340 cars value question

Is there any extra value of a factory 340 or 383 car if the original engine and other parts are long gone?

I see cars listed all the time that are factory 340 & 383 cars but you look at the pictures and all the high dollar items like engine block, intake, carb, exhaust manifolds, stock wheels, hub caps, and on and on are gone. Yet the owner seems to think the car is worth more because it's a factory 340/383 car.

I personally don't value a 340 car missing all the factory goodies differently than say an identical equipped car that came with a slant 6 from the factory. Just wondering what the consensus was among the group.


a 340 or 383 car will always bring more money then a 318 or slant car in the same condition ( we are talking abodies here right?). but non numbers matching numbers will drop the value some. theres nothing like matching numbers. closest thing is all date coded stuff. its about as close to matching numbers as you can get sometimes but the matching number car will be worth more.
