well I stand corrected per a circle track article on a 2gc carb the 435 cfm version is the one Billy Nees refered to the 1 3/8 venturi carb, the 1 1/4 venturi carb I ran was rated at 390 cfm per the article in circle track, SMI wrote the atricle and said these carbs were actually flowed , and flowed more than there rating.the 435 version is rated at 500 cfm and circle track racers use it alot , the 390 version is used in rules limited situations it flowed 435 with alittle modifications to the boosters all legal in Stock Elim.....Just my 2 cents
