Probably sounds stupid, but I'm curious. The engine in my 2010 c300 4matic is getting up there in miles so I'm wondering rather than selling could I try putting the 2012 c350 engine (costs around $1,200 for the engine itself) into my c300 4matic. now I know I'm gonna need an upgraded fuel pump and definitely some kind of new ecu (still researching about the ecu and all the implications) If I were to have this done, im definitely going to a have this put together by a professional, but I just need some feedback on other parts that I would need to be buy in order for this to maybe be possible.

How many miles are you at?

right now 185,000 nothing is breaking on it and I been keeping up in the maintenance. Just wanted an engine with a little more power
