Some of you need a refresh over at the mustang build site... or just try 
These rims are an 18'' option on the 2010 GT for $495
And part of the 2010 v6 pony package (which is at $995)
They've been around for a long time now...

meh...i think ill be the only one in this thread and say i like the way it looks in the spy pics better. but those intake runners are nice 
. is it me or does it look like the valve covers have plastic over them?

Direct Acting Mechanical Bucket - IIRC instead of having followers like the MOD motor uses, the coyote's cams are postioned directly atop the valves and transfer the cam's motion to a bucket lifter over the valve. It allows a more compact valvetrain and reduced complextiy, the latter of which allows the engine to safely rev higher (possibly due to less mass as well, but that all depends on how the MOD's valvetrain was setup. the followers may have presented less mass at the valvestem???).

Sorry Branman!
For those that haven't seen in the 412hp thread. Thoughts? Engine looks great. I don't care for the font on the badge.

does anybody have a shot of the 4.6 3v at the same angle? It would be nice to make a size comparison. Also any idea on the weight?
I've heard unsubstantiated rumors of 500+ pounds, but being that the 4.6 3v was 420-440 lbs dressed, I'm filing it under B/S.

We get it.
I agree with you that a positive displacement supercharger nestled in the valley between the rows of cylinders looks badass, but the Mustang GT doesn't offer a factory-supercharged V8. Therefore, I'm glad Ford designed something tasteful yet aggressive to clean up the clutter that plagued the Mustang GT V8's of yesterday.

It's the DAMB lifters. Eh take up less space than roller finger followers and don't afraid of anything.

While eliminating roller followers might - but not necessarily - reduce the height of the cam tower, the 4V would now have a cam directly on top of both the intake & exhaust valve bank - which widens the cam tower - and if it was the same block as the 4.6 you would now be closer to the body.
Notice the difference in width of the head between the 4.6 3V and the 4.6 4V:
That's why the 3V SOHC was so ingenious (although you lose the ability for the new iVCT).

I don't know about that... if there actually is more room in the engine bay it may be due to the design of the 5.0 block (shorter stroke?). And rev limits on the 3V have more to do with composite rods - not lever roller followers vs direct cup followers on the 4V. I have not yet heard of a failure of the roller followers. As far as less mass, the 4V has more moving mass with twice the cams.

The less mass being referred to is the reciprocating mass the moves with the valve stem, and not the rotating mass of the cams. With a lower reciprocating mass, the valves can close more quickly without the need for a stiffer valve spring. This can allow the engine to spin faster before the valves 'float'.
So I'm curious of the different load factors attained by elminating roller followers but adding 1/3 more valve train and twice the cams.
