Not Ranked
Really, I wasn't trying to start a fight or anything, just a discussion about airflow. From the AFR website, the minimum flow head for the big block Chevy flows 321 cfm at .500 lift through the intake valve. The max flow for a small block Ford is 289 cfm at .500 lift. Not even close to the same. I fully understand why you can't get more flow in the small block head, but I can't quite fathom why people recommend smaller head flow numbers for a 427 small block. Just thought about some of the recommendations going around on the web ref. small block/high cube engines and wanted to throw it out for discussion.
