^^^Ya that's the thing. The JE will have more slap because of the lower silicon content. My JEs slap just a bit when it is really cold out, but when they are warm it goes away. The CP and Wiseco engines I have built ran very smoothly without any piston slap whatsoever. But they inherently arent as strong. As long as you don't detonate you should be just fine, but cross that line and any piston won't last long.

Stock cast pistons can handle over 500whp without breaking, but for how long? Any piston you pick you will likely be happy with.
