i want to increase my hp to 650+ on street/strip. i want to know what cam should i choose and what do i need and i want to use nitrous oxide on my engine.

any suggestions?
Call one of the cam makers tell them what you want to do and they can help you out.I would look at a mech. roller cam ground on a wide lobe seperation for the N2o.Also to get 650 + h.p. you will have to look at some really good heads.You did'nt say if that 650+ h.p was with the bottle or not.
