I currently have a Holly street avenger 770 with electric choke and vacuum secondary's. I have it tuned well and have no bog or stumble and was wondering if switching to a double pumper would be worth the $500. I was looking at the

"HOT ROD" SERIES QFT

750 CFM DOUBLE PUMPER

ELECTRIC CHOKE CARBURETOR

So is it worth it and what should I expect to gain in performance

The engine is a 408 stroker with an estimated 500hp.
