    im upgrading engines now and was thinking i will definitely need more carb now with the other engine i have, i was told before if you take a 750 double pumper and put a 850 baseplate youd get a 950 cfm carb or something like that.. now im wondering if its possible to upgrade either the baseplate or body of my quickfuel 780 carb to flow around 800-950 cfm.. i know there are tons of tricks outthere i need to discover. thanks
