I had the dual Spal exactly set up as you've shown and my car would still hit 210 at idle with the a/c on a 100+ degree day. With no changes but the fan swap it wouldn't break 190. That tells me the Mark VIII definitely has more airflow.

agreed, mark wests 509 camaro at pigeon forge had twin 11 inch spals and it would enot go below 210, vinnys car had twin 13 inch spals on a junk be cool radiator and it would run 190 with short times at 200 till the fans caught up.
mark viii for me from now on
