Holley sale

I am interested in the 3- 4160's.
Could you tell me what shipping would be to Henderson NV 89002?
Also could you give me the actuall part numbers off the carbs so I can check the application. I'm looking for something to use on my son's 72' Murcury Montego w/ 302 and my 79 Chrysler w/ 318.
Thank you.
