Just a FYI on the Dove TW intake, it flows over 500 cfm if you do any gasket matching. There are very few FE's that can use that airflow. The new HR 8V-F that Chris Whitney sells flows ~430cfm as cast, and that manifold should be able to support any FE requirement with a simple gasket match. They will flow 470-490cfm if worked on by someone who can flow them and balance the runners. They are good as cast. I have ported several and if I were building another 511/527/530 cubic inch HR, that would be my intake of choice. JMO, Joe-JDC
