Nitrous Kit
 

I have an NOS Sniper kit that I never got around to using. Still in the box, only the plate has been out for set up and then it was put back in the box. Only thing missing from the kit is the carb studs, which can be picked up at any speed shop or just grab bolts from the local hardware store.

Kit is for Holley/Carter/Edelbrock square bore carbs. Catalogs sell it for 375-400bucks, I will take $250 OBO just to get it out of my house.
