283 Question
I have a 1963 Impala Convert with a 283 Rochester 2 Barrel Carb. How many CFM's is the stock rochester carb? If you do the math you come up with 409 CFM> (283 cu in X 5000 RPM max=1,415,00 / 3456 = 409 CFM)
I can find a 4 barrel Holley # 08007 with 390 CFM and a 2 barrel Holley 07448 with 350 CFM also might be able to use a Holley 2 barrel 04412c with 500 CFM My other question is what happens if I use the 500 cfm carb on my stock 283 ? Will it be over carb ed and maybe bog or use to much gas.
I 'am not looking for more power just a better crusing carb for this car.
Thanks Dan
