Speed Density is a tricky system to work worth.
You will need an adjustable fuel pressure regulator.........You have to compensate the extra air flow by adding extra fuel.
Speed Density is not very "cam" friendly most people just use 1.7 roller rockers to increase the lift of the stock cam.
Feel free to PM me with any questions you may have.
