carburator help

I appreciate the responses. So it looks like everyone is recommending some form of a double pumper. I have one sitting in the garage (850 cfm I think) but I don't know the number off hand. I was hesitant about using it only because of all that fuel dumping in down low. I thought maybe I should try one of my 850 thermoquads but thought I would starve the engine down low with those small primaries.

The other common thing from you all is 850cfm is the size. I wasn't sure I needed one that big.

Keep the suggestions coming! Thanks!
