[JT912]

A 30xxxx or 50xxxx VIN will always be a factory built 911 regardless of the powerplant. A 35xxxx, 45xxxx, or 46xxxx VIN will always be a factory built 912 regardless of the powerplant. Much like putting a Chevy 350 into a Mustang doesn't make the new car a Chevy. Yes a 912 with something other than 616 will have lost it's soul and is considered a renegade, hybrid, modified or bastard. When you register a modified 912, the registration will still say 912. Much like kit cars built on bug platforms. They are registered as VW. I will bet the above car is titled and registered as a '68 912.
What is silly about this car is that it isn't really much different than a '74 -'77 911 so it isn't like they built a radically new car. Just one that is a few inches shorter. Probably would have been much easier to section out two inches from a 2.7L car and then call it a SWB. That I would like to see.
