possible for single idf to run good?

[brianwheelies]

guys, i'm getting tired of the dual carb thing. i currently have two single idf manifolds, one has huge holes where the carbs mount to the manifold and the other has holes about the size of the bottom of the carb. also the first mentioned manifold has the two barrels totally separate of each other while the second one has a hole between the two tubes allowing some sort of balance between the two. is it possible to get a single to run decently and get half way decent gas mileage?

my setup is as follows
1600dp w/stock heads
dual 40idf's
1.25 rockers
svda w/compufire(idf's don't have enough vacuum to work properly with 2 carbs)
1 3/8 header and single quiet pack
