The maker uses a stainless steel material. This engine also uses one of the best materials to build exhaust gaskets. Even more, this design also lowers the emission level. Thanks to this design, the combustion efficiency increases multiple folds. It increases the effectiveness of the intake and exhaust strokes process. Other than increased displacement and VCT, this design also affects the engine’s breathing. All of these are necessary to produce the best performance from this engine.Īs we mentioned earlier, this engine uses hemispherical combustion chambers.


Some of the models also use the Aisin six-speed automatic transmissions. They are the 66RFE six-speed automatic transmission or the G56 six speeds manual. The car or truck manufacturer combines a 6.4 HEMI engine with the three transmissions.
