Anyone using a Holley Street Avenger Model 2300 [350 cfm] 0-80350 on a Ford 200-6L? Engine is modified, healthy cam, lot of port work, some compression, header, big exhaust, idle vacuum around 12 if I remember right, ing 16° initial and 36°total in by 2500 or so. I have been running a Holley 350 cfm that I conjured up that worked quite well, not so well now so thinking of the new Holley with more performance knowledge built in.
