I have a complete nitrous setup for a six pack. I used it years ago on my race 440. Everything is there. Lines, solenoids, plates, jets, extra 4bbl plate, two bottles, brackets, etc. Just been setting since I sold the car. An NOS brand system sells for about $500.00 through Summit and is for a 4bbl only. It only includes one bottle also. My setup would cost over $1000.00 to duplicate. I think $500.00 is more than fair for my setup. Pickup only. I am west of Nashville Tennessee.
