Chevrolet Impala (1960)

#4
Let me subjoin a section: in the late 50s, the V-eight 348 Turbo Thrust (never mind turbo) was the most powerful Chevrolet engine. The cast-iron init was distinguished for the original geometry of combustion chambers: the lower face of the cylinder heads was flat while the banks upper deck was cut aslant as regards the cylinder axis.
At that, pistons had a "gabled roof" top: this formed a wedge-shaped combustion chamber within the cylinder. In this way, the combustion chamber turned out to be fully machined - a worth-while outcome in default of NC machine tools.
