bigger carbs for better mpg ???!!!

i have a buddy here in town that has a old bronco with a huge small block in it, and he was saying that whenever he had a big block motor that he could never get a quadrajet to give him good mpg compared to a eddy or afb carb. he was then talking about how with the smaller primaries the qjets choked the motors and he always had to step in it harder to get up to cruising mode.

and also to add, he has a qjet on his 305 monte carlo and gets 20 mpg intown, and 25-27 highway.

and a qjet on his motorhome with a 350 and he gets 10 ish which he said is good ( i know nothing about motor homes )

is this just a tuning issue on his part or are there just certain motors that like certain carbs ? i know everyone says how great a qjet is so im slightly hesitant to lean to one side or another
