I was looking at a 70's setup and this appears to be very similar. It's a 73 built in September 72 - so they should be flattops, shouldn't they?

Many of them were dealer retroed to roundtops.

Not if you want to drive the car!

Can't tell from the pictures which manifolds it has, but the fuel rail is the shorter one that came on the '73-74s with flat tops. So I agree with Stephen's assessment, it is a flattop car that has been converted to roundtops.

I'm just going by memory, but some of the hoses look misplaced - such as the AB valve connection to the air cleaner. Also, are those dampers the type that came on flat top carbs?

Thanks guys - I knew it wasn't a stock setup. Needed to confirm. Is there a way to tell if these are the early or later type roundtops from these pictures?

They look like 3 screw units, which I suppose could be called "later".

Count the number of screws that hold the domed part to the body. The early cars had 4 screws, the later had 3. For pictures check the "spotters guide" here:

Wonder where that came from? Flat Tops didn't start until Aug of 1972 here in the US... when the 1973 Model Year cars started production.

FWIW,

A couple of pictures I got today.
