More compression is good. GM also broke ground in the SUV segment by using dual overhead cams with roller-followers to control the four valves per cylinder. Dual forced pin oiling on most applications, Lateral gas porting on higher compression ratios. Sutter and his team devised a dual-frequency harmonic damper that attached directly to the front of the crank to counteract the effect. The beam also helped reduce vibration and noise, while reducing the chances for an oil leak. The same aluminum and heat-treating were also used for the cylinder head. The design was chosen thanks to the large volume of air four valves can move, while the roller-followers provided a smoother operation with less friction than conventional lifters, adding to the engines efficiency. Due to the manufacturing process, they are stronger and therefore allow reduced wall cross-sections and lower piston weight. Prior to assembly, the con rods have been checked to see that their bores are on parallel axes (to ensure that there has been no bending or twisting), and if necessary, they have been replaced. Pistons with cooled ring carriers For these pistons, ring carriers and cooling channels are combined into one system in a special production process. Up to 3,000 tons of force forges aluminum slugs into the basic piston form which creates a grain flow pattern in the structure providing excellent strength, ductility and improved heat dissipation. The rest of the Firebird is as nice as the engine compartment, which explains why it took three and a half years to complete.
