Default Corvette Value Comparison and Consideration Thread

Well, by popular demand I decided to start a thread regarding Corvette valuations.

Let's start the discussion on what folks feel would be the difference in value between (lets create a hypothetical) a 1971 LS5 corvette that has the original LS5 motor against the same car that has a NOM in it in the same condition?

My research says it can be easily as high as 50%. Any thoughts?

By the way, any year car corvette be discussed. Not limited to 1971s. Consider this thread open to a healthy and educational debate.

OK, I'll bite.. 71 LS5? Not that rare, I'd guess 20 - 30%.

If we're talking about an LS6, I'd guess it could be as high as 50%.

So you are the outlier. Does this mean you lean to the left or the right?

I got you marked for a 100 percent decrease in value!

You know something interesting comment you making about LS5 being not that rare.

Although many more of these LS5 motors were made than LT-1 is seemed to me LT-1 motors popped up more often in my search.

As for me, I desired the 454 more than the LT-1. That to me has an affect on value. Desirability.

Okay got you marked for 20% to 30%. Cool beans!

Okay it has been amended!

Okay tough guy.

Take a look at this car. Pay close attention to the tach. 5400 instead of 5600. Look at the rest of the car. What is going on with this car and is this pricing appropriate?

Me thinks this is a small block car that has a LS5 NOM in it and the hood has been changed to a big block.

Me thinks, way overpriced!!!!!!!

That car is wrong on so many levels, yes appears to be a small block car with a BB transplant & hood.

Ok so how much does it take a hit due to NOM and born a small block? Should it be priced less than an original small block? Or does the NOM BB carry any premium?

It's amazing how many cars out there all have their "original engine" in it. It took me some time to find a car that the owner and the inspector agreed that they were original.

My personal opinion, it depends on how 'correct' the transformation is going by NCRS judging standards. I'd be more interested in one which was originally a BB. I have no plans to buy any more Corvettes, just a thought.

Aren't they all original, numbers matching? Any which weren't were scrapped or turned into restomods?

I don't remember the last time I ran across an ad for a 'correct' non-numbers matching Corvette. Could some be miraculous recoveries of the original engine through restamping?

How hard is it to change a tach? Many dont do it? Lazy, cheap, stupid or a little of all?

Oh just to let you know feel free to dissect any car that is presented here. It all leads to value. For starters that tach should red line at 5600 for a big block. It reads for a small block.

It really would depend on the condition of the car. What would be the difference on price for a 1971 LS5, all else equal:
  1. Two pieces of junk
  2. Two driver quality cars
  3. Two top flight cars

If you have a NOM top flight, how can you devalue it 20-50% compared to another original motor top flight?

Now, your market may be smaller, but my bet is a person buying a NOM has different goals than someone who wants an original motor.

I will take either, as long as it is a clean car.

What percent of NOM cars achieve a top flight award? I would imagine this number would be small.
