Newbie question., How do I tell a 2.0 from a 1.7 Options

[Doug73/2.0]

Saturday I'm looking at a local 73 with a 2.0. Just to be sure what should I look for to confirm that it is infact a 2.0 and not a 1.7. Given how many 914's I've looked at these past three months, seems a silly question, (IMG:style_emoticons/default/blink.gif) but all the others I stopped when I saw rust beyond my ability. I know the engine code should be a GB100 but where do you look on the engine for it.
Thanks for the advice.

Doug,

The obvious stuff also is the the 73 2.0 came with all of the goodies, IE-leather wheel, center con w-gauges, alloy's, chrome bumpers, padded roll bar and vinyl roll bar sail panels. My opinion is that it is relatively unlikely that a car would be a fake 2.0 and yet have all of the accessories...but, there could have always been an engine swap later on...if this is the case, look at all the stuff noted above.

-BTW, I am in boston and have a 73 2.0, so depending on when and were I could take a look at it with you if you want some help.
