How much Nitrous?

Hey everyone! Happy New Year! OK, here's the question, how much nitrous can a stock block(2-bolt main) handle? Have all-forged internals from Lunati(crank,H-beam rods) Icon pistons, Lunati roller cam@.738"lift and 265/272 duration. Lunati lifters, Manley severe-duty valves(2.300/1.900) in a set of BOSS heads. So, Bruno or Induction Solutions, What is your suggestion? Appreciate any input, thanks

BTW, forgot to say, all ARP studs for heads and mains, using a main stud girdle that is 5/8" thick. Also, all premium bearings.
