Did another search and found a bit of info. Looks like mixed results, probably not the best carb for the application. Will keep looking for some suitable 1BBL carbs (not Rochester B) unless I give in first and buy the C/W's from Tom Langdon.
Did find a place selling Holley 847 1BBL carbs. They are supposed to be great carbs, anybody try running 2 of them on a 235 or 261?
