Seems to be a common thing with Yank engines. When my mate used to run hotrods and funny cars we would always free up extra power from the engine by adding oil scrapers - rounding off cranks etc. The sloppier the engine the more power you can gain. Don't get me wrong I LOVE Yank engines but they aren't exactly overstressed until you play around with them.
With most highly tuned European engines there are usually much smaller gains to be made although there is always room for some improvement.
Google let you down this time..
The chief designer for the Verado series is a fellow by the name of Claus Bruestle. Herr Bruestle formerly worked for Porsche, where he was head of the design team for the Porsche - Cayenne V-8 engine.
And I am sure any number of your mates that drive Porshe's will tell you they are not known for being sloppy.
And before you start ranting that the Cayenne is not a real Porshe or whatever your going to say the one great thing about that somewhat flawed car is its engine, its a real peach.
