355 buildup questions inside?

I'm looking to build a 355 LT1 that I can occasionally spray a little nitrous(150 shot) through it and not have ANY problems! Can I get some suggestions on what parts you would use on this set-up and what kind of money am I looking at?

Right now I'm running a 6lb Powerdyne supercharger on my stock motor its running really good I'm just looking on changing over to the nitrous side.

I will move this over to LT1 Tech since this is 'advanced' persay, you should get more responses and opinions there also on this subject.

Thanks!
