15lbs=how much nitrous?

I recently converted from efi to carb. i had a t trim sc pushing 15+ lbs of boost.needless to say i have a very sturdy bottom end 306 and also a big cam, big ported aluminum heads with 1.6 shaft mount rockers long tube headers off road h pipe and 2 1/2 inch exaust and plan on a 750 carb. and taking the motor up around 6500. so how much nitrous can i handle TOPS. Thanks for any input guys.:hail2:
 
I would guess a 150 shot... Nitrous is a LOT more shock than a blower.. Its not an easy on or off.. Its either Off, or WTFO. You can blow up a motor on the gas real easily.. but with a proper tune and a decent short block you will have all the fun you can handle.. I have sprayed a 150 shot on my car for a while with no problems...
