Casting numbers? Org 67 Ram air?

Where can I look up casting numbers to find out what I really have? I just aquired a 67 GTO conv. and I think it is a Ram air but the carb filter housing is gone.
Is there any where I can look up the VIN for info as well?

If your looking for info regarding what your car came from the factory with go here...[www.phs-online.com]
They have an option where you can have the info faxed to you.

If your looking for casting #s try this site...[www.yearone.com]
They have a great Engine ID section.

Good luck

Thanks!
