As long as we're being impractical, why not go with a setup that's been proved to work well in the past? The 235 engine is almost exactly 3.8 liters, a displacement it shares with 1950's Jaguar engines. How about adapting a set of triple side-draft S-U carbs from an early Jag XKE and really have some eye candy? With a 3-carb setup and the firing order of an inline six, each carb only has to deal with supplying mixture to one cylinder at a time. That makes the carbs relatively easy to tune and synchronize, and side draft carbs don't have some of the clearance problems a 3-downdraft setup does.
