Are you a Mopar purist?

Thought the 318 in '64 Dart might be tits up and wanted the car to be running and found a 340.
318 probably OK and will be sitting. What good is that ?
There's a '37 Olds for sale locally that needs windshield, engine and trans to drive legally on the street.
Why the Hell not ?
