<,The casting process is alive and well -- Rover uses it on an old GM aluminum block V8 (the Buick one from 1960 or so) and Benz uses it in all their engines these days, so there is nothing wrong with the technology. GM just failed to do the design correctly.>>
Actually, what is shared to this day by Mercedes (and Porsche) from the poor old Vega is the Reynolds aluminum alloy, not the "casting" process which is entirely different, particularly at Porsche. As to Rover (BMW), they have abandoned the underpowered old GM designed V-8 for BMW power. RLE/Seattle
