While all that jetting is fine for a starting point but remember the factory cars equipped with the vanke intake had larger carbs than factory street hemi.
Agreed, but when you get confirmed info from a reputable member who says this;
"I used this as a starting point with my sock 625 cfm carbs and vanke modded intake, and it worked pretty good."
It gives you a good indication that dual 625's can be made to work : )
