Summit Racing Thermoquad

what gets me is when you look up the details on summits site they say there square bore carbs.

Funny you mention that.....I was looking at these at Summit and they mention "square bore" AND "spreadbore". These sure look like repop Thermoquads, don't they? But only 625 CFM...? Has anyone seen these up close or have any knowledge of them?
