Possible engine swaps for my 1971 280SE

Thank You. I appreciate it. That helps tremendously.

Has a W116 straight six engine / transmission (1980 280SE) been swapped into a W108 (1971 280SE)?

My concern is mostly fitment.

Because its a double overhead cam, will it fit the W108 engine compartment? The head seems rather wide compared to a single cam head.

Will the motor mount and tranny mounts align and bolt on?

Will I need to re-fabricate the driveshaft?

Thanks again to everyone for your patience.

Shadesh ,it's all a bolt in fit and doesn't require any cutting etc. The Wiring is a direct fit and the drive shaft should bolt straight up.
Regarding space,the same body also came with the 6.3 liter V8 which is 1 meter wide and over 1 meter high. No worries about space at all.
The twin cam engine uses almost the same block as the earlier single cam engine.

Thank You Mermad6.3. I hope this thread is useful to others as well, especially for those who are thinking of or are looking for an upgrade.

Awesome! Thanks.

I haven't read the whole threat, but just wanted to make folk aware of an engine for sale here in seattle. the woman spent $9000 (no joke, she has the receipt) having this 250SE motor rebuilt by the dealer then wrecked the car 3 months later. She's selling the car (euro-spec 250se - automatic) whole for $3000 obo. if anyone is interested i'll send contact info
