To spray or not to spray

i jsut want to run max 150 shot but most likely 100shot and only at the track so i wont spend that much... and getting a holley blue pump is fine with me... i just dont know how to hook it up so i guess what i will do is get my motor done run my best have piston ring gap set to nitrous spec and then when i run my best time all motor. go nitrous for a lil more umph
