Big Boys compression calculator questionpp
This may be a stupid question, but here goes:
Trying to use the Big Boyz calculator to determine static and dynamic compression. I don't have all the specifics on the pistons and deck height. Pistons re standard bore 95" rated at 9.4cr. How do I plug that into the calculator? I keep greeting static compression less than 9.4. Heads were decked .020, but unfortunately builder did not cc heads. He told me the heads he gets new from HD are pretty consistent 85cc and told me with decking, heads should cc around 83.7cc. None of this matches up with what I am reading - .010 milling should equal around 1.6 cc. Can someone help explain some of this?
