LS6 1970 Chevelle info needed ?

[hemi24]

I was looking around my area and I came across 1970 LS6 Chevelle in good shape for sale anyone know a good website that I can check the vin to prove to me it's for real and on the car what do I need to look for to also prove it's for real I know how to do all this on mopars but on Chevy not so much.

Here's a couple - the first one has good info....

Just remember it ain't no Mopar....The VIN on these will tell you nothing about the engine. You need paperwork, the POP and to really check all the numbers on the drivetrain. Easy cars to fake.

they can be faked so easily , there is no engine code in the vin , an aquaintence subsidised his living buying clean chevelle bodys & making them all into Rare LS6s
He tried the same thing with a 440 +6 71 chall & had major issues trying to pass that off as a real car , it was spectacular when done just not a real 6 pack R/T

I had one a ways back. I guess check the engine vin and date and make sure you check engine casting numbers. I know of someone that ground the casting date down and re did it with weld to get the correct date and then painted over the weld bead. Of course any pictures or history from it's past will help. Previous owners etc.  In my case the previous owner was contacted and learned the engine was incorrect.
I paid 3,800.00 for that 4 spd car back in the 80's.

I agree engine code is not in the VIN. Build sheet to the car is the only fool proof way to know if it is a LS-6 car or even an SS for that matter. If the build sheet exists. Build sheet to my car was found above the gas tank. A lot of cloned SS Chevelles out there. Make sure it is a SS not a Malibu cloned to a SS. Original matching number and code block and transmission might also confirm LS-6 status if the numbers have never been messed with. Cool find if it is what its supposed to be.

didn't the build tag under the hood tell if it is real or not? My 68 Firebird had a metal tag attached to cowl area

I don't believe so. Yes there is a cowl tag but it does not spell out the engine. Check out this page. It kind of repeats its self though.

What's that saying about more SS's being on the street now than were made...?

Good luck on finding a real LS6

My friend I grew up with had a few LS6 Chevelle .The Tach I recall is a clue due to the higher redline.The buildsheet can behind door panel etc locations.If you know the dealer there might be a registry .Similar to the Yenkos

[Ghoste]

The metal tag under the cowl just has trim and paint info basically, nothing on drivetrain or other options.  Is there information behind the heater on all GM's?  There is some kind of way to prove a Chev's legitimacy on some of them there I thought but it would be doubtful that the seller would let you remove the heater box to find it.
Wasn't the LS6 actually produced in greater numbers than the LS5?

[hemi24]

Thank guys for the help it does have the build sheet and on it says LS6 so i guess i am ok there the motor long gone so now where can i find a true LS6 date code motor.

4 bolt main block. I would imagine they are around. Date correct might be tough. Should be a 512 casting I believe.

Does anyone know anymore on the heater tag Ghoste refers to?? I'd like to know if there is such a tag.

[Ghoste]

If you are talking about under the heater box, I'm not even sure it's a tag or a stamping right into the panel.  I'll try and find out more from the Chevy guy that told me about it.

[maxwellwedge]

Yes - Panel stamped - there will be a frame stamping as well....http://chevellestuff.net/qd/frames.htm

Protect-O-Plate is good to have as well.....I "flipped" this in p-shop so you can read it - they are backwards.

This one was for my first LS6

[Davtona]

Yes - Panel stamped - there will be a frame stamping as well

I new about the frame stamping and should know about the heater box one. Maybe long ago forgotton about that one. But aren't these VIN numbers only. They will not tell engine size correct?? So would not verify LS-6 or any other engine for that matter.

Same thing with Hemi Cudas..440+6 cars....etc...Anything that's worth money.
I mean, nobody clones a 4dr sedan with a 230 6....SS, RS/SS, LS6, 440+6, Hemi, 340+6, Yenko, GT 500, GT 350, BOSS 302, and so on and so on...

[Davtona]

Does protect-o plate prove it also?? Does the CRV in your plate stand for LS-6 4 speed coded block Jim?

It definitely helps to have the P-O-P - along with the sheet and a careful scrutiny of all the numbers. The Mopar stuff is great because the engine code is in the VIN....we are luckier in that respect.

Yes to the CRV question.

[Chryco Psycho]

I know my Aquaintance had no problem building Fake LS6 cars , he would do 2 or 3 at a time , find clean bodies & just add the right parts to make it an LS6 , obviously without a build sheet ! , The Hemi & 440+6 cars are similar in that there are more around than ever but you can  easily tell they are cloned not genuine , the LS6 you simply cannot prove if they are legitimate or not without the paperwork so yeah there are more now than there ever were

[maxwellwedge]

Yes - Correct. But - It could be a piece to the puzzle with the dates etc.

I didn't explain well:
My point is that Chevy's are easier to clone and pass off as "real"... Chryco said it better...

remember the ls6 was just an option that you could get on a malibu, el camion, monte carlo and chevell. the 136 prefix in the vin and the 138 prefix in the vin helps to i.d. the car. i believe 136 was for a malibu and 138 for chevell. bow tie did a bad thing in 70 with it's car i.d. they are the easiest to fake . the P.O.P helps in telling you what the car really is. you can take a 350 chevell and make it to a SS Ls6. the bad thing is the P.O.P was kind of like the build sheet for mopar, easy to lose.  mopar vin will tell you most of the important info, not so much with the bowtiie vin. good luck, buyer beware. my friend bought a really nice Ls6 SS chevell turned out to be a mailbu.
