downdraft carb

[German guy]

Any consensus out there on the best down draft carb and manifold that does NOT require a fuel pump? Looking to increase power after having added a Zipper Dist. My '30 Tudor has a recently rebuilt engine with stock head and no leaks. I plan to add a Snyder's cast iron header. Lots of hills where I live and I need more power without turning the under-hood view into a hot rod wannabe.
