Looks like I need to build an air pan for a cowl type hood. Running two dominators. Carb builder wasnt a fan of no front facing scoop, but the nmca shootout rules for 2011 were just released prohibiting the scoop. Better to pull from windshield or from front of engine compartment? Thanks.

this has been dicussed before.seems everybody has a differant experience and/or result.i have a 4.5" cowl on a chevelle,n/a 975hp.i made an air pan and sealed it up tight so the only air it got was from the cowl.i took it off and it picked up 2mph and .10-put it back on and it slowed.a friend has the same type car/setup and his picked up.also have heard of people slowing with forwad facing scoops-was told it was "air stacking"-no idea what that was.i'm gonna try pulling the air from the front this year,we'll see .....:).......good luck

In my limited research, Ive been told the dual carb set up will be worse off than a single. Guess I should steer toward the pro stock truck set up. Havent seen too many set up this way.

alot of people forget to seal the cowl panel cowl induction don't work if the air goes down the cowl not into the hood but thats more on the older cars meet a guy with a nova ducted tape the cowl and picked up redneck enginering ha.
