And a dohc 5.0 engine requires 3 extra cams and twice as many valves to make as much power as an lsx or hemi. I'm not sure I'm understanding your point. I personally prefer more power and torque down low. Having to rev an engine up to 7k to get any power and enjoyment out of it just sucks ass to me.
If you prefer pushrod buy a hemi or ls motor. I have had all three and they each of their highlights...for street racing a boosted coyote is my choice.
