65 factory carb cfm's ?

[sigshooter]

I have a 65 1/2 ton 230 cid and a 64 1/2 ton 292 cid. does anyone know what the factory cfm's were for the rochester 1 bbls used on these engines? I was thinking of putting the 292 carb on my 230. I have tore both carbs down and the jet size is 57 on the 230 and 59 on the 292. I also have a 500 cfm holley 2bbl and the jet size is 73 on it..... trying to determine what carb will be best.

Thanks
