318 4 bbl and intake upgrade

The benefit I see from going to a 4bbl intake is not the extra carb flow so much, it is the improved runner design/shape that comes with the 4 bbl intakes. It is a low performance engine & if we are generous & assume it makes peak hp @ 5000 rpm with 80% VE, then a 318 only draws about 400 cfm. So a 500 4bbl like the Edel AFB/AVS would be ideal.
