Maybe he could fit this one in?
Chrysler's infamous W design tank engine mounted five 6cyl truck engines on a common output. One engine vertical, 2 flat out the sides and 2 at 45 degrees in between. 5 different intake manifolds were designed to hold the carbs upright. Tuning was a nightmare. 5 distributors to time. Try finding a miss on 30 cylinders.
