Back when we used to modify Holleys it wasn't uncommon to see a 15 or 20 HP gain. What's that going to equate to on your combination? It normally boils down to a fee reasons to get a carburetor modified. 1) You've changed combinations, and need more carburetor, and don't want to spend the money for a new one 2) There is a problem with the carburetor you currently have, and would like to make it better. 3) You're trying to get every last little bit of power possible.
