>> Interested in experiences 'setting up' larger CFM carbs on small sixes especially with forced induction.
Conventional wisdom says adding a blow through setup doesn't need a much bigger carburetor , just more fuel under boost. Available off-shelf blow throughs' (CCS, QF.BG,...) are typically big 4Bbl's @ 650cfm and up and not suitable for small six blo-thru's (although CI head used 4bbl manifold NA).
My current forced induction project is Ford 250 six with Holley 2Bbl 2300- 7448 series 350 CFM carbs' modified for blow through operation. The 350cfm 2300 are popular performance carbs for modification and parts are readily available. The 2300-4412 is the 500cfm version of the 2Bbl I plan on next modifying for Blow-Through.
