Ive been wondering what does a nitrous cam differ from a N/A cam? or is there any? i plan to get a cam pretty soon for my truck, i am currently not spraying, but if my goals are not achieved i plan to spray it to get me their. ive seen many cams in classifieds that say its a nitrous cam but i have no idea whats different. so you guys that spay please shed some light because im clueless.
