Nitrous ????? Plug and timing settings?????

[john_86stang]

See my sig below, Mostly stock which plugs should I be using in my 86 GT. Right now I have Autolite 2545's in it, which is what the local parts store says is called for it. Is that the correct plug for my stock setup. Have the gap set at .050". Also I'm installing a NX system this week. Which plugs should I use with it? and what about timing? I plan on starting with a 100 shot then a 150 shot. Also right now I'm at 37psi(vacuum off) on my AFPR, NX says their system is set up for 40psi. Should I turn it up at first then read plugs and go from there? Sorry so many questions. You guys are great!!!
Thanks John
