318 compression calculator with KB167
Hi all,
I have been using this
compression ratio calculator and would like to know that I am entering the numbers correctly.
The KB167 pistons say +5cc but I have read that they should be entered as -5 for dished pistons?
Please see image attached. I am aiming for around 10:1.
This is assuming a piston to deck height of .012 and a .030 over bore.
Does this look correct or should I have the piston cc's as a positive?
Thank you.
