So i have a 2009 C63 AMG got it tune is fun and all just want something a little scary lol so ive been thinking of getting a SC but before that i wanted to know if i should grab a new m156 with lower miles or should i be fine.

PS.i got around 108k miles on her now

 

Go for it! These engines are stout. As long as you take care of the known weak points, i.e. head bolts and pulleys, you should be fine.
I think your bigger problem will be finding traction from all that power.

 

Yea was just wondering only problem I’ve had with the engine is the normal bull**** camshaft adjuster rattle
