asthetically, it looks ugly!
Hows that extra horizontal exhaust pushrod being supported?
Okay, I guess i can give em that..
new oil pump design.. I hope it deson't get stuck in low pressure mode..
New high capacity water pump... if its compatible with the ls1/6 engines, thats good news for the high hp guys..

The three-valve design adds complexity but uses the type of coments with which GM is very familiar, so reliability shouldn't be a problem"

Actually a lot of manufacturers are doing this. Covering they're engines with plastic to make the engine bay look classier.

Actually, I was talking about the rocker arrangement.. That extra pushrod and dispaced rocker looks totally out of place... Basically, in my mind I hear both, "Thats ingenious!" and "That looks like a total hack job!"

Looks goofy but if it works.... I'd much ratehr see a variable timing twin cam design than a single cam in the block with 3 valves, one of which connected by two pushrods. Seems to me the extra complexity of this design will be good for the C6 and future Chevy small block users but hard to adapt to for the performance aftermarket. I wonder how this extra vlave will affect swirl and flow characteristics at low rpm. Not to mention the placement of the sparkplug. The ideal spot would be right between the valves.

As far as prettiness/ugliness of an engine...I could care less...if it's making great power and my hood stays shut anyway what difference does it make?
