heads, and dont ask questions and bad mouth the people that are giving you advice

Klortho

Dude, look at the date of the post you just replied to.....it's over 5 years old.
