Going to overhead cams would probably piss SBC lovers off to no end.
Dear GOD MAN you did not actually think I was talking about multiple pushrods!

Hell yes I am talking about DOHC. Look how good the coyote V8 is in the mustang. I would love to see a variable timing 4 valve DOHC V8 in the vette at about 4.5 liters making the same HP as the 2012 Vette does with far more displacement.
