      Congratulations! Well, the value goes down for sure but a little less if you can PROVE the engine/trans were out of another 440+6 car. I'm not sure, but if you can do that unless you know of an A12 VIN registry with your block/trans VIN listed???? How much will it lower the value?.... no idea.

      p.s. unless you flip cars for a living, snap out of it & keep that one!

        I suppose it all depends on the buyer. Personally I believe a car is only original once. So a "survivor" with a different block would have less value than if it had the original. On the other hand, a "restored" car could be a complete re-body so big deal if the block got swapped too.

        Just my thinking!

          There was a knock-dead gorgeous a12 RR at Carlisle last year - virtually identical to yours. Same deal - not numbers matching block. Didn't seem to be affecting the asking price. For all I know maybe you bought that car !!

          1st - Congrats on the awards at Good Guys.
          2nd - Depends on the buying audience. Saw a '67 Mustang fastback at Barret-Jackson, Salvage Title, nicely done, $47,000. Sometimes a car just "speaks" to a person.

          I believe as these cars thin out further, the effect on value will become less to the general buyer. It'll still be a downgrade for the concourse or museum collector.

          Those guys should never be used in the equation. They usually have deeper pockets than the average guy and will pay ridiculous money for a car they want. A few years later they're bored with dusting the cars off and they're liquidating at a fraction of the cost.

          The question as to whether the OPs car value is diminished by not having the original engine and trans is dependent of many factors - time, place, interested buyers, car market, etc. "Those guys" do factor in to the market value of cars. If a car is hot/trendy, they drive the price up; if not, the prices fall. That's why people who have cars that have been rotting in swamp for 30 years are asking $10k, and why some are asking $400 for a bumper jack. If you are selling, you never know who is going to show interest in the car. Maybe the only person that takes interest in the car is the deep pocket, ridiculous money, guy/gal, who really wants the car.

            Unless your planning on selling it to a complete
            purist it means little or nothing.
            There were a hell of alot of our cars with toasted
            engine back then.
            Few actually survived day to day street racing.
            Enjoy what you have,not that big of a deal.

                It's simple. It won't have the value of an original drive train. Then again, many cars won't since we beat the hell outta these cars back then. So what. It's still the best street muscle car of the era in my view.

                  Value is all relative to who owns the piece and who wants to purchase it. But my perception is that cars that were factory equipped multiple carbs or special interest cars as the wing cars are hurt more than the typical muscle car being non-numbers matching. The buyers of these cars will typically pay a premium for documented matching numbers. You asked the question, so my feelings is that it can be as much as 20% for an average restored driver. If it is a highly detailed restoration with a correct date coded block / transmission; then I feel that number is in the 10% range. An replacement A12 block does help in a highly restored car, so that number may be as low as 5%.

                  Personally, I am not so hung up on the numbers matching thing, but when you start looking to pay six figures for a car, then matching numbers will be a huge plus. The sad thing about it is that are a lots of cars out there claiming to be original matching numbers, but unfortunately they are restamps. That is the reason that prices can vary so greatly for comparable cars. Pedigree with documentation adds a tremendous value to most of these collector cars.
