[QUOTE="Quadcammer, post: 2364659, member: 6813"] ROTFL. the dohc is not far better. Its got twice as many valves, 4 times as many cams, and 2 long ass chains driving the valvetrain. Thats a lot more complexity. In stock form the headflow isn't terribly impressive either. 245 I @.5 valve lift/ 175 E @.5 isn't great. Compared to a stocker e7 sure its impressive, but considering heads like the afr 185s, 205s, and 225s, its nothing that can't be reproduced on an ohv motor. look at the ls7, 360cfm Intake on an OHV motor. The cobra R was pretty much a race motor with custom parts such as that intake and the heads (which are now more common). the ohv windsor motors are cheaper, lighter, smaller, and less complex. take a 351w block, bore it out a bit, add some stroke and you are looking at 392 cubes. add some 225 heads, a decent rotating assembly and you are making some serious power. add some boost/nitrous and the power can be insane.
