I spoke to a mathematician friend of mine and this was his answer:
" Assuming zero deck height, I calculate the swept volume of the piston to be 647.4 cc. Assuming this

thanks for the help, im not running zero deck height just the usualy skim of both heads and block. so i guess im around the 8:1 to 8.5:1 so my engine should be good for a turbo... |
