Its VERY hard to discount the opinion of Darin Morgan, one of the top cylinder head guys in the world!
But what I see so far is TWO V-head engines from the same source fall short of expectations!
1) Ed Page 535
2) The 755 HP street engine that supposedly *shoulda* made 900 HP if it did not float the valves at 6600 RPM's
So 0 for 2...

Someone needs to start getting it done and STOP making excuses!
