[quote=B1MAXX]the down fill is for when a piston has any part of itself above deck. dome or the whole thing or both, so that we can measure it. To add the deck height back in to the equation would be double dippin.
Just to be clear, not everyone does it this way.
I, for one, don't.
I use the fill down method for determining dome volume
only.
This is what the OP did as well.
Once I have that value, I can plug it in to the calculation and see where I'm at, and then easily make adjustments to chamber volume, deck clearance, etc if I need to change the cr to meet a target. [/quot
good to know im not the only one thinking the same way.....thx Dwayne for clarifying that.
