Input (grade 6): Other 60 Â V6 engines are the Chrysler 3.3 V6 engine, the Nissan VQ engine, the Alfa Romeo V6 engine, and later versions of the Mercedes-Benz V6 engine.
Output (grade 5): It takes little work to change an V8 into a V6 engine. The problem is these engines are wider and have more vibration than a 60 Â V6.
