Interesting...for some reason i didn't realize it was a DOHC setup that was reaching that much power. I REALLY want it to be a 6 speed though guys. Thats the thing i really didn't like about the current lightnings. I love them except i think automatics are boring and less reliable
I would think cost wise they would use the 3 valve heads because you'll get about near the same power in the end with less moving parts and a considerably cheaper cost / head.
