Ha ha,,,,six pack in the trunk, I like that!
Perhaps the reference to 6 Weber carbs is the appearance of three single "double throat" Weber carbs? It's easy to mistake them for "two" carbs if you don't know what your looking at.
I recall tuning such Weber Carbs on a "real" Ferrari "back in the day" for a customer. I used a vacuum gauge on each carb to synchonize them. Interestingly enough it WAS a lot like setting up each "barrel" almost like it was in fact a "single" carb.
Not to mention the FOUR sets of points divided between the TWO distributors. And don't even get me started on the valve adjustment,
The best part? The test drive of course! Ahhh, those were the days, my Ferris Bueler days.
