Default LS6 Verification

I found an LS6 and have the VIN#, but can't find anything about the car at all. Need some quick help to see if it's the real deal.

VIN#: 194671S101427

I'm trying to get the Trim Tag info as well.

Thanks for your help.

VG

The VIN won't tell you anything about which engine was in the car. Only the engine stamped-in numbers on the front-right of the block (at joint of cylinder head and block) will give info on that engine. The LS6 engines had either CPW (manual trans) or CPX (auto trans) codes in the engine stampings.

You could have an actual LS6 engine in a non-LS6 vehicle and no one would know it....except the S/N's of all the 1971 LS6 cars are already known. You could also have a car which has a fake engine stamping and a fake VIN. It happens, so buyer beware!

I'm sure someone with all the facts will clear up your "haze" with good info. Just be aware that there are a LOT of LS6 "clones" out there with owners who want to convince you that the one they are selling is "real".

P.S. Owning an LS6 clone is NOT a bad thing, if it was built correctly. But, you don't want to pay the BIG BUCK$ premium that a real car would get, if it's just a clone.

"Quick" should not be part of an LS6 Corvette purchase

Alan,

The LT1 w/ AC checks out but need to get a better picture of the block numbers. It's either a B or E, and Glenn needs confirmation to properly date it. It has some blemishes and some incorrect replacement parts but overall it pretty good shape. I can send you his report if you'd like to get a better idea.

The LS6 (maybe) is closer to home, about 6 hours away. It has no documentation and the guy bought it from a friend who owned it for 10 years. But I'd like to check her out first. The price makes me wary though, that it's a clone. But he's a car collector and is thinning the herd.

Thanks,
Brian

Hey 7t1,

Do you know where the s/n list of LS6's can be found?

Thanks,
VG

Alan,

Attached is a photo of the engine stamping that appears to have been re-stamped after the block was decked.
Below are the numbers that Bobbie listed in his notes:
Block 3963512
Heads 3946074
Intake 3963569
Transmission 3978764
Tag on Trans 931710wy
Bell Housing 3899621
Rear End CAX2770
Carburetor 3986195
Distributer 1112076
Alternator 1100543
Paint Code 973
Trim Code 400
Starter 1180400
Alternator 1100543
The car still has the electronic ignition box under the left front of the car.




Restamped. How will this affect value or authenticity?

Thanks,
VG

That restamp won't fool anyone due to the VERY early production of that VIN. That car came off the line sometime in Sept 1970.
No LS6 cars were produced that early in the 71 production run.

Hi,
The pad appears to have an assembly stamp of 0919 (September 19, 1970). That date agrees nicely with the vin sequence of 1427… the first week in October 1970.
QUITE an early LS-6 as HF points out!!!!
The swirl marks on the pad's surface indicate a grind out at some point or a block that's been decked since it left St.Louis?
Not really surprising that there's NO documentation with the car.
The parts on the engine might prove to be interesting $… (the carb for example), but do they actually affect what the car is or was at this point?
Regards,
Alan

I guess you might value the car as a 71 bb coupe (?) without it's original motor.

Whatever it used to be, or is claimed to be now...all the previous owners valued it so little that they chose to throw away all the documentation and deck the block and restamp it CPW. Does that make any sense to you? Why is it that only the supposedly super rare and valuable cars have such wild and hard to believe stories? If you buy a car with only a story...do you honestly think that you will be able to add more credibility to that story? How? As Alan said...value it as a '71 NOM BB coupe because that is exactly what it is. If that is what you want, then pay for the condition and nothing else.

The earliest documented LS6 is number 10931. For whatever reason, GM did not start building them until March 1, 1971. Anything before that is either a clone or bogus, whichever term you prefer. I forgot: also a "Tribute car". ��

LS-6's also had a fuel return line. Only LT-1's had a single fuel line.

From personal experience, I would get a tetanus shot before examining the car. Never know when you might get hurt.

No, I should have made that clear. That happened after a nightmare that when I went in the garage my precious '70 BB, 4-sp ragtop had been stolen and replaced with a Yugo.

Actually, I run that picture each August to celebrate a persistent loving wife, good doctors, good nurses, good re-hab specialist and LIFE itself! Sorry if it was offensive, but if any of you have any heart worries, go to the cardiologist as fast as your Vette will take you.
Your pal,

Not offensive to me.... I'm guessing that pic is one you are happy to have taken; you're still here!!!

An event like that does tend to change one's perspective on life, doesn't it?

Yes it does. I have lost 87 lbs. and now walk or ride my bike 30 mins a day. I'll get off site now before a gentle yet firm moderator tosses me in pixel prison. Best to you, 71.

Had that done the end of January, 2 days before my 70th birthday. Bad family history. Today I played in my 38th and 39th softball games this spring/summer. Very thankful for modern medicine!
