and the single plane will perform even better with a spacer but don't believe it helps dual plane as much
blown and injected is the ONLY way to go
I would say single plane in most applications. On a low rpm motor I would run a dual....

yes that is what I would have expected too. but... I lost Rpm with the single plane with 2" spacers. For my next trick im going to remove the spacers. The manifold has a divider. between the left and right sides of the manifold (no its not a dual plane).Open spacers negate the divider. By removing them I may improve the vacume by only pulling from 1/2 the carb per side. I guess its worth a try.
