No offense to the SRT guys, but other than the motor I prefer the regular Crossfire. If they would have just put only the supercharged engine in the regular Crossfire I would have liked it a lot better.

I was just reading some information about swapping a 430 engine into a CLK320 and it sounded pretty straight forward. They used the ECU from the 430. The CLK and SLK/Crossfire share the same basic engine bay. Any special parts if needed like exhaust manifolds could come from the C43. Mercedes started putting V8's into the C class chassis in 1998 with the C43 AMG.
