Hi, new member here. I was searching for info on dropping a 300E engine into a 190E 2.6. The 190 is clean but has a broken timing chain, I was thinking that a 3.0 engine is a logical replacement for a little more torque.

Is this a "plug and play" type of swap? Do I need to change any electronics or other accessories? The good news is that I have the 190 complete, so I could switch over anything I need. I know that both engines are essentially the same, the 190 is an 1989, does anyone know which years of 300 engine will plug right in? Lastly, how much increase in torque am I looking at between the two?

Thanks a ton in advance, and I apologize if this has been covered to death already, if so maybe someone can link me to the appropriate thread.
