GMECM and Crank Sensors

[jtyler]

For yet another project, is there a nice reliable, relatively easy to mount crank sensor that interfaces easily to the GM ECM's you favor?  
In this case a dist is not an option.  

I have provisions to build a mount, make/adapt a crank wheel of some type or precisely install magnets in a pulley or even a flywheel.

Does the GM DIS have 5 or 6k rpm limits, something I read somewhere indicated that, but they may have been talking about HEI coils?  All this stuff I am playing with needs to make it 
to 6.5K, the race app at least 8500.
