[47 Roadmaster coupe 320" dual carb main jets]

Carbs are Stromberg 2 barrels. Haven’t really check the carbs for #. Thinking of just getting a wide band o2 meter and fixing it . California gas burns lean and a wide band will get accurate results . Problem is I have to weld an o2 bung on the exhaust . Then throw on a 12v battery to run it temporarily .

Somebody converted this car to dual carbs.They did a very nice job cosmetically but it seems the car is running lean at cruise.question is what main jets were standard size?
