Opti for just the Optical Sensor

[1SlowFormula]

OK, guys I know I have read this somewhere in the past, but figured I would bring it up again since searching sin't helping me.

So we all know the limitations of the opti and since I am building a new engine combo I am debating on engine management and need to get something that will let me rev a 370ish ci LT1 upwards of 8K RPM's. I know there are a ton of options out there for moving away from the opti, but then I wonder how much of an LT1 would I have? So I keep coming back to trying to figure out how to keep the opti for the optical sensor to trigger the engine managemant rather than trying to throw one a crank sensor or anything like that. I would still run a seperate dizzy fro firing the plugs since that is what contributes to killing opti's at higher RPM's, so that should allow the opti to freely spin that high, right?

Also, if I keep the opti, what is the best way to utilize it? Has anyone done it?
