At a quick glance the window sticker fooled me....I didn't even read all the way down. I wonder where this car is located...I'm about 50 miles north of Atlanta.

if your requirements are an LT1 then yes, this is not the car you want.
depending on the asking price looks like a nice fairly well loaded red 2 top leather AC convertible. if it is in decent shape, then it is probably worth a good amount with and without its base original engine.

and major kudos to you for at least planning on going to see it for a final inspection prior to purchase.

since you are passing on the car can you provide a link and asking price? I would like to at least see some pics.

I will agree with the others. This is likely a base motor car being passed as a LT-1. The window sticker fonts are wrong and too sharp. We have a 1970 LT-1, that my father bought new, that has a never affixed window sticker. Alan71, Terry M. I think has a copy of it if you are interested in it (looks just like his, Mulsanne Blue/Blue interior).

Unless that car can show a valid tank siicker, single fuel line, correct stamped block, correct tach, transistor ignition, etc. it is not a real LT-1. If you are not looking for an original LT-1 that one may be fine, just don't pay the price for a real LT-1. Contact your local NCRS chapter to see if someone could also look at a car if you are interested in originality.

Hi VG,
Nice LOOKING car.
The tachometer isn't the correct redline for a 71 LT-! car.
At the right price it might be a very nice car for someone.
Maybe even you?
Regards,
Alan

This is a nice looking car, but clearly is not an LT1. If that does not matter and the owner does not think he is sitting on a gold mine, it could be a nice modded car to buy.

Just go in with your eyes wide open. The seller may actually think it is a LT1 so he may not budge. If enough people look at it and tell him otherwise, he may eventually accept it.

There is no price listed, but if I were looking for a modded roadster, I would at least give this one a look. If the underside and birdcage is rust free, I would think this one would pull mid to upper 30s.

Owner was asking $45,000, down from $55,000. Then settled in at $44,000, if it was a real LT1.

Thanks for all your help CFer's, I didn't want to end up on a back road naked and without $44k in cash.

I also saw this car on Craig's list. I did not ask more than the price which seemed real good for an LT-1. I just purchased a C3 days earlier so I'm out the market for now.

In an email the seller supplies an information sheet on the car that I have posted here:
https://drive.google.com/open?id=0B6...hpWUpINVJueHpB

It would be nice if those more knowledgeable about LT-1's could look this over and share their opinion with us all.
Thanks

In his description; besides the "350hp LT-1 package" it has the "rock crusher" M-21 trans. It's one of a kind.

I have a '71 LT-1 and live in the Atlanta area (happy to help you out if needed). Things I see that are wrong:
  • Tach
  • Carb (should be 780 CFM 4801)
  • Intake
  • 350HP (should be 330)

I'm sure there is more - I have a list of LT-1 specific items to look for that I harvested via various sources. For example, a 1971 LT-1 should have:
  • 6500 redline
  • 1 Fuel-line on passenger side
  • No radiator overflow tank
  • Transmission cross-member should be welded to ladder frame (not bolted)
  • Engine code should end in CGZ
  • 5-blade radiator fan
  • Open element 14" air cleaner
  • Aluminum intake manifold and valve covers
  • Transitorized ignition
  • No A/C
  • No holes on hood behind emblem

Hi ny,

Here's a comment about the car and also some LT-! information that you asked about.

This ad is filled with errors and car salesman lingo…. it even plays the "please buy it cause I'm sick" card.

There are lots of parts and conditions that make an LT-! an LT-!.
Here's a long list that has been posted before.

None of these matter in this case though because no 1971 LT-! cars were equipped with air conditioning…. which leaves 2 possibilities:
It was an LT-! that had a/c added to it
or
It was an a/c car that had an LT-! engine added to it.
Which of these it is really doesn't matter.
Regards,
Alan



Here's the list:
1st. No 1970 or 1971 LT-1 had A/C

2nd. Emmission sticker on fire wall behind master cylinder should have letters AX on upper left corner for a 71.

3rd. All LT-1's are 4 speeds. (M20 was std , M21/M22 were optional)

4th. Tach has 6,500 RPM red line on 1970 & 1971 and on 72's w/o AC . 5600 for 72 with a/c

5th. All 71 LT-1's came with A.I.R. system. If removed should still have manifolds with holes for the tubes, Car may have headers and if so ask to see old manifolds.

6th. LT-1's had copper radiator W/O a overflow canisiter on the passanger side fenderwell. There should also be no holes whers one had been mounted.


7th. All 70 / 71 LT-1's had Tranisitor Ign. system. That may have been removed. But if it is removed look for the 3 holes on the front face of the driver side inner fender well where the Amplifer box was mounter.

Take a flashlight and look in front of the front wheel or open hood and look at it from the front side. 2 holes on bottom and 1 on top. No TI on the 72 LT-1


8th. Should have a Winters snowflake intake manifold with casting # 3959594
for 1971 and 1972, per NCRS, 1970 should be #3972110. Both manifolds are aluminum (my addition).


9th. LT-1's had a Holley carb. so there is only 1 fuel line , no return line like a quadra-jet carb. Look along frame rail on passanger side for the single line. Also the fuel tank is different. There should be no nipple on the passanger side, side wall for a return line.

If you lay on your back under the rear wheel you can reach your hand up and feel for an indention on the passanger side. If there is a nipple that is capped off , then beware.

Also the single fuel line on a LT-1 was not the same line that was used to feed fuel on the 2 line set up. So if someone removed the return line the look of the 3/8 line is still different. Not a big difference but if you can look at a car with a 2 line set up then you can see what you do not want to find.

10th. LT-1's had solid lifters , but if the car does not then that is not to big a red flag. Many people do not like them and may have replaced with HYD. lifters during a rebuild.


11th. The hardest to fake and most expensive would be the 4 bolt main block. No # on the outside of the block can verify this.

Only way to verify is to remove the pan or have a lighted optical viewer and remove the drain plug.


12th. LT-1's use 2.5" exhaust pipes like the big block cars. But the manifolds were still 2" set up. So the pipes flair from 2 to 2.5" about 6 inches from the manifold. The exhaust hangar at the trans is also different. Look on line at the Corvette Central site and you can see both 2" and 2.5" hangars.

13th. As I recall the highest rear end gear was 3:36 if trans was a M20

And id Trans was a M21 or M22 the 3:55 was highest gear

M20 3:36 Economy

3:55 Standard

3:70 Performance


M21 / M22

3:55 Economy

3:70 Standard

4:11 Performance

14th. The 71 /71 LT-1 Aluminum valve covers should have a rubber oil cap not a twist in. These covers are very hard to find. All the catalouges sell the twist in cap style.

15th. LT-1's have the same heavy duty half shaft retainers as big block cars. look at the rear end side yokes, there should be caps with bolts. Base cars used U bolts with nuts.

16th. The rocker arms have a letter O stamped in them.

17th. The balancer on the crankshaft is an 8" unit not a 6"

Alan's post should be a sticky for anyone considering an LT-1. Great reference!

Hi rb,
The LT-! information is a copy of someone else's effort.
I'm sorry, but I've lost track of WHO did such a thorough job!

Alan

Not that it really matters much at this point, but I don't see the mis-spelled 'telescopic' on the window sticker.

The abbreviated window sticker was not the one in question, that is from mine to point out the one the OP had shown didn't include the LT-1 RPO

Funny, the owner of the fake LT1 never called me back. I probably would have paid $30k for it.
