The 194 engine in the early-1960's Chevy II was the first of the late-design inline sixes. The 230 and 250 was made on the same casting. That chassis was designed to accommodate a dealer-installed small block V8 for the "Factory Experimental" drag race class that was popular back then. It was no accident that the motor mount position and type was identical to the 283 and 327.
