Inliners International Forums General Discussion Engines Stock 292 carb versus 250

Does anyone know if the factory single barrell Rochester carbs on the 250 and the 292 are different in cfm rating?If so do you know how much bigger the 292 carb is.Thanks..............Gerald

There are several different throat sizes for the Model B Rochester. The one I had on my 292 was 1 3/4 inches. I also have 1 1 5/8 in my collection. What cfm might be I have no idea I've never seen the cfm given for the Rochesters.
