Have not done it with a Mercedes, but a couple thoughts: the crate 350 will be a good deal heavier than the 3.0 litre 6. Don't know about the JDM.
The heavier engine might be hard on the suspension and it will definitely affect handling.
It can be done, but the resale of the car will drop to nearly nothing.
For reasons that are probably more emotional than anything else -- mixed transplants sit in a funny place in the used auto world.
Did a conversion on a Jaguar 3.8 many years ago to a 350 when the 3.8 was an awful engine in the first place (unlike the MBZ 3.0).
We couldn't give the car away a year later.
