nitrous on my 355

[Project86]

Wanting a bit more power from my sbc.
Right now it's just a .40 350. New internals but all stock.
Stock heads, springs etc.
Running a xe268 cam. Performer intake. Holley 650
Th350 trans with a 2000 stall
3.08 gears

Can't remember total timing off the top of my head but I'm wanting to put a littlle juice to it and have a little fun
Engine runs great. Good fuel pressure. No issues.

Want to get a single plane intake and eventually change over to electric fuel pump setup
as far as nitrous goes. What kit is best? Spray bar or a perimeter plate?
Wanting maybe 100/150 shot. Even less is fine.
