Sorry if I led you guys down the wrong path. I've been contemplating a 360 with a 4" crank and I'm trying to understand as much as I can before buying any parts.
I have read about guys dealing with spark knock and how quench helps reduce the risk of it. I am interested in learning from experienced engine builders so I can make as few mistakes as possible. I've read through a few books including "How to rebuild your small block Mopar". Those books don't delve into aluminum heads and strokers though and that is where I need the help.
The reason I mentioned the .020 number for pistons in the hole was that I read that number in a thread somewhere. The .039 is a common thickness for the Fel Pro head gasket.
I understand that quench is important, I just was curious about the approximate distance where it becomes a NON issue.
Thanks to all. I hope that you don't feel that your time was wasted. I just want to learn this stuff!
