I know if I were deciding on what heads to use on my hemi, to put in my 4175lb strictly street car with 3.54’s and OD unit......... really big flow numbers would be right at the top of my list of “must haves”.
You neeeeeeeeeeed 400+cfm of flow available when you’re racing along at 2100rpm.
Really? Are you being serious? I value your opinion very much. I know that at cruising speed the air flow does’nt matter. But last year at our “Moparts” Mike Bucle asked me to race his HEMI Coronet just for fun. I would like to take him up on it next year!
