Just looking to see what people think on this. Have a 70 Dart swinger with a 318 that is bone stock except for dual exhaust and a 1970 340 4 barrel intake. How much carb do you think that engine could take without overfueling?
2nd I agree with everyone around 600 cfm give or take 50 for your car.
3rd generally for a small block 400 + hp = 750 and 350 - hp = 650 . Now in between can go either way. Now under 200 hp you can make an argument for a 550. And for some race only and or big inch 850 +.
