you're right v8's turn slower because they have two extra pistons, and that gives the engine more usable torque at a lower rpm, so you have to rev a little higher to make the same amount of hp and TQ with the v6. also you have the 5 speed trans, not sure but I know SRT6 has a numerically lower final drive in the diff. as compared to the limited crossfire. Hey maybe you can figure out a way to swap in the slk350 6 seed auto.
I'll have to see what my standard trands revs at in 6th gear @ 60 mph.
