Newby to nitrous fuel system and setup

Ok guys sorry for the hiatus -

Rings were gapped for nitrous during assembly - I do not know the gaps though - was professionally built though and I trust him - said it should handle a 100hp shot fine if tuned properly - again will be professionally tuned on a chassis dyno

What about intake manifold? Will I need to swap to a single plane?

EFI comment- I am wanting to run 1 fuel pump in the system, I assumed I would need an electric pump capable of EFI pressure/flow to be able to feed both systems - I won't be able to run a Holley Blue or Black pump to feed both the systems? The Stealth pumps fit in a stock mopar tank? never knew that.. and not much more than an A1000 - I would like to avoid a sump, my car is stock height but just don't want to buy another brand new tank LOL even if they are cheap..

It is carb'd and staying that way.. has a Holley FPR now - I will be looking into a return style FPR from the same manufacture as the pump I ultimately get

Ignition will need an upgrade yes to pull timing, as it's at 20-21* base and 41* total, and don't want to deal with having to hook the timing light up a ton..

No Progressive controller, just a button and micro switch (WOT switch) is the plan
Will have a FP cut off as well

Motor has KB dome hypers - 11:1 static compression

Converter is a Hughes 3500 stall - no anti baloon plates or anything - just a basic non lock up.

My biggest fear is the trans being stock honestly

Let's say budget of budget builds? What about using the stock fuel system I have now that is proven for the motor and run a dedicated fuel system for the nitrous with a separate cell in the trunk?

But ya it is a nice car, a fresh build with 10 miles on it, and am planning 100hp shot no more than that... I'll build a new motor if I need more

I bought a used NX kit locally for $150 with a half full bottle.. LOL $150 was to good to pass up and am told it has 100hp jets in it - it's pretty rough and unsafe looking for my standards so I'll end up going through the system and probably replace everything LOL

What about track legal? Blow down tube? should I relocate the battery to the trunk? Purge kits is next, then figure out a safe track legal way to mount and run line..

I'm just going to piece together the nitrous kit, then a fuel system for it, and it's pointless to upgrade the brand new proven fuel system with out having a complete or close to complete nitrous setup ready in my opinion

Keep suggestions and advice coming please!
