good advise, otherwise should work fine. Actually the Edelbrock 600 should work fine for that application. Im not usually a big fan of Edelbrock carbs, but they do a good job in draw through applications.
Id still recomend an MSD Boost controller. 305s are timing sensitive anyway due to the small bores & shrouded valves, add a blowers boost & your just making timing issues worse without a controller. John
