Carb and intake for cowl hood

[1st_chevelle]

Well there comes a time in one's life when he needs a new carb and intake. That time is now. Or even sooner if I can find some tnt and send that damn rochester carb to the moon. I got a 468BB stuck with one of those and it's killing my performance. It feels like it's barely making 150HP when I know it's capable of at least 400HP and more. Anybody have a good combo that works with a cowl hood or at least point me in the right direction? Thanks for your time and consideration.
