depends on the blower and whether or not the rest of the engine is stock or modified, if you check out blowers on sites like jegs.com they usually specify HP gain
buy a blower intake (prefer 6-71). then buy 6-71 blower, and accesories. change your stock intake put on blower and check pulley ratio to reach 500 horse from the horse your now running stock. Might help to change to alum. heads but if you dont run to much boost you will be fine
