Our '60s GM 194 inline-six came fully dressed with the clutch and bellhousing. We managed to score a GM SM420 transmission for $50 from a friend. To match the SM420's coarse-spline input we swapped the old T-90 conversion clutch disk that was in there for a new NAPA 11-inch unit from an early '60s GM truck. The tranny and engine went together just like at the factory. The 194 utilizes the same bellhousing bolt pattern and starter as GM small- and big-blocks. So if a free and running V-8 ever strolls our way, it won't be a difficult swap. Although, the quirky looks of the inline-six are growing on us.
