Merc v8 flathead intake / carb ?

Can anyone Id this intake/carb what it would have been used on? Just guessing on the flathead , I don't know too much on the early Ford/Mercury stuff. I've never seen a carb anything like this before. Is there anything special about it? Could another type carb be used on this intake? Probably never use this anyway, but the carb looks very interesting.

 

Looks like a Y Block intake. The carb is a Holley "teapot". They are junk.

 

el-correcto! probably 54-55-57 merc.

 

looks like merc/ or y block ford..

 

Ford y block I ran one in the 60s and never had any problums with it.

 

Thanks I was thinking flathead for a sec and than I remembered that intake is very narrow compared to this one.
