What can you chevelle gurus find wrong with this?

[1970ChevelleSS]

What do you guys think about this car?

[JChlupsa]

There was a Red 71 LS5 here that was listed for sale as well in the paper. Nice looking car though that you linked to. First time I have seen that decal on a air cleaner though but then I dont get out much

[drdave69]

That is the first time I have ever heard/seen a SS "400". The broadcast sheet also states that fact and matches the air cleaner decal.
Is that legit?

[Jeff H]

Yeah, I can't say I've seen an SS with the 400 designation before. It's not even a 400, it's a 402. Very interesting. Nice looking car too.

[1970ChevelleSS]

so is this car correct

[MagicRatt]

I have seen that before on other Chevelles. It had something to do with the way the option was marketed. Some repair manuals will show a 400 w/2bbl and 400 w/4bbl. The 2bbl.was a small block. The 4bbl. was a big block.

So does that mean it should have a small block 400, not a 402 big block?

[KENNY_PASCOE]

LS3 ON THE BUILDSHEET IS A BIG BLOCK... KP

[Jeff H]

So is it really a 402 big block even though they advertise it as a 400? I've never heard of a 400 big block, just the 396, 402, 427, 454.

[WILMASBOYL78]

Between 70-72 there was some overlap in the use of the 400 engine size designation, it could mean BB or SB depending upon the car. This definately is the 402 LS-3 version which was rated at 300hp in 71 and down to 240 in 72. After that, well you know the rest of the story... http://www.yenko.net/ubbthreads/images/graemlins/tongue.gif

Nice car! wilma

[Xplantdad]

Just to add my 2 cents...this same engine in a Chevy truck was listed as an 8/400 on the side engine id's...I know because that's where the engine in my former Nova came from...it's actually a 402.

[BBIGG BLOCK 396]

And the trucks with the 402 also had a emblem on the front fenders that said 400 not 402.Although in reality it was a 402 C.I. Big Block and not 400 C.I. was this having to do with Getting insurance on the cars back then or something.I know I have heard stories to that effect but nothing ever in writing from GM.I know that is why they cut the HP ratings back on the models that are being talked about was due to insurance at least I remember reading that in some form before.

<font color="blue">Admit it. GM hiccupped on the use of
the 400. They said, lets .030 the 396 &amp; match B.O.P.
then they made the S.B.400 &amp; "oh no" change the B.B.
to a 402 for less confusion. http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif </font>

The TURBO-Fire 400---Small block
The TURBO-Jet 400---Big block --The lower power 396/402 =TURBO JET 400

[Pantera]

I have a 72 Super Cheyenne pickup for sale that has a 402 emblem on the front fender. It does not say 400????

http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif

[SS427]

seems like if I recall the early 70's Impalas mounted the 400 emblems in one place if it were a small and in a different area if it was the 402. http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif

[Chevy454]

Pantera: I've *never* seen a 402 emblem on the side of a '67-'72 truck, should be "400" if it's big block, or "350" if it's small block. Grab a picture of it if ya can...

[Bill Pritchard]

Rick, I don't recall the 70 and up full size cars being available with the big block 400/402. I believe you either got the small block 400 or the 454.

I'll go one step further and say that I've never seen an OEM 402 emblem on the exterior of any Chevrolet vehicle - car or truck.

[Schonyenko2]

Bill, my next door neighbor had a nice 72 , or 73 impala with the 400 bb in it. It said 400 on the frt fender. My dad had a 72 caprice with a 400 small blk. It said 400 on the fender also, but I don't remember if there was a difference in placement. It was confusing. Suburbans in that time frame came with the 400 bb also Cronkleton has on setting in his yard.

[budnate]

Pantera your glasses are steamed... http://www.yenko.net/ubbthreads/images/graemlins/grin.gif...we have a original '72 Cheyenne born with a 400BB and it has the 400 emblems....

[Pantera]

All I have is this old pic of it. I have it stored not where I am today but will go get a closer pic of it.

(comerucal Adv) It is a BB(now a 350) Th400 PS PB Cheyenne Super Custom LWB 1/2t pickup if anyone is interested I want $2500 for it. Usual rust in rockers and DS door/floor. I Supsect that there is some original paint still on the truck.


(EDIT) See below I found a disk of pic of it that I thought were destroyed in a kitchen fire I had recentely. I see I was wrong also.

[Pantera]

DAMMM... I am getting old and you guys are right. It has been a couple of years since I looked at it. I could have swore that said 402 but I just foung some pic of it and it does say 400.

[Pantera]

Glove box Data sheet. Wish all cars had this somewhere as easy to read.

[DaveC68]

In 1970 for both Monte Carlos and Malibus the 402 was marketed and badged as 400 4bl.
Chevelle SS, same engine, marketed and badged as 396.

[Pantera]

I was aware of that.

But, after looking at over 1,000 cars at BJ and the Pavilions cruse night in the last week or so, I am just overwhelmed with emblems and such. It couldn't be because I am getting old? Could it? I just turned 60, Jan 7th.

Oh well.....!!! Perhaps I am getting a little old..!

[SS427]

Bill,
I will check my literature as I thought that was the topic of conversation amongst friends in high school. I used to impress them as I could always tell them if an Impala was a big block or small block without ever opening the hood. That was a LONG time ago so maybe I am thinking of something else. Or maybe it wass just the way the ground shook with the big block........ http://www.yenko.net/ubbthreads/images/graemlins/naughty.gif

[SS427]

I did just find this on line. Now all I have to do is find some photos of the real deal.

"The 1971 Impala received small changes in outward appearance.............Engines included the standard 250 ci 145 bhp I-6 as well as the optional engines: 350 ci 270 bhp V8, 400 ci 255 bhp V8, 402 ci 300 bhp V8 and the 454 ci 365 bhp V8."

"Design changes for 1972 were minimal............It should be noted when making performance comparisons between the 1972 and newer Impalas to the 1971 and older Impalas that there were new methods to determine horsepower ratings. The 1972 and newer cars were rated on net horsepower rather than gross horsepower, which resulted in lower numbers. However, the 365hp 454ci engine from 1971 delivered the same real world performance as the 270hp 454ci from 1972. Engines included the standard 250 ci 110 bhp I-6 as well as the optional engines: 350 ci 200 bhp V8, 400 ci 170 bhp V8 , 402 ci 210 bhp V8 and the 454 ci 270 bhp V8.

ummmmm, could I have my crow with a little extra BBQ sauce, please? And I hope no one finds pictures of a car or truck with 402 emblems, because I'm not hungry enough for a double helping.

[SS427]

Bill, no worries. I was elated to find the information as I am wrong WAY more often than I am right and it feels kinda good.......... http://www.yenko.net/ubbthreads/images/graemlins/tongue.gif However, I do not recall ever seeing 402 emblems but am pretty sure that the Impala "400" emblems were mounted in a different location depending on SB/BB.

[DaveC68]

Just came to mind...71 and 72 SS 396's did not put the engine designation on the fenders, just the SS emblems (maybe after that there wasn't much reason to refer to it as a 396 at the factory or on the paperwork/buildsheets? ) http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif

[SS427]

Dave,
If I understand your statement correctly you pretty close. The SS 350 Chevelles used only the SS emblems whereas the SS396 and SS454 cars used the numerals underneath the SS fender emblems.

[P.J.]

my 70 Gm sales hand book lists for Monte carlo 265 hp 400
LF6 at 72.00 Candian and 330 400 ls3 for 161.00.
The shevelle options page shows a 330 hp turbo fire v8 400 enjine 4 barrel LS3 ( requires m20 or m40) price 185.50

[DaJudge]

That's a very nice and correct big block Chevelle. It was at the Vargo show this past fall.

[BBIGG BLOCK 396]

If you find a 402 emblem on the side of the 70 model trucks I will help eat the darn thing.I have never heard of a 402 emblem nor have I ever seen one.Doesen't mean that they were not any but I will help eat one if found LOL.I will just put a little A1 Steak sauce on it and eat slowly!

[camarojoe]

Back to the original question... are we saying there is nothing unusual about his car and that every big block SS in 72 had a 400 decal on the air cleaner and 400 listed on the build sheet? http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif

[RPOL78]

I had a 1972 Heavy Chevy Chevelle that had the same decal on the air cleaner and it was a big block.

[1970ChevelleSS]

thanks rpo

[GaryH]

There was a 71 454 SS at the dealership I worked at. I don't recall that type of decal either. This one was a flapper hood car though. Maybe the air cleaner lid was to small for that monster. I know they used that same type decal on the 71 Vette LS-6 cars. That's a gorgeous car! I'll bet it goes with "buy it now" in the next day or so.

[ohhawk]

Car looks correct to me. I have a picture of a '71 400 LS3 engine in front of me....shows the same decal that is on this car's engine. This source goes on to say in this piece that RPO LS3, Turbo Jet 400, a big block that debuted in 1970 as a non SS Chevelle option. Actually displacing the 402, the LS3 was basically a 396 with an enlarged bore and confusing name.

On a separate note.....the '71 and '72 Chevelle SS did not receive external badging unless it had the 454, otherwise, just SS. Also, the LS3 could be ordered on the '71 Chevelle even without the Z15 package. By the way, the Heavy Chevy could be equipped with any V-8 from the 307 to the LS3...the LS5/454 was not available on this model.

Rising tide lifts all boats and I think the '71 Chevelle SS's will appreciate nicely especially the 454's.
