(Edit - I believe the 5. Big Jug BV carb was also used on the 66-67 250/155 engine, but maybe rare since shortly after the 250cid came out, the BV was discontinued and in 1968 we got treated to the MV aka Satan's Carb instead).
Martin, as far as tags, I have not paid much attention - usually missing anyway. First hint is the throttle bore, then look down the venturi and try to guess it from there.
From that point I just use the jet I like (Holley jets work but you have to use about 4 numbers bigger) and drill the PVCR (power valve) to where I like it.
Still, some of the carbs just "run" better than others, best is to collect a few of the size you want and run your favorites.
