i always thought it would be neat to mount 8 motorcycle carbs on individual runners like the Mopar ram induction photo shown above. Mount a fuel cell at the top of the cowl to feed them by gravity. Refill the fuel cell with a float mounted inside the cell that would activate an electric fuel pump to refill the cell from the main fuel tank supply and then shut off when the cell was full. Run all the carb cables together at one central point and attach your foot throttle cable or rod to the whole mess.

I'm thinkin' you could synchronize the carbs with a small twist drill to insert between the throttle drum and the bore of the venturi.
