How about posting the combo here, and getting feedback on it. To get accurate numbers from DD5, You need head valve sizes+ flow numbers at .100" increments min., or even better .050". You need detailed cam lobe profile & specs, and realized rocker ratio/actual valve lift. Type of head, squish/no squish, whether You're using a dome or closed chamber to achieve it.
Actual SCR, Carb CFM @??"Hg depression.
A member who is already running Your proposed combo is the best ballpark You're going to get. Peace
