I have nitrous on my 57 chev but have never used it as I have been
told so many stories I don't know what to believe, but since I do have
it I am dieing to give it a try. Could someone out there tell me if someone
makes a box that will turn it on at different entervials. I already have it
plumbed to the carb using a crossfire. My ignition is msd dist 6al box
with a delay. thanks rdobbs
