Help please on engine size?

Hi there and sorry that my first post is a question rather than an introduction.

I am selling a 1972 type 3 notch back, I have been asked what the engine size is?
Can anyone tell me where I look to find this?
The car is here, http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=130275743976&ssPageName=ADME:X:AAQ:AU:1123
It has 2 carbies if that helps with engine size id?

Thanks for any help.

If its the original engine it would be a 1600 twin port
engine with twin solex carburetors...
