I am the owner of a true 1970 370hp 350 and i was looking to see the estimated value of the engine. The engine is stock for the exception of being bored .30 over and headers. I also have the original carburetor but its not currently on the engine. The engine runs fine and still has great power! I can attach some pics and get the engine codes tomorrow. Thanks in advance for the help! Also mods please move if i put it in the wrong forum!

Pics are from my phone so they arn't the greatest. The car has been sitting in a garage waiting to be restored since the mid 80s so everything is a bit dusty.

 

Okay...are you saying you have only the engine? or are you saying you have the the LT-1 and the Corvette to go with it?

 

From my point of view a used engine is a used engine, especially one with headers then I tend to suspect it has seen a good degree of high rpm use. Also, one that is already 30 over, will probably need to go 60 over, maxing out your engine...
Any 40 year old engine will have either new parts in it which then just makes it another used engine, or it has original parts and in my opinion is about ready to let go.
It is probably a 010 cast engine, a dime a dozen, and I would only need it for its casting date.

another corvette engine with another corvette engine stamp sitting in my car would do nothing to raise the premium on my car since it would be just another NOM. As a result, I would not pay a premium on your engine.

One who buys this engine for any premium will only be looking at specific casting dates of the parts. Then they would have to broach and stamp it to their car, bringing up another ethical question and lowering the number of buyers out there. These engines also cost hundreds to ship and are a hassle to ship and receive, and this drops down the price a buyer will pay.

it is just another 350 unless you have the car that it goes to, or maybe you can find a buyer with a LT1 that wants it based on it's casting dates.


or maybe I am all wet and someone will say ' wow, a LT1' and pay your price... I suspect there is a good degree of truth to this statement too.

 

Well, what do you really have there. A .030 over 4 bolt block that may or may not need to be bored again. A steel crank that may or may not need to be turned. A set of pink rods, that can be replaced rather inexpensively with much better pieces. A set of iron 2.02 heads that may or may not be worn out and can again be replaced with much better heads.

Don't get me wrong, I also have a '70 LT-1 sitting under my bench and it's all standard with about 20k miles and it hasn't been messed with. It's a CE motor that was in my '69 when I bought it. Honestly, If I ever decide to sell it, I wouldn't expect to get more than $400-$500 for it.

 

First in line!

 

The only real value to that engine is to you...since you have the car it came out of. If you had that engine back in your car in stock condition, your car's value would probably be about $3000-5000 higher than it is now (regardless of what engine you have in it now). If you don't think that the engine is worth keeping , you can disassemble it and probably sell the various components for $1000 or so. Hmmmm.... That doesn't sound like that good of a deal.... $3000-5000 if it's in my car vs. $1000 if I sell the parts (or $500 if I sell the entire engine). But, to each his/her own...

 

Well its currently in my nova and it only had around 8k miles on it since it was bored. I was not sure if it was worth anything or not. I thought i would inquire about it seeing as i had another thread about my 65 396/425.

 

It would be worth plenty to Corvette owner the motor came out of, isn't there a LT1 equipped registry somewhere you can look up the Vin numbers ?

I may be way off base here so please bear with me, I am far from the original equipment guy, even though mine is actually a numbers matching C3 as I have all the parts taken off over the years

 

When you stated that you were the owner of a "1970 370hp 350", I thought you meant "vehicle" rather than "engine". I think the best value you can receive for the engine is to keep it and use it...unless you can find the owner of the original car and learn that he/she actually wants to get the engine back. You can always put the complete engine on eBay with a reserve value that would be equal to the value of the individual [saleable] components.

 

The owner of a '70 LT-1, with a NOM that is NOT from a '70 LT-1 Corvette, would definitely be interested in that motor. Since '70 was the lowest year of Corvette production, which also had the highest hp LT-1 engine, that's also in your favor. Try the NCRS forum also and list the stamp pad number. The owner of that LT-1 might be waiting to find that engine. That would be a happy day for both of you.

....by the way....the correct carb for LT-1's ALONE can go for $1,000. So parts OR whole, it's worth some bucks.

 

Thanks for the info! I didnt have time to get the numbers off the engine today, but i will try and get them posted soon.

 

Hi ab,
I agree with v4e that the NCRS may be the best way to find out if the car that your engine came from is still out there. But rather than the Tech Board, I'd try an ad in the classified magazine the NCRS puts out every other month... THE DRIVELINE.
Also, you might try talking to Drew Papsun, (Google), he has been compiling a LT-! survey for many years and may know of the car your engine came from.
You could make someone VERY happy!
Regards,
Alan

 

FWIW: you could get an LT-1 in a Nova. What you have could be original; possibly not Corvette, but original.

You need the numbers off the pad.

 

The Yenko Deuce came with the LT-1. I can find references to Baldwin Motion smallblock based Novas but not specifically the LT-1. Either way, I'm pretty sure he'd have some history indicating a link to one of those companies if his car came with the LT-1 and it would be a high $$$ car. Chevy didn't build a Nova with the LT-1- Vettes and Z28s only.

 

I should have them later tonight! The nova is a 68 SS so the motor would not of came stock in the car.

 

Here are the numbers:
Block:3970010
Block front pad: 70s416957 v0706ctk

I didnt have time to pull the valve covers off tonight so no head numbers.

 

Hi,
WELL!!!
If that car is around your ctk engine would make the owner pretty happy UNLESS he already believes his car has the 'original' engine!?
Regards,
Alan

 

is ctk rare?

 

Well there were less than 1,300 LT-1's produced in 1970 (the fewest). Your VIN stamp seems to jive with the production date on the block. So your's was one of the last produced, in July of 1970. Just don't let anything happen to that stamp if the block is ever decked. I was very careful about that in the mid-80's with my '66 427/425 and it paid off. As Alan said, you and the car's owner should talk.

 

I tried to find the production number of the car it belonged to, but came up empty. I am not exactly sure how i would look it up accurately.
