Okay time for me to chime in with my 2cent. First off I have ran the carbs in Both directions ( street as well as Track) With vary little to No difference In over all performance. Esp. on the street. Now just a touch more food for thought. The carb does
not send the fuel anywhere other then into the intake. Each cyl.
Then Pulls the fuel to it's self. So with that being said The cyl. have no clue as to which way the carb is mount Left, Right, right side-up Or up-side down. Even when I had my dual 4b intake
I tired the carbs both ways and seen Vary little difference in the plugs. But to Keep the linkage simple I kept them Inline.
About the only way I see that you may see a difference in to which way the carb sit's is if you're going to put a divider in the intake.
God doesn't like ugly.
