Cure for lazy Magnum...Has anyone built a Magnum for 7k+ revs?

Nascar guys push 9400 rpm all the time. 7000 rpm sounds like your building it for Grandma. Step up to the plate and go Big or go Home.

Yeah....LOTS of NASCAR 50 year old cars seen in commuter traffic....where 9400 rpms make the most sense.
