View Full Version : Reuniting a car with its born-with motor

Just how much does an authentic born-with motor add to the value of a rare car?

And... what would be a reasonable way of determining the value of that original matching / born-with motor - fair to both the owner of the car and the owner of the motor?

Assume the car is an unrestored, but documented L78 convertible and there are no secrets between the parties.

I have the born with l78 for my 67 Ssrs l78 conv camaro. I have offered 40,000 for my car which is a stripped shell that sat in a field for years. The owner of my car would not accept my offer. If the roles were reversed I would pay 12,000-15,000 for the motor.

I paid a little north of 10k for my numbers matching motor to my LS6.

20% in my opinion. Jeff

LuzL78,

I don't understand your comment. Are you saying you own the engine but not the car? If so, why do you call it your car?

Jason, it was my first car I ever bought. I always have called it my car even though I don't own it. Just a sentimental thing.

I thought on a 69 z that the original engine adds 20%.
10k for a numbers matching ls6 is a deal. You couldn't build a new one for that. I have a new dart block 383 and around 8 in it with no intake, carb or exhaust

This is how it was explained to me, figure what the car is worth without the original motor and then with it....then divide the difference in half.

For example, if the car is worth $30k as is or $50k with the original motor, the sale price of the motor should be half of $20k which is $10k.

Well put Kurt

I feel both parties should give a little, sometimes people hold original blocks or original documents hostage (talked to a super nice car guy recently who has a low mile 69 Chevelle and the original owner is holding the papers) for big bucks and IMHO are not people I would call a Friend.

Absolute born with block in good/bad condition, complete engine w/ original components or not also their condition all should have a bearing on the value too.
Congrats if this is the original lump to your car Helmut!

I don't like the idea however by that rationale, It is then much more profitable for a person so inclined to profit to wait until the car was restored or value otherwise increased before offering the engine.
IF we use the following formula -
A backyard hack resto L78 is worth half (X/2) what a professional restoration is worth (X).
The engine block difference is the same 20% discount of selling price.
Mathematically this is half (20% of X/2) what the pro car difference in raw dollars (20% of X).
Which gives you a figure of (10% of X) split in half yields 5% of X as the negotiated price.
However waiting for the owner to expend resources to restore the vehicle stands to yield the seller 10% of X.

OR
it would be more profitable to hack resto so you could get an engine block...
either way HOLDING HOSTAGES IS WRONG.

Wish it were the original motor for my car Pete... I'd sure pay a fair price for it.

I don't think it matters whether the car is restored or not. I agree that the born with motor likely adds 20%.... but, 20% of the restored value of the car.

Yep X3, some of us can find the parts we need but can't afford to pay the prices for them. Greed kills.
