Be more specific on squish.....decking the block? or milling heads?



Here is a pretty good read... http://www.moparts.org/Tech/Archive/motor/38.html

I prefer squish, quench is the same thing..

You will need to deck the block to zero deck, or .005 in the hole is common. The 915's are closed chambered heads, CCH, makes it easier to obtain squish. It can be done with open chambers but much harder to do, and pop up, or quench dome pistons are going to be a necessity
