hehe my sentiments exactly...

ANYways...

The KA crank is NOT knife edged...there was a pic on fresh alloy a while ago of the KA crank.

400 hp to switch out the bottom end on an SR is a conservative estimate - I've seen estimates as high as 500 and 550 hp before the bottom end of the SR needs work.  That being said, the SR needs headwork before the KA, at about the same time the KA needs bottom end work - but for me at least (and this is, of course, not about one engine being better than the other, but about individual choices), I'd rather mess with the head than the bottom end - you don't have to lift the engine out, and when you work the head you can get power from cams and revs from lightening/strengthening valvetrain components as well...

And whether you need to switch out the components on the KA or not, the fact is that you have to pull the engine and mess with the bottom end, which you don't have to do until higher on the SR.
