I wish I had the original engine for my car. Not having it and knowing I will likely never run across it makes decisions about what to put in its place easier. Well it should but I punish myself, so I acquired a 2.8 from a ‘71.
I think in the broader scale, perhaps someday originality will be key with these cars but with M30s having been made from 1968 to 1993 and it being relatively easy to make a later motor with similar architecture and a decent bump in power work along with other subtle things that make the car drive better and not look out of place, there seems to be about equal value in that versus an original numbers matching 3.0 CS. 2800s, I think people are still struggling with the heavier badge and how long it takes to say.
