The above is true, but it depends on the car. The added value that my 318 Duster has from it's numbers matching original drivetrain over a similarly running, same displacement non matching is $0.00.
Definitely. Percieved value of the make and model factors into it as well.
As for the comment regarding 340 cars? Collectors are up to speed on the 340's place in Mopar history. 20 years ago, nobody wanted a 340 car. Nobody even wanted a 340 E-body. Hemi's and 440 cars were desiable back then. 383 E-bodies were commanding more than 340 cars. Collectors nowadays are much more educated. The 340 was a performance option over the 383 in an E-body and viewed as more desirable. If you look at market pricing for 340 cars, they can match or eclipse a comparable 383 car.
Same with A-bodies. 20 years ago, nobody even looked at a 340 A-body. Back then, almost all of them were numbers matching cars. I had friends that had the following: '69 Dart GTS 340 & '73 Dart Sport 340. They bought them cheap and sold them cheap. Nowadays, its not as easy to get your hands on a rust free, original, running, numbers matching '69 Dart GTS 340...and definitely not cheap. The more I look online, 70 & 71 340 A-bodies are into the 20K-30K range restored. The market is catching up to the A-body. 20 years ago, nobody wanted a '73 Cuda or Challenger. Have anyone tried pricing one lately? The same will happen to '73 and '74 A-bodies. It's only a mater of time. The older these cars get and as the more exotic big block cars get scooped up, collectors will find another market segment to target.
