Default Value Question - 1970 LT-1

Hey everyone. I'm pretty new at looking at vettes, and I poked around the internet here after I found one that I think I might want at a reasonable price, also noticing that prices on these things tend to be all over the map. I've got a couple questions on the LT-1s. I do know this is a real LT-1, potentially buying from a very trustworthy source (family).

It's a convertible, 4-spd manual original but the issue with it is it has a non-original motor with a newer 400 ci in its place. How much is that a dealbreaker in the corvette world and how much does that kill the value? Interior looks pretty good, paint is fair with a little bit of bubbling. It's not really "for sale" but I was told to make an offer on it. What's fair for something like this? I was thinking of offering around $15,000.

Thanks for your help! Hopefully I'll be able to contribute to these boards if all works out.

well, first of all, without the original motor, the value has taken a big hit...then it comes down to verifying whether it is an LT-1, (which would be more valuable than the average 70' vette perhaps) does it come with any documentation to prove what the car was originally? POP, tank sticker, window sticker, history of ownership? tell us more about why your family member believes that it is an LT-1, and we'll try to help. Rick

An LT-1 without the LT-1 is not an LT-1. It used to be but now it's a forty year old used Corvette with a replacement engine.

a 70 convertible 4 speed genuine LT1 even NOM is easily worth 15K as a project.
the price should adjust if it has any doc, has no rust, and all the specific LT1 parts are there, title issues etc...

if the car has had many owners then you could have the most trustworthy family and it might still not be a real LT1.

not for sale, but make an offer, means "make me an offer I can't refuse". they are fishing for high offers.

good luck, let us know what happens.

This is the truth. Mike and Joe nailed it in the head. No need to say more. Good luck!

Well that's too bad. It sounds like the value's about where I pegged it though. It's pretty, but yeah, I might be bugged by not having the engine over time.

You want to ensure you are not paying a potential LT-1 price based on what the car used to be. That said, it might otherwise be a nice car.

Hi o,
I have a slightly different take.
A car that was in fact an Lt-! when it left St.Louis and has been restored with an acceptably casting dated and numbered block, AND all the other parts that were on a 70 LT-! such as intake, carb, manifolds, etc., still judges very well by NCRS standards.
Although in $ it would have a lower value than a car with it's original motor, it's a NICE car to own, and in my mind would be worth more than a car with just "any" replacement engine in it.
A 70 LT-! convertible is a very nice car to have! You'd just have to be careful that you don't get too much money in it, ("as though that's ever happened before!!!"), and be satisfied with it's slightly 'sullied reputation'.
At a good price this might be a nice car for someone.... maybe you?
Regards,
Alan

Default Agree!

Agree!

There are 2 key considerations:

1. First, what is a fair price for the Corvette like it is, with the NOM engine? check completed ebay sales, internet, hagerty, ect, ect to triangulate a price.

2. Is having the NOM motor, and the rest and how original, important to you? If it is not important to you, see #1.

Personally, if I could find a Corvette that I really liked for a very fair price (or great deal), I could get over the NOM motor, but that is just me. Some folks would not take a Corvette with a NOM motor, no matter how good a deal it was. And that is ok too. IMHO, this is all about what makes you happy, LOL's! Just make sure you know fully what you are buying and what a fair, honest market price is.

I am with Alan on this. A 70 LT-1 roadster is a relatively rare car and worth owning. I also agree without a 70 LT-1 engine it isn't all it can be. I am biased as I bought a 70 LT-1 roadster and have been restoring it. You can find all of the parts you need for a date correct engine but it isn't cheap. When you add in the paint you mentioned you could easily have $20K into bringing it back so now you have $35 into it and you can find an original for not to much more then that.

In my case finding the parts and doing the work is why I like the cars to begin with so it is worth it to me. If you don't like that end I still think a 70 roadster in decent shape is worth $15k all day.
I am picking up a NOS 70 LT-1 engine in May. When I do I will be selling many of the parts you will need to build a date correct engine if you have an interest.
