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

Is messing with the boosters legal?
Is that considered a jetting change?

Shouldn't be, but 2bl guys around here were doing that in the '70s. Seemed to go through tech OK. Pretty dramatic improvement in air flow and track times. I couldn't believe they were getting away with it.

Seems like I remember from the old days that a 2 Brl.Brl. Flow Bench was at a higher level of vac. than a 4 Brl. Does anyone remember the difference? Would 400 CFM on 2 Brl. bench be about 300 CFM on a 4 Brl Bence setting?

Frank bought the car from a guy in So. Windsor, Ct. I'm pretty sure he then put the 4 bbl on it in the late 80's. Might have gotten it from Eddie Bednaz, although I know I worked on the carb too.
