4 valves per cylinder and 4 camshafts and VVT. Yeah I'd say its more advanced. But theres alot to say for simplicity. 2 valves per cylinder and 1 camshaft. Thats why we go with more liters.LOL. Take a look at the fastest vehicles to run the 1/4... HEMI. And they are big and simple. But for the street its a good choice. Go with Ford and their high tech or go with Dodge and their sledge hammer approch. I'm more of a knucle dragger and I like my brute force.
