He can have anything done. As for the Knife edging, it lightens the rotational weight improving rev-up time, meaning that there is less resistance against the engine. Quicker rev-up makes for quicker spool up, resulting in a wider powerband. It also makes for less resistance against the oil that the counter weights dip into and makes for less aeration of the oil in the pan. Inline and boxer engines can have FULL knife edged cranks which results in even better performance since more can be removed.
The Tig welded weight is, in my best guess, a precautionary measure so that the weight does not back out. The weight they add is to balance the crank at high speeds. My particular engine will have a redline of 9,000 RPM.
Here is a link to a specific package that he offers for the 350Z engine. Notice the 1200 WHP capability on it.
