Alright looked around a little bit on here but couldn't really find anything. Found a set of barely used forged keith black pistons for sale. He told me the part number was Kb 718. In his discription he said they would handle 900hp and up to a 200shot of spray. My question is, are they actuallly this strong? and has anyone every really heard of them being used? I know when i used to race dirt track people said to stay away from them, but i'm pretty sure they meant the hyper ones. Any input is appreciated.

Thanks Chris
