i built my 383 to run on nitrous. i plan on running at least a 200 shot. is there anything i need to do to help vent the bottom end? could i add a breather in the valve cover? i am unsure if that will mess with the way it runs as far as any sensors or what not. thanks for any help.

 

I spray a 300-shot, and use a completely stock PCV system. No breather. No evidence of any oil carryover to the throttle body.
