Hey Billy,
Our standard size 317 chambers end up at 74cc unless additional milling was done by us. To get to 68cc you should mill them .036" which will put you in your desired compression window. Feel free to call me at the shop if you have any questions.

I spoke with Richard at WCCH this week, AWESOME customer service as always
I can never say enough about how great he is to deal with, I can't wait to get my trans swapped so I can start on my LQ9 and get these great looking WCCH StageII's bolted on ![Burnout](https://www.performancetrucks.net/forums/images/smilies/LS1Tech/gr_burnout.gif)

What kind of HP/TQ gains are expected with increasing the compression ratio a half a point or even a full point? I know the cam determines powerband, but does a change in compression ratio alter it?
