In-Line Autolite carb: were they legal in Trans am?

[Historybuff]

i was reading a site about in-line carbs and it reminded me that every once in a while I see a small block with a single or even two four barrel Autolite carbs and i was wondering if they were ever run on the Boss 302s in Trans am? I know they wre developed for Trans am and offered at Ford dealers as over the counter speed parts but I can't remember seeing them on the Boss 302s when Trans Am cars race at Monterey? Also I read Parnelli Jones tested a 6-barrel Autoline Inline but he rejected it for the Trans am. And I remember when Solo Automotive owner had a 427 Cobra he ran a single inline four barrel so they must have made them for big blocks but surely too late for the 427 Cobra when it was originally racing.

It seems to me the inline four barrel was the last hurrah of the carburetor before everyone went to fuel injection
