65 factory carb cfm's ?

[sigshooter]

I built this 230 engine years ago. It has been bored, 307 pistons ( makes it a flat top engine) clevite cam ( nothing radical, just like an RV cam ) ported on the head ( just to clean everything up). I want to keep the stock look, but squeeze some power out of it. I ran a GM 2 barrel and then a Ford 2 barrel both on the stock intake with an adapter plate, ran good but wanna go with a stock look. I was wondering what the stock CFM carbs were and hoping to get enough out of the 292 carb for the appearance I want. The truck is torn down for the winter so I cant just try carbs until I get the desired look and performance. I will tune the 1 bbl carb until I squeeze enough CFM and plan on swapping to the bigger 292 exhaust manifold. Any body got any performance ideas while retaining a stock appearance? I currently have later HEI but am considering a point distributor with a pickup module. Engine has maybe 5,000 miles on it since I built it 15 years ago. It has mostly just been sitting until life slowed down so I could get back to it.
