Dad, a picture is worth a thousand words Holley on modified stock intake
My other truck is a 37 Chevy with a modified 261,hotter cam, Fenton headers, 390 Holley on a Clifford intake.I did a lot of experimentation with carbs,seems these engines don't need a lot of carburetion for most tuning applications.A small 4 bbl will work on a 235 ,just make sure the secondary opening rate is delayed as long as possible.More carb may feel better, but the stop watch says differently.
