An acquaintance of mine does does a lot of NOS work. We have discussed doing this to my Caddy 261. He has set up several cars and says the trick is to keep your A/F ratio correct. NOS is a gas that has a high oxygen content. When you release it in the intake you need to add more fuel too. NOS works great and does not require any mods to the bottom end. What usually happens with the kits is that most people buy them and don't check the ratios. They usually end up too lean and melting things. Keep us up to date!!!
