MB/AMG seem to be bending over backwards to say there won't be an R171 SLK63, but with the SLK350 getting upgraded to 300hp for the 2008 midlife upgrade, will AMG leave the SLK55 alone? Well what about this possibility - dumping the SOHC 5.4 for the DOHC 5.4 just recently introduced in several lines?

Right now the SLK is the last model to use the older SOHC 5.4, so why wouldn't MB want to end it completely and use the DOHC version only? Since it is basically a DOHC head on the same block as the SOHC version uses, the fitment issues surrounding the new 6.3 would be eliminated. And with a boost of 20, aproximately, in both hp and torque, it would carry the SLK55 gracefully to the end of the R171 cycle. Hell, they wouldn't even have to change the name - SLK55 since displacement for both SOHC and DOHC is the same.
