Features like coolant passages, oil galleries, and oil drain-back passages were cast directly from the foam, eliminating the need to drill into a pre-formed cast block. Because of the high temperatures at the piston top and the ring belt, intensive cooling is provided with oil circulating through the cooling channel. GM also broke ground in the SUV segment by using dual overhead cams with roller-followers to control the four valves per cylinder. Molten aluminum is then poured in, filling the voids left by the melting foam. The Chevrolet small-block V-8, for example, began life in the 1950s and soon became the standard for high horsepower in a small package a legacy that continues into todays fifth-generation GM V-8s. For model year 2004, the Vortec 4200 was introduced in the all-new Buick Rainier and Isuzu Ascender. However, it was logistics that squashed that from happening.
