Bill - Have to dissagree. When the pistons are set up as the 
manufacturer recommends (something some folks make a cottage industry of 
ignoring) the KB's are good for a great deal more than you stated.  
"Ray's pistons" are Aires forged, which I have no doubt are better than 
my Keith Blacks - at more than twice the cost. They can be ordered 
directly from Aires for about the same price, but if Ray has had some 
made and is keeping them "on the shelf" for immediate availability then 
buy them from him as reward for doing that.

Why do I suspect that the Aires forged are better than my KB's? Just a 
logical assumption, knowing how they are made and what they are - The 
same way that I suspect that my KB's are better than Fed Mogul forged. 
Do most customers need to spend the extra money for the Airies? I 
wouldn't think so, as our KB's are being used successfully in a number 
of VERY high stress applications. With the forged and the KB's being 
pretty close to the same price the KB's make the most sense. A third run 
of the KB's is expected  this Spring. Lon
