How much extra clearance does this scoop provide? I'm running an Edelbrock intake and my carb hits the stock hood now... and I still need room for the filter.

• might be a dumb question but is rain a problem with this hood on a daily driver? general
• Are the vents cut out on the driver and passenger side for the bent boxes? general
• Are there provisions for or can windshield washer nozzles be installed??? install
